What is the birthrate in the U.S.?
United States
The United States has a birth rate of 13 per 1,000, which is 5 births below the world average. Its population growth rate is positive at 0.7%, higher than that of many developed nations. In fiscal year 2016, over one million immigrants (most of whom entered through family reunification) were granted legal residence. Mexico has been the leading source of new residents since the 1965 Immigration Act. China, India, and the Philippines have been in the top four sending countries every year since the 1990s. , approximately 11.4 million residents are illegal immigrants. , 47% of all immigrants are Hispanic, 26% are Asian, 18% are white and 8% are black. The percentage of immigrants who are Asian is increasing while the percentage who are Hispanic is decreasing. The estimated number of illegal immigrants dropped to 10.7 million in 2017, down from a peak of 12.2 million in 2007. In 2017, 33,000 refugees were resettled in the United States. This was fewer than were resettled in the rest of the world for the first time in decades.
A 2017 Gallup poll concluded that 4.5% of adult Americans identified as LGBT with 5.1% of women identifying as LGBT, compared with 3.9% of men. The highest percentage came from the District of Columbia (10%), while the lowest state was North Dakota at 1.7%.
Sex-selective abortion
In the United States, the sex ratios at birth over the period 1970–2002 were 105 for the white non-Hispanic population, 104 for Mexican Americans, 103 for African Americans and Native Americans, and 107 for mothers of Chinese or Filipino ethnicity. Among Western European countries c. 2001, the ratios ranged from 104 to 107. In the aggregated results of 56 Demographic and Health Surveys in African countries, the birth sex ratio was found to be 103, though there is also considerable country-to-country, and year-to-year variation.
Birthright citizenship in the United States
A Pew Hispanic Center analysis of Census Bureau data determined that about 8 percent of children born in the United States in 2008—about 340,000—were offspring of illegal immigrants. In total, about four million American-born children of illegal immigrant parents resided in this country in 2009, along with about 1.1 million foreign-born children of illegal immigrant parents.
Unintended pregnancy
In 2011, a total of 329,797 babies were born to women aged 15–19 years, for a live birth rate of 31.3 per 1,000 women in this age group.1 This is a record low for U.S. teens in this age group and a drop of 8% from 2010. Birth rates fell 11% for women aged 15–17 years, and 7% for women aged 18–19 years. While reasons for the declines are not clear, teens seem to be less sexually active, and more of those who are sexually active seem to be using birth control than in previous years.
Birth tourism
There are no statistics about which countries have citizens who participate in birth tourism in the United States. The Center for Health Care Statistics estimates that there were 7,462 births to foreign residents in the United States in 2008, the most recent year for which statistics are available. That is a small fraction of the roughly 4.3 million total births that year. The Center for Immigration Studies, a conservative think tank, estimated in 2012 that there were approximately 40,000 annual births to parents in the United States as birth tourists. The Center also estimated in 2012 that total births to temporary immigrants in the United States (e.g., tourists, students, guest workers) could be as high as 200,000.
Birth rate
The 2016 average of 18.6 births per 1,000 total population is estimated to be about 4.3 births/second or about 256 births/minute for the world.

Health care in the United States
A report released in April 2008 by the Foundation for Child Development, which studied the period from 1994 through 2006, found mixed results for the health of children in the U.S. Mortality rates for children ages 1 through 4 dropped by a third, and the percentage of children with elevated blood lead levels dropped by 84%. The percentage of mothers who smoked during pregnancy also declined. On the other hand, both obesity and the percentage of low-birth weight babies increased. The authors note that the increase in babies born with low birth weights can be attributed to women delaying childbearing and the increased use of fertility drugs.
Irish Free State
According to one report, in 1924, shortly after the Irish Free State's establishment, the new dominion had the "lowest birth-rate in the world". The report noted that amongst countries for which statistics were available (Ceylon, Chile, Japan, Spain, South Africa, Netherlands, Canada, Germany, Australia, United States, Britain, New Zealand, Finland and the Irish Free State). Ceylon had the highest birth rate at 40.8 per 1,000 while the Irish Free State had a birth rate of just 18.6 per 1,000.
Demography of the United States
From the decline in U.S. birth rates starting in 1958 and the introduction of the birth control pill in 1960, the Baby Boomer normal distribution curve is negatively skewed. The trend in birth rates from 1958 to 1961 show a tendency to end late in the decade at approximately 1969, thus returning to pre-WWII levels, with 12 years of rising and 12 years of declining birth rates. Pre-war birth rates were defined as anywhere between 1939 and 1941 by demographers such as the Taeuber's, Philip M. Hauser and William Fielding Ogburn.
Childlessness
From 2007 to 2011, the fertility rate in the U.S. declined 9%, the Pew Research Center reporting in 2010 that the birth rate was the lowest in U.S. history and that childlessness rose across all racial and ethnic groups to about 1 in 5 versus 1 in 10 in the 1970s.
History of the Poles in the United States
Polish (and Italian) immigrants demonstrated high fecundity in the United States, and in a U.S. Congress report in 1911, Poles were noted as having the single highest birth rate. The 1911 Dillingham Commission had a section devoted to the "Fecundity of Immigrant Women", using data from the 1900 Census. As per Dillingham's findings, there were 40 births per 1,000 Polish people, whereas the non-Polish birth rate was closer to 14 per 1,000. Historians debate the accuracy and sample group of this data, as many Polish immigrants arrived young and of child-bearing age, whereas other ethnics had a lengthy and sustained immigration policy with the United States, meaning multiple generations existed. In reports, the birth rate was very high for Poles and by 1910, the number of children born to Polish immigrants was larger than the number of arriving Polish immigrants. In Polish communities such as rural Minnesota, nearly three-fourths of all Polish women had at least 5 children. The Polish American baby boom lasted from 1906 to 1915 and then fell dramatically, as many of the immigrant mothers had passed out of their prime childbearing age. This was the highest birth rate for American Poles documented in the United States. During the 1920s and 1930s, Polish Americans were coming of age, developing ethnic fraternal organizations, baseball leagues, summer camps, scouting groups, and other youth activities. In large parts of Minnesota and Michigan, over half the population was under sixteen years old. Polish youths created nearly 150 street gangs in Chicago in the 1920s, and in Detroit and Chicago, created the single largest group of inmates in juvenile prisons.
Lindsey Graham
In July 2010, Graham suggested that U.S. citizenship as an automatic birthright guaranteed by the 14th Amendment of the U.S. Constitution should be amended, and that any children born of illegal immigrants inside the borders of the United States should be considered illegal immigrants. Graham alleged that "Half the children born in hospitals on our borders are the children of illegal immigrants." Responding to the Graham claim, "The New York Times" cited a Pew Foundation study estimating that illegal immigrants account for only 8 percent of births in the United States and that 80 percent of the mothers had been in the U.S. for more than one year.
Demographic history of the United States
The U.S. population in 1900 was 76 million. In 1950, it rose to 152 million; by 2000 it had reached 282 million. By 2050, it is expected to reach 420 million.
Richard Easterlin, an economist who has researched economic growth in the United States, explains the growth pattern of American population in the 20th century through fertility rate fluctuations and the decreasing mortality rate. Easterlin has attempted to explain the cause of the Baby Boom and Baby Bust through the "relative income" theory. The "relative income" theory suggests that couples choose to have children based on a couple's ratio of potential earning power and the desire to obtain material objects. This ratio depends on the economic stability of the country in which they live and how people are raised to value material objects. The "relative income" theory explains the Baby Boom by suggesting that the late 1940s and 1950s brought low desires to have material objects, as a result of the Great Depression and WWII, as well as huge job opportunities, because of it being a post war period. These two factors gave rise to a high relative income, which encouraged high fertility. Following this period, the next generation had a greater desire for material objects; however, an economic slowdown in the United States made jobs harder to acquire. This resulted in lower fertility rates, causing the Baby Bust.

Prevalence of teenage pregnancy
However, the trend is decreasing: in 1990, the birth rate was 61.8, and the pregnancy rate 116.9 per thousand. This decline has manifested across all races, although teenagers of African-American and Hispanic descent retain a higher rate, in comparison to that of European-Americans and Asian-Americans. The Guttmacher Institute attributed about 25% of the decline to abstinence and 75% to the effective use of contraceptives.
Colorado
"Note: Births in table don't add up, because Hispanics are counted both by their ethnicity and by their race, giving a higher overall number."In 2017, Colorado recorded the second-lowest fertility rate in the United States outside of New England, after Oregon, at 1.63 children per woman.
United States
The drop in the U.S. fertility rate from 2.08 per woman in 2007 to 1.76 in 2017 was mostly due to the declining birth rate of Hispanics, teenagers, and young women, although the birth rate for older women rose.
Demographics of the world
According to the CIA - The World Factbook, the country with the highest birth rate currently is Niger at 51.26 births per 1000 people. The country with the lowest birth rate is Japan at 7.64 births per 1000 people. Hong Kong, a Special Administrative Region of China, is at 7.42 births per 1000 people. As compared to the 1950s, birth rate was at 36 births per 1000 in the 1950s, birth rate has declined by 16 births per 1000 people. In July 2011, the U.S. National Institutes of Health announced that the adolescent birth rate continues to decline.
Conemaugh Valley School District
Pennsylvania's birth rate has been declining for two decades. According to data from the Pennsylvania Department of Health, in 1990, the Commonwealth of Pennsylvania's birth rate was 171,053. In 2000, Pennsylvania's birth rate was 145,874. Finally in 2011, the State's birth rate declined further to 142,021. From 2000 to 2009, the number of babies born in rural counties declined 5 percent. Urban counties have also experienced a decline in the number of school aged children. From 2000-2010 urban Pennsylvania counties had a 3 percent decline in the number of residents under 18 years old. In 2010, there were 2.07 million residents, or 22 percent of the urban population, who were under age 18.

In 2000, the County's birth rate declined to 614 births. In 2011, Columbia County's birth rate was 620 births.
Populated places with highest incidence of multiple birth
In 2008, Massachusetts has emerged as the most prolific producer of multiple births in the United States. The state has a twin birth rate of 4.5 for every 100 live births, compared with a national rate of 3.2.
Sterilization (medicine)
Because of the emphasis placed on childbearing as the most important role of women, not having children was traditionally seen as a deficiency or due to fertility problems. However, access to contraception and abortion, new economic and educational opportunities, and changing ideas about motherhood have led to new reproductive experiences for women in the United States, particularly for women who choose to be childless. Scholars define "voluntarily childless" women as "women of childbearing age who are fertile and state that they do not intend to have children, women of childbearing age who have chosen sterilization, or women past childbearing age who were fertile but chose not to have children." 
In industrialized countries such as the United Kingdom, those of Western Europe, and the United States, the fertility rate has declined below or near the population replacement rate of two children per woman. Women are having children at a later age, and most notably, an increasing number of women are choosing not to bear children at all. According to the U.S. Census Bureau's American Community Survey, 46% of women aged 15 to 44 were childless in June 2008 compared to 35% of childless women in 1976. The personal freedoms of a childless lifestyle and the ability to focus on other relationships were common motivations underlying the decision to be voluntarily childless. Such personal freedoms included increased autonomy and improved financial positions. The couple could engage in more spontaneous activities because they didn't need a babysitter or to consult with someone else. Women had more time to devote to their careers and hobbies. Regarding other relationships, some women chose to forgo children because they wanted to maintain the "type of intimacy that they found fulfilling" with their partners. Although voluntary childlessness was a joint decision for many couples, "studies have found that women were more often the primary decision makers. There is also some evidence that when one partner (either male or female) was ambivalent, a strong desire not to have children on the side of the other partner was often the deciding factor." 'Not finding a suitable partner at an appropriate time in life" was another deciding factor, particularly for ambivalent women.
Environmental issues in the United States
The total U.S. population crossed the 100 million mark around 1915, the 200 million mark in 1967, and the 300 million mark in 2006 (estimated on Tuesday, October 17). The U.S. population more than tripled during the 20th century — a growth rate of about 1.3 percent a year — from about 76 million in 1900 to 281 million in 2000. This is unlike most European countries, especially Germany, Russia, Italy and Greece, whose populations are slowly declining, and whose fertility rates are below replacement.
Demographics of Saudi Arabia
The following data has been retrieved from the CIA World Factbook as of 2018.Saudi Arabia is ranked 111th in comparison to the world with a birth rate of 15.6 births per 1,000 people according to the CIA World Factbook in 2018. The nation's death rate is raked 220th worldwide with 3.3 deaths per 1,000 people. Although birth rates have decreased in the last two decades, rates of decline fail to match the significant decline in death rates. Because of this, Saudi Arabia has experienced a population explosion in the last 40 years, and continues to grow at a rate of 1.63% per year. Saudi Arabia’s population growth continues to be 0.295% higher than population growth rates in the Middle East and North Africa. Infant mortality rates have declined dramatically in the past twenty years from 25.3 deaths per 1,000 live births in 1995 to 6.3 deaths in 2017, according to the World Bank. Saudi Arabia has a substantially lower infant mortality rate in comparison to the Middle East and North Africa region, which continues to face a high of 19.3 deaths for every 1,000 live births as of 2017. This significant reduction can be attributed to rising access to modern healthcare across the country, ranking 26th worldwide for healthcare system quality. The construction of new hospitals and primary healthcare centers across the Kingdom, as well as healthcare during pregnancy and increased use of vaccinations account for a decline in infant mortality and increased life expectancy.
Birthday
According to a public database of births, birthdays in the United States are quite evenly distributed for the most part, but there tend to be more births in September and October. This may be because there is a holiday season nine months before (the human gestation period is about nine months), or because the longest nights of the year also occur in the Northern Hemisphere nine months before. However, it appears the holidays have more of an effect on birth rates than the winter: New Zealand, a Southern Hemisphere country, has the same September and October peak with no corresponding peak in March and April. The least common birthdays tend to fall around public holidays, such as Christmas, New Years Day and fixed-date holidays such as July 4 in the US. This is probably due to hospitals and birthing centres not offering labor inductions and elective Caesarean sections on public holidays.
Maternal death
Even though 99% of births in the United States are attended by some form of skilled health professional, the maternal mortality ratio in 2015 was 14 deaths per 100,000 live births and it has been shown that the maternal mortality rate has been increasing. Also, the United States is not as efficient at preventing pregnancy-related deaths when compared to most of the other developed nations.
Birth rate
In July 2011, the UK's Office for National Statistics (ONS) announced a 2.4 percent increase in live births in the UK in 2010. This is the highest birth rate in the UK in 40 years. However, the UK record year for births and birth rate remains 1920 (when the ONS reported over 957,000 births to a population of "around 40 million").
Fear of children
While there are many families in the world, not all couples or even humans desire to have families or children. The United States Bureau of the Census conducted a study in 1971, which they say the data still seems to be the same today concerning birth rates and parent-to-child ratios. They believe it is too early to say that (increased rates of childless families) foretell a future increase of childless homes in general or just later birth. The number of married couples voluntarily choosing to be childless are only increasing. As social trends are hard to predict and therefore fertility expectations, attitudes, behaviors and such are uneasy to consistently gather data for, leaving voluntarily childlessness hard to track. There is a forum on the popular website, Reddit, where self-described childfree individuals from around the world discuss the childfree lifestyle.
Birth rate
The birth rate (technically, births/population rate) is the total number of live births per 1,000 in a population in a year or period. The rate of births in a population is calculated in several ways: live births from a universal registration system for births, deaths, and marriages; population counts from a census, and estimation through specialized demographic techniques. The birth rate (along with mortality and migration rate) are used to calculate population growth.
Family structure in the United States
When Moynihan wrote in 1965 on the coming destruction of the Black family, the out-of-wedlock birthrate was 25% amongst Blacks. In 1991, 68% of Black children were born outside of marriage. In 2011, 72% of Black babies were born to unwed mothers.
History of women in the United States
Marriage and motherhood came back as prosperity empowered couples who had postponed marriage. The birth rate started shooting up in 1941, paused in 1944–45 as 12 million men were in uniform, then continued to soar until reaching a peak in the late 1950s. This was the "Baby Boom."
Adolescent sexuality in the United States
Teenage birth rates, as opposed to pregnancies, peaked in 1991, when there were 61.8 births per 1,000 teens, and the rate dropped in 17 of the 19 years that followed. One in four American women who had sex during their teenage years will have a baby before they are married, compared to only one in ten who wait until they are older. Even more will experience a pregnancy. Of women who have sex in their teens, nearly 30% will conceive a child before they are married. Conversely, only 15% of women who do not have sex in their teens will become pregnant before they are married. Of all women, 16% will be teen mothers.

Pennsylvania's birth rate has been declining for two decades. According to data from the Pennsylvania Department of Health, in 1990, the Commonwealth of Pennsylvania's birth rate was 171,053. In 2000, Pennsylvania's birth rate was 145,874. Finally in 2011, the State's birth rate declined further to 142,021. From 2000 to 2009, the number of babies born in rural counties declined 5 percent. Urban counties have also experienced a decline in the number of school aged children. From 2000-2010 urban Pennsylvania counties had a 3 percent decline in the number of residents under 18 years old. In 2010, there were 2.07 million residents, or 22 percent of the urban population, who were under age 18.
Birthright citizenship in the United States
The policy stems from the Citizenship Clause of the Fourteenth Amendment to the United States Constitution, stating "[a]ll persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside", and was meant to override the 1857 "Dred Scott v. Sandford" decision that denied African Americans citizenship. The application of birthright citizenship to children of undocumented immigrants remains controversial among right-wing politicians. The Pew Hispanic Center estimates that approximately 7.5% of all births in the U.S. (about 300,000 births per year) are to illegal immigrants. The Pew Hispanic Center also estimates that there are 4.5 million children who were born to illegal immigrants that received citizenship via birth in the United States; while the Migration Policy Institute estimates that there are 4.1 million children. Both estimates exclude anyone eighteen and older who might have benefited.

Urban counties have also experienced a decline in the number of school aged children. From 2000-2010 urban Pennsylvania counties had a 3 percent decline in the number of residents under 18 years old. In 2010, there were 2.07 million residents, or 22 percent of the urban population, who were under age 18.
Birth rate
States strict in enforcing child support have up to 20 percent fewer unmarried births than states that are lax about getting unmarried dads to pay, the researchers found. Moreover, according to the results, if all 50 states in the United States had done at least as well in their enforcement efforts as the state ranked fifth from the top, that would have led to a 20 percent reduction in out-of-wedlock births.
Illegal immigration to the United States
The Pew Hispanic Center determined that according to an analysis of Census Bureau data about 8 percent of children born in the United States in 2008—about 340,000—were offspring of illegal immigrants. (The report classifies a child as offspring of illegal immigrants if "either" parent is unauthorized.) In total, 4 million U.S.-born children of illegal immigrant parents resided in this country in 2009 (alongside 1.1 million foreign-born children of illegal immigrant parents). These infants are, according to the longstanding administrative interpretation of the Fourteenth Amendment to the United States Constitution, American citizens from birth. Congress has never legislated, nor the Supreme Court specifically ruled on whether babies born to visiting foreign nationals are eligible for automatic US Citizenship. These children are sometimes referred to as anchor babies because of the belief that the mother gave birth in the United States as a way to anchor their family in the US.
Health care in the United States
The United States is within the Region of the Americas or AMRO (a World Health Organization classification). Within AMRO, the U.S. had the third lowest under-five child mortality rate (U5MR) in 2015. In 2015, the under-five child mortality rate was 6.5 deaths per 1000 live births, less than half the regional average of 14.7. The U.S. had the second lowest maternal mortality in AMRO, 14 per 100,000 live births, well below the regional average of 52. Life expectancy at birth for a child born in the U.S. in 2015 is 81.2 (females) or 76.3 (males) years, compared to 79.9 (females) or 74 (males) years (AMRO regional estimates). Globally, average life expectancy is 73.8 for females and 69.1 for males born in 2015.
Sex-selective abortion
The estimates for birth sex ratios, and thus derived sex-selective abortion, are a subject of dispute as well. For example, United States' CIA projects the birth sex ratio for Switzerland to be 106, while the Switzerland's Federal Statistical Office that tracks actual live births of boys and girls every year, reports the latest birth sex ratio for Switzerland as 107. Other variations are more significant; for example, CIA projects the birth sex ratio for Pakistan to be 105, United Nations FPA office claims the birth sex ratio for Pakistan to be 110, while the government of Pakistan claims its average birth sex ratio is 111.
Single parent
In the United States, since the 1960s, there has been a marked increase in the number of children living with a single parent. The 1980 United States Census reported that 19.5% were single parent households. From 1980 to 2009, the percentage of single-parent households jumped to 29.5%.
The jump was caused by an increase in births to unmarried women and by the increasing prevalence of divorces among couples. In 2010, 40.7% of births in the US were to unmarried women. In 2000, 11% of children were living with parents who had never been married, 15.6% of children lived with a divorced parent, and 1.2% lived with a parent who was widowed. The results of the 2010 United States Census showed that 27% of children live with one parent, consistent with the emerging trend noted in 2000. The most recent data of December 2011 shows approximately 13.7 million single parents in the U.S. Mississippi leads the nation with the highest percent of births to unmarried mothers with 54% in 2014, followed by Louisiana, New Mexico, Florida and South Carolina.

Pennsylvania's birth rate has been declining for two decades. According to data from the Pennsylvania Department of Health, in 1990, the Commonwealth of Pennsylvania's annual birth rate was 171,053. In 2000, Pennsylvania's birth rate declined to 145,874. Finally in 2011, the State's birth rate declined further to 142,021. In Lehigh County, the birth rate was 4,147 in 1990. In 2000, Lehigh County's birth rate declined to 3,770 births.
Finland
Life expectancy has increased from 71 years for men and 79 years for women in 1990 to 79 years for men and 84 years for women in 2017. The under-five mortality rate has decreased from 51 per 1,000 live births in 1950 to 2.3 per 1,000 live births in 2017 ranking Finland's rate among the lowest in the world. The fertility rate in 2014 stood at 1.71 children born/per woman and has been below the replacement rate of 2.1 since 1969. With a low birth rate women also become mothers at a later age, the mean age at first live birth being 28.6 in 2014. A 2011 study published in "The Lancet" medical journal found that Finland had the lowest stillbirth rate out of 193 countries, including the UK, France and New Zealand.
Demographics of Uruguay
As a result of the low birth rate, high life expectancy, and relatively high rate of emigration of younger people, Uruguay's population is quite mature. In 2006, the country had a birth rate of 13.91 births per thousand population, lower than neighboring countries Argentina (16.73 births/1000 population)[3] and Brazil (16.56 births/1,000 population).
Demography of the United States
In 2010, the state with the lowest fertility rate was Rhode Island, with a rate of 1.63, while Utah had the greatest rate with a rate of 2.45. This correlates with the ages of the states' populations: Rhode Island has the ninth-oldest median age in the US—39.2—while Utah has the youngest—29.0.
Adoption
Although adoption is today practiced globally, the United States has the largest number of children adopted per 100 live births. The table below provides a snapshot of Western adoption rates. Adoption in the United States still occurs at nearly three times those of its peers although the number of children awaiting adoption has held steady in recent years, hovering between 133,000 and 129,000 during the period 2002 to 2006.
Demography of the United States
Sex ratios:The most densely populated state is New Jersey (1,121/mi or 433/km). See List of U.S. states by population density for maps and complete statistics.
13% of the population was foreign-born in 2009 – a rise of 350% since 1970 when foreign-born people accounted for 3.7% of the population, including 11.2 million illegal immigrants, 80% of whom come from Latin America. Latin America is the largest region-of-birth group, accounting for over half (53%) of all foreign born population in US, and thus is also the largest source of both legal and illegal immigration to US. In 2011, there are 18.1 million naturalized citizens in the United States, accounting for 45% of the foreign-born population (40.4 million) and 6% of the total US population at the time, and around 680,000 legal immigrants are naturalized annually.
Demographics of New England
The six states of New England have the lowest birth rate in the U.S.
Demography of the United States
Subdivided groups are present when peak boom years or inverted peak bust years are present, and may be represented by a normal or inverted bell-shaped curve (rather than a straight curve). The boom subdivided cohorts may be considered as "pre-peak" (including peak year) and "post-peak". The year 1957 was the baby boom peak with 4.3 million births and 122.7 fertility rate. Although post-peak births (such as trailing edge boomers) are in decline, and sometimes referred to as a "bust", there are still a "relatively" large number of births. The dearth-in-birth bust cohorts include those up to the valley birth year, and those including and beyond, leading up to the subsequent normal birth rate. The baby boom began around 1943 to 1946.
Teenage pregnancy
In 2001, the teenage birth rate in the U.S. was the highest in the developed world, and the teenage abortion rate is also high. In 2005 in the U.S., the majority (57%) of teen pregnancies resulted in a live birth, 27% ended in an induced abortion, and 16% in a fetal loss. The U.S. teenage pregnancy rate was at a high in the 1950s and has decreased since then, although there has been an increase in births out of wedlock. The teenage pregnancy rate decreased significantly in the 1990s; this decline manifested across all racial groups, although teenagers of African-American and Hispanic descent retain a higher rate, in comparison to that of European-Americans and Asian-Americans. The Guttmacher Institute attributed about 25% of the decline to abstinence and 75% to the effective use of contraceptives. While in 2006 the U.S. teen birth rate rose for the first time in fourteen years, it reached a historic low in 2010: 34.3 births per 1,000 women aged 15–19.
Birth rate
According to U.S. federal-government data released in March 2011, births fell four percent from 2007 to 2009 (the largest drop in the U.S. for any two-year period since the 1970s).
Births have declined for three consecutive years, and are now seven percent below the 2007 peak. This drop has continued through 2010, according to data released by the U.S. National Center for Health Statistics in June 2011. Experts have suggested that this decline is a reflection of unfavorable economic conditions. The connection between birth rate and economic conditions stems from the fact that US birth rates have fallen to levels comparable to those during the Great Depression during the 1930s. A state-level look at fertility, based on a report published by the Pew Research Center in October 2011, points out the strong correlation between lower birth rates and economic distress. In 2008, North Dakota had the nation's lowest unemployment rate (3.1 percent) and was the only state to show an increase (0.7 percent) in its birth rate. All other states either remained the same or declined.
Human sex ratio
In the United States, the sex ratios at birth over the period 1970–2002 were 1.05 for the white non-Hispanic population, 1.04 for Mexican Americans, 1.03 for African Americans and Indians, and 1.07 for mothers of Chinese or Filipino ethnicity. Among Western European countries c. 2001, the ratios ranged from 1.04 in Belgium to 1.07 in Switzerland, Italy, Ireland and Portugal. In the aggregated results of 56 Demographic and Health Surveys in African countries, the ratio is 1.03, albeit with considerable country-to-country variation.
There is controversy whether sex ratios outside the 103-107 range are due to sex-selection, as suggested by some scholars, or due to natural causes. Some scholars argue that strong socioeconomic factors such as the dowry system in India and the one child policy of China are responsible for prenatal sex-selection. In a widely cited article, Amartya Sen supported such views. Other researchers argue that an unbalanced sex ratio should not be automatically held as evidence of prenatal sex-selection; Michel Garenne reports that many African nations have, over decades, witnessed birth sex ratios below 100, that is more girls are born than boys. Angola, Botswana and Namibia have reported birth sex ratios between 94 and 99, which is quite different than the presumed "normal" sex ratio, meaning that significantly more girls have been born in such societies.
Birth rate
The region of Sub-Saharan Africa has the highest birth rate in the world. As of 2016, Niger, Mali, Uganda, Zambia, and Burundi have the highest birth rates in the world. This is part of the fertility-income paradox, as these countries are very poor, and it may seem counter-intuitive for families there to have so many children. The inverse relationship between income and fertility has been termed a "demographic-economic "paradox"" by the notion that greater means would enable the production of more offspring as suggested by the influential Thomas Malthus.
Comparison of the healthcare systems in Canada and the United States
The United States and Canada have different racial makeups, different obesity rates and different alcoholism rates, which would likely cause the US to have a shorter average life expectancy and higher infant mortality even with equal healthcare provided. The US population is 12.2% African Americans and 16.3% Hispanic Americans (2010 Census), whereas Canada has only 2.5% African Canadians and 0.97% Hispanic Canadians (2006 Census). African Americans have higher mortality rates than any other racial or ethnic group for eight of the top ten causes of death. The cancer incidence rate among African Americans is 10% higher than among European Americans. U.S. Latinos have higher rates of death from diabetes, liver disease, and infectious diseases than do non-Latinos. Adult African Americans and Latinos have approximately twice the risk as European Americans of developing diabetes. The infant mortality rates for African Americans is twice that of whites. Unfortunately, directly comparing infant mortality rates between countries is difficult, as countries have different definitions of what qualifies as an infant death.
Teenage pregnancy in the United States
Although there is a noticeable decline in U.S. teen pregnancy, the current rate is still 2-4 times more than in Canada, France, Great Britain, and Sweden. The biggest difference in the rate of pregnancies in the United States compared to the other countries is that in America there is a very high unintended pregnancy rate. This unintended pregnancy rate is higher than the total teenage pregnancy rate in all of the four countries.
In 2010 there was a rate of 57 pregnancies per 1,000 women aged 15–19. Most of those women reported that it was an unplanned pregnancy. This shows a 15% drop in pregnancies from 2008 to 2010. There is a huge decline in adolescent pregnancy for the nation as a whole. The cause of these declines are from abstaining from sex or better use of contraceptives. Birth rates among younger teens ages 15–17 have also fallen faster – dropping by 50%, compared with a 39% decline among older teens ages 18 and 19. Researchers have concluded that these declines stem from improvement in use of contraceptives.
Preterm birth
Preterm birth complicates the births of infants worldwide affecting 5% to 18% of births. In Europe and many developed countries the preterm birth rate is generally 5–9%, and in the USA it has even risen to 12–13% in the last decades.
Preterm birth
Further, in the U.S. and the UK, black women have preterm birth rates of 15–18%, more than double than that of the white population. Filipinos are also at high risk of premature birth, and it is believed that nearly 11–15% of Filipinos born in the U.S. (compared to other Asians at 7.6% and whites at 7.8%) are premature. Filipinos being a big risk factor is evidenced with the Philippines being the 8th highest ranking in the world for preterm births, the only non-African country in the top 10. This discrepancy is not seen in comparison to other Asian groups or Hispanic immigrants and remains unexplained.
Stillbirth
The average stillbirth rate in the United States is approximately 1 in 160 births, which is roughly 26,000 stillbirths each year. In Australia, England, Wales, and Northern Ireland, the rate is approximately 1 in every 200 births; in Scotland, 1 in 167. Rates of stillbirth in the United States have decreased by about 2/3 since the 1950s.
Low birth weight
A study by the Agency for Healthcare Research and Quality (AHRQ) found that of the 3.8 million births that occurred in the United States in 2011, approximately 6.1% (231,900) were diagnosed with low birth weight (<2,500 g). Approximately 49,300 newborns (1.3%) weighed less than 1,500 grams (VLBW). Infants born at low birth weight are at a higher risk for developing neonatal infection.
Childbirth
Compared to other developed nations, the United States also has high infant mortality rates. The Trust for America's Health reports that as of 2011, about one third of American births have some complications; many are directly related to the mother's health including increasing rates of obesity, type 2 diabetes, and physical inactivity. The U.S. Centers for Disease Control and Prevention (CDC) has led an initiative to improve woman's health previous to conception in an effort to improve both neonatal and maternal death rates.
Interracial adoption
Interracial adoption grew significantly from 1999 to 2005 where it reached its peak year at 585 adoptions to the United States. Following 2005, interracial adoption into the US declined with 288 adoptions in the year 2011. From 1999 to 2011, there has been 233,934 adoptions into the United States from other countries across the globe. Of the total adoptions, 39.4% (92,202 children) were under the age of 12 months. Also, 63% (146,516 children) were female. Overall, children from China were the most common to be adopted. 66,630 were from China and Russia was the second largest country with 45,112 children.
List of U.S. states and territories by birth and death rates
This article includes a list of U.S. states sorted by birth and death rate, expressed per 1,000 inhabitants, for 2016, using the most recent data available from the U.S. National Center for Health Statistics.
Demography of the United States
The U.S. total fertility rate as of 2010 census is 1.931:

Total fertility rate
The total fertility rate in the US after World War II peaked at about 3.8 children per woman in the late 1950s and by 1999 was at 2 children. The fertility rate of the total US population was just below the replacement level in 1979. The fertility of the population of the United States is currently below replacement among those native born, and above replacement among immigrant families, most of whom come to the U.S. from countries with higher fertility than that of the U.S. However, the fertility rates of immigrants to the U.S. have been found to decrease sharply in the second generation, correlating with improved education and income. As of the beginning of 2016, there are 59.8 births per 1,000 women aged 15–44; this is the lowest number since records have been kept since 1909.Dynamics:
Demographics of India
Some activists believe India's 2011 census shows a serious decline in the number of girls under the age of seven – activists posit that eight million female fetuses may have been aborted between 2001 and 2011. These claims are controversial. Scientists who study human sex ratios and demographic trends suggest that birth sex ratio between 1.08 and 1.12 can be because of natural factors, such as the age of mother at baby's birth, age of father at baby's birth, number of babies per couple, economic stress, endocrinological factors, etc. The 2011 census birth sex ratio in India, of 917 girls to 1000 boys, is similar to 870–930 girls to 1000 boys birth sex ratios observed in Japanese, Chinese, Cuban, Filipino and Hawaiian ethnic groups in the United States between 1940 and 2005. They are also similar to birth sex ratios below 900 girls to 1000 boys observed in mothers of different age groups and gestation periods in the United States.
Birth rate
The research center's study also found evidence of a correlation between economic difficulties and fertility decline by race and ethnicity. Hispanics (particularly affected by the recession) have experienced the largest fertility decline, particularly compared to Caucasians (who have less economic hardship and a smaller decline in fertility). In 2008–2009 the birth rate declined 5.9 percent for Hispanic women, 2.4 percent for African American women and 1.6 percent for white women. The relatively large birth rate declines among Hispanics mirror their relatively large economic declines, in terms of jobs and wealth. According to the statistics using the data from National Centre for Health Statistics and U.S. Census Bureau, from 2007 to 2008, the employment rate among Hispanics declined by 1.6 percentage points, compared with declines of 0.7 points for whites. The unemployment rate shows a similar pattern—unemployment among Hispanics increased 2.0 percentage points from 2007 to 2008, while for whites the increase was 0.9 percentage points. A recent report from the Pew Hispanic Center revealed that Hispanics have also been the biggest losers in terms of wealth since the beginning of the recession, with Hispanic households losing 66% of their median wealth from 2005 to 2009. In comparison, black households lost 53% of their median wealth and white households lost only 16%. In facts, Hispanics, who have been hit the hardest in terms of employment and wealth, have also experienced the largest fertility declines since the onset of the recession because the birth rate declines of Hispanic women is the highest while comparing to the White women. Since, the unemployment rate has been increasing, the birth rate decline has been decreasing.
Demography of the United States
The drop in the birth rate from 2007 to 2009 is believed to be associated with the Great Recession.
Demographic history of the United States
The total fertility rate of the United States jumped from 2.49 in 1945 to 2.94 in 1946, a rise of 0.45 children therefore beginning the baby boom. It continued to rise throughout the 1940s to reach 3.10 in 1950 with a peak of 3.77 in 1957. Declining slowly thereafter to 3.65 in 1960 and finally a steep from decline after 1964, therefore ending the baby boom.
Generation X
In the U.S., some called Generation Xers the "baby bust" generation because of the drop in the birth rate following the baby boom. The drop in fertility rates in America began in the late 1950s. But according to authors and demographers William Strauss and Neil Howe (who use 1961 to 1981 for Gen X birth years), by 1991 there were approximately 88.5 million Gen Xers in the U.S.
Demographics of the world
Birth rates ranging from 10-20 births per 1000 are considered low, while rates from 40-50 births per 1000 are considered high. There are problems associated with both an extremely high birth rate and an extremely low birth rate. High birth rates can cause stress on the government welfare and family programs to support a youthful population. Additional problems faced by a country with a high birth rate include educating a growing number of children, creating jobs for these children when they enter the workforce, and dealing with the environmental effects that a large population can produce. Low birth rates can put stress on the government to provide adequate senior welfare systems and also the stress on families to support the elders themselves. There will be less children or working age population to support the constantly growing aging population.

Sex-selective abortion
Other countries with large populations but high sex ratios include Pakistan and Vietnam. United Nations Population Fund, in its 2012 report, claims the birth sex ratio of Vietnam at 111 with its densely populated Red River Delta region at 116; for Pakistan, the UN estimates the birth sex ratio to be 110. The urban regions of Pakistan, particularly its densely populated region of Punjab, report a sex ratio above 112 (less than 900 females per 1000 males). Hudson and Den Boer estimate the resulting deficit to be about 6 million missing girls in Pakistan than what would normally be expected. Three different research studies, according to Klausen and Wink, note that Pakistan had the world's highest percentage of missing girls, relative to its total pre-adult female population. Taiwan has reported a sex ratio at birth between 1.07 and 1.11 every year, across 4 million births, over the 20-year period from 1991 to 2011, with the highest birth sex ratios in the 2000s. Sex-selective abortion is reported to be common in South Korea too, but its incidence has declined in recent years. As of 2015, South Korea's sex ratio at birth was 1.07 male/female. In 2015, Hong Kong had a sex ratio at birth of 1.12 male/female. A 2001 study on births in the late 1990s concluded that "sex selection or sex-selective abortion might be practiced among Hong Kong Chinese women".
Demographic transition
Today, the U.S. is recognized as having both low fertility and mortality rates. Specifically, birth rates stand at 14 per 1000 per year and death rates at 8 per 1000 per year.
Demographics of the world
As of 2009, the average birth rate (unclear whether this is the weighted average rate per country [with each country getting a weight of 1], or the unweighted average of the entire world population) for the whole world is 19.95 per year per 1000 total population, a 0.48% decline from 2003's world birth rate of 20.43 per 1000 total population.
Teenage pregnancy
Worldwide, teenage pregnancy rates range from 143 per 1000 in some sub-Saharan African countries to 2.9 per 1000 in South Korea. In the U.S., 82% of pregnancies in those between 15 and 19 are unplanned. Among OECD developed countries, the U.S., the UK and New Zealand have the highest level of teenage pregnancy, while Japan and South Korea have the lowest in 2001. According to UNFPA, “In every region of the world – including high-income countries – girls who are poor, poorly educated or living in rural areas are at greater risk of becoming pregnant than those who are wealthier, well-educated or urban. This is true on a global level, as well: 95 per cent of the world’s births to adolescents (aged 15–19) take place in developing countries. Every year, some 3 million girls in this age bracket resort to unsafe abortions, risking their lives and health.”
Birth rate
According to the CIA's "The World Factbook", the country with the highest birth rate is Niger at 6.49 children born per woman and the country with the lowest birth rate is Taiwan, at 1.13 children born per woman.
Unassisted childbirth
United States:
The National Center for Health Statistics reports that of the 4.1 million babies born in the United States in 2004, more than 7,000 were born at home without a midwife or physician attending. It is unknown what portion of these births, roughly equivalent to a sixth of 1% of the nation's annual total, occurred by choice.
Sociology of the family
In the United States, 82.5 million women are mothers of all ages, while the national average age of first child births is 25.1 years. In 2008, 10% of births were to teenage girls, and 14% were to women ages 35 and older. In the United States, a study found that the average woman spends 5 years working and building a career before having children, and mothers working non-salary jobs began having children at age 27, compared to mothers with salary positions, who became pregnant at age 31. The study shows that the difference in age of child birth is related to education, since the longer a woman has been in school, the older she will be when she enters the workforce.
Canton Area School District
Pennsylvania's birth rate has been declining for two decades. According to data from the Pennsylvania Department of Health, in 1990, the Commonwealth of Pennsylvania's birth rate was 171,053. In 2000, Pennsylvania's birth rate was 145,874. Finally in 2011, the State's birth rate declined further to 142,021. From 2000 to 2009, the number of babies born in rural counties declined 5 percent. Urban counties have also experienced a decline in the number of school aged children. From 2000-2010 urban Pennsylvania counties had a 3 percent decline in the number of residents under 18 years old. In 2010, there were 2.07 million residents, or 22 percent of the urban population, who were under age 18.
Infant mortality
Of the 27 most developed countries, the U.S. has the highest Infant Mortality Rate, despite spending much more on health care per capita. Significant racial and socio-economic differences in the United States affect the IMR, in contrast with other developed countries, which have more homogeneous populations. In particular, IMR varies greatly by race in the US. The average IMR for the whole country is therefore not a fair representation of the wide variations that exist between segments of the population. Many theories have been explored as to why these racial differences exist with socio economic factors usually coming out as a reasonable explanation. However, more studies have been conducted around this matter, and the largest advancement is around the idea of stress and how it affects pregnancy.
Immigration to the United States
By 1970, immigrants accounted for 4.7 percent of the US population and rising to 6.2 percent in 1980, with an estimated 12.5 percent in 2009. , 25% of US residents under age 18 were first- or second-generation immigrants. Eight percent of all babies born in the U.S. in 2008 belonged to illegal immigrant parents, according to a recent analysis of U.S. Census Bureau data by the Pew Hispanic Center.
Texas
Texas has the seventh highest birth rate in the United States, with nearly 400,000 babies born each year. Over half of all Texas births are paid by Medicaid, totaling over $2.2 billion per year in birth and delivery-related services for mothers and infants. Studies have found that infant mortality is usually caused by birth defects, pre-term birth, low birth weight, Sudden Infant Death Syndrome, and pregnancy complications. The average amount spent in the first year of life for a preterm birth with major complications (excluding extreme prematurity) is $19,059, and $4,019 for a preterm birth without major complications compared to $410 for an uncomplicated, term birth.
United School District (Pennsylvania)
Indiana County's live birth rate was 1,046 births in 1990. Indiana County's live birth rate in 2000 declined sharply to 855 births, while in 2011 it had declined further to 842 babies. Over the past 50 years (1960 to 2010), rural Pennsylvania saw a steady decline in both the number and proportion of residents under 18 years old. In 1960, 1.06 million rural residents, or 35 percent of the rural population, were children. Pennsylvania's birth rate has been declining for two decades. According to data from the Pennsylvania Department of Health, in 1990, the Commonwealth of Pennsylvania's birth rate was 171,053. In 2000, Pennsylvania's birth rate was 145,874. Finally in 2011, the State's birth rate declined further to 142,021. From 2000 to 2009, the number of babies born in rural counties declined 5 percent. Urban counties have also experienced a decline in the number of school aged children. From 2000-2010 urban Pennsylvania counties had a 3 percent decline in the number of residents under 18 years old. In 2010, there were 2.07 million residents, or 22 percent of the urban population, who were under age 18.
Mid-twentieth century baby boom
Economist and demographer Richard Easterlin in his "Twentieth Century American Population Growth" (2000), explains the growth pattern of American population in the 20th century by examining the fertility rate fluctuations and the decreasing mortality rate. Easterlin attempts to prove the cause of the baby boom and baby bust by the "relative income" theory, despite the various other theories that these events have been attributed to. The "relative income" theory suggests that couples choose to have children based on a couple's ratio of potential earning power and the desire to obtain material objects. This ratio depends on the economic stability of the country and how people are raised to value material objects. The "relative income" theory explains the baby boom by suggesting that the late 1940s and the 1950s brought low desires to have material objects, because of the Great Depression and World War II, as well as plentiful job opportunities (being a post-war period). These two factors gave rise to a high relative income, which encouraged high fertility. Following this period, the next generation had a greater desire for material objects, however an economic slowdown in the United States made jobs harder to acquire. This resulted in lower fertility rates causing the Baby Bust.
Unintended pregnancy
Over 92% of abortions are the result of unintended pregnancy, unintended pregnancies result in about 800,000 abortions/year. In 2001, 44% of unintended pregnancies resulted in births, and 42% resulted in induced abortion and the rest in miscarriage. It is estimated that more than half of US women have had an unintended pregnancy by age 45. The U.S. states with the highest levels of abortions performed were Delaware, New York and New Jersey, with rates of 40, 38 and 31 per 1,000 women, respectively. High rates were also seen in the states of Maryland, California, Florida, Nevada and Connecticut with rates of 25 to 29 per 1,000 women. The state with the lowest abortion rate was Wyoming, which had less than 1 per 1,000 women, followed by Mississippi, Kentucky, South Dakota, Idaho and Missouri with rates of 5 to 6 abortions per 1,000 women.
Birth rate
In July 2011, the U.S. National Institutes of Health announced that the adolescent birth rate continues to decline. In 2013, teenage birth rates in the U.S. were at the lowest level in U.S. history. Teen birth rates in the U.S. have decreased from 1991 through 2012 (except for an increase from 2005–2007). The other aberration from this otherwise-steady decline in teen birth rates is the six percent decrease in birth rates for 15- to 19-year-olds between 2008 and 2009. Despite the decrease, U.S. teen birth rates remain higher than those in other developed nations. Racial differences affect teen birth and pregnancy rates: American Indian/Alaska Native, Hispanic, and non-Hispanic black teen pregnancy rates are more than double the non-Hispanic white teenage birth rate.
Health care in the United States
The 2015 global average for under-five child mortality was 42.5 per 1000 live births. The U.S.’s under-five child mortality of 6.5 is more than 6 times less. The 2015 global average for maternal mortality was 216, the United States' average of 14 maternal deaths 100,000 live births is more than 15 times less, however Canada had half as many (7) and Finland, Greece, Iceland and Poland each only had 3. While not as high in 2015 (14) as in 2013 (18.5), maternal deaths related to childbirth have shown recent increases; in 1987, the mortality ratio was 7.2 per 100,000. As of 2015, the American rate is double the maternal mortality rate in Belgium or Canada, and more than triple the rate in the Finland as well as several other Western European countries.
Teenage pregnancy in the United States
Teenage birth rates, as opposed to pregnancies, peaked in 1991, when there were 61.8 births per 1,000 teens, and the rate dropped in 17 of the 19 years that followed. 3 in 10 American girls will get pregnant before age 20. That are almost 750,000 pregnancies a year. Nearly 89% of teenage births occur outside of marriage. Of all women, 16% will be teen mothers. The largest increases in unintended pregnancies were found among women who were cohabiting, had lower education, and low income.
Abortion in the United States
A 2008 National Survey of Family Growth (NSFG) shows that rates of unintended pregnancy are highest among Blacks, Hispanics, and women with lower socio-economic status.
Anchor baby
There has been a growing trend, especially amongst Asian and African visitors from Hong Kong, China, South Korea, Taiwan and Nigeria to the United States, to make use of "Birth Hotels" to secure US citizenship for their child and leave open the possibility of future immigration by the parents to the United States. The U.S. government estimates that there were 7,462 births to foreign residents in 2008 while the Center for Immigration Studies estimates that 40,000 births are born to "birth tourists" annually. Pregnant women typically spend around $20,000 to stay in the facilities during their final months of pregnancy and an additional month to recuperate and await their new baby's U.S. passport. In some cases, the birth of a Canadian or American child to mainland Chinese parents is a means to circumvent the one-child policy in China; Hong Kong and the Northern Mariana Islands were also popular destinations before more restrictive local regulation impeded traffic. Some prospective mothers misrepresent their intentions of coming to the United States, a violation of U.S. immigration law; however, it is not illegal for a woman to come to the U.S. to give birth.
West Branch Area School District
Pennsylvania's birth rate has been declining for two decades. According to data from the Pennsylvania Department of Health, in 1990, the Commonwealth of Pennsylvania's birth rate was 171,053. In 2000, Pennsylvania's birth rate was 145,874. Finally in 2011, the State's birth rate declined further to 142,021. From 2000 to 2009, the number of babies born in rural counties declined 5 percent. Urban counties have also experienced a decline in the number of school aged children. From 2000-2010 urban Pennsylvania counties had a 3 percent decline in the number of residents under 18 years old. In 2010, there were 2.07 million residents, or 22 percent of the urban population, who were under age 18.
Teenage pregnancy in the United States
Black, Latina, and American Indian youth experience the highest rates of teenage pregnancy and childbirth. Studies show that Asians (23 per 1,000) and whites (43 per 1,000) have lower rates of pregnancy before the age of 20. The pregnancy rate among black teens decreased 48% between 1990 and 2008, more than the overall U.S. teen pregnancy rate declined during the same period (42%). The teen birth rate decline broken down by race in 2014 from 2013:
Hypertensive disease of pregnancy
Although the proportion of pregnancies with gestational hypertension and eclampsia has remained about the same in the U.S. over the past decade, the rate of preeclampsia has increased by nearly one-third. This increase is due in part to a rise in the numbers of older mothers and of multiple births, where preeclampsia occurs more frequently. For example, in 1998 birth rates among women ages 30 to 44 and the number of births to women ages 45 and older were at the highest levels in 3 decades, according to the National Center for Health Statistics. Furthermore, between 1980 and 1998, rates of twin births increased about 50 percent overall and 1,000 percent among women ages 45 to 49; rates of triplet and other higher-order multiple births jumped more than 400 percent overall, and 1,000 percent among women in their 40s.
Utah
Utah has the highest total birth rate and accordingly, the youngest population of any U.S. state. In 2010, the state's population was 50.2% male and 49.8% female.

Due in large part to the dramatic reduction in the risk of unwanted pregnancy engendered by the introduction of the Pill in 1960, not to mention the legalization of contraception nationwide by the Supreme Court decision in "Griswold v. Connecticut" in 1965, along with the steadily increasing acceptance of abortion and delayed marriages for career-minded young women influenced by second-wave feminism, or the chic rejection of the responsibilities of marriage altogether in favor of living together without raising a family, U.S. birthrates fell below replacement level starting in 1965 and remained depressed for almost 20 years; thus, children born during this period became known, at least in the popular press, as "baby busters" (as opposed to the "baby boomers" of the postwar years). Birthrates hit an all-time low during the post-OPEC recession in the mid-1970s.
Demographics of the world
Birth rates vary even within the same geographic areas. In Europe, as of July 2011, Ireland's birth rate is 16.5 per cent, which is 3.5 per cent higher than the next-ranked country, the UK. France has a birth rate of 12.8 per cent while Sweden is at 12.3 per cent. In July 2011, the UK's Office for National Statistics (ONS) announced a 2.4% increase in live births in the UK in 2010 alone. This is the highest birth rate in the UK in 40 years. By contrast, the birth rate in Germany is only 8.3 per 1,000, which is so low that both the UK and France, which have significantly smaller populations, produced more births in 2010. Birth rates also vary within the same geographic area, based on different demographic groups. For example, in April 2011, the U.S. CDC announced that the birth rate for women over the age of 40 in the U.S. rose between 2007 and 2009, while it fell among every other age group during the same time span. In August 2011, Taiwan's government announced that its birth rate declined in the previous year, despite the fact that it implemented a host of approaches to encourage its citizens to have babies.

Birth rate
Child custody laws, affecting fathers' parental rights over their children from birth until child custody ends at age 18, may have an effect on the birth rate. U.S. states strict in enforcing child support have up to 20 percent fewer unmarried births than states that are lax about getting unmarried fathers to pay, the researchers found. Moreover, according to the results, if all 50 states in the United States had done at least as well in their enforcement efforts as the state ranked fifth from the top, that would have led to a 20 percent reduction in out-of-wedlock births.
Birth rate
Birth rates ranging from 10–20 births per 1,000 are considered low, while rates from 40–50 births per 1,000 are considered high. There are problems associated with both extremes. High birth rates may stress government welfare and family programs. Additional problems faced by a country with a high birth rate include educating a growing number of children, creating jobs for these children when they enter the workforce, and dealing with the environmental impact of a large population. Low birth rates may stress the government to provide adequate senior welfare systems and stress families who must support the elders themselves. There will be fewer children (and a working-age population) to support an aging population.
Texas
For decades the infant mortality rate in Texas was higher than the nationwide rate but that gap has slowly closed. In 2017, the infant mortality rate in Texas was identical to the nationwide rate: 5.9 deaths per 1,000 live births. This rate is not identical across the state of Texas and studies have found significant disparities between zip codes. For example, the 76164 zip code has an infant mortality rate of 12.3 deaths per 1,000 live births while the neighboring 76107 zip code has a rate of 1.8 deaths per 1,000 live births. Additionally, Black families in Texas are disproportionately burdened by these rates. In 2015, the infant mortality rate for Black babies in Texas was 10.9 deaths per 1,000 births. These disparities can be explained by factors such as socioeconomic status, air pollution, and access to health care.
Human sex ratio
Several studies have examined human birth sex ratio data to determine if there is a natural relationship between the age of mother or father to the birth sex ratio. For example, Ruder has studied 1.67 million births in 33 states in the United States to discern effect of parent's age and birth sex ratios. Similarly, Jacobsen et al. have studied 0.82 million births in Denmark with the same goal. These scientists find that maternal age has no statistically significant role on human birth sex ratio. However, they report a significant effect of paternal age. Significantly more male babies were born per 1000 female babies to younger fathers than to older fathers. These studies suggest that social factors such as early marriage and quickly fertile couples may play a role in raising birth sex ratios in certain societies.
