document: CDC : Drop in U.S. Birth Rates Biggest in 30 Years Less women are having babies in the U.S. , according to a new report by the Centers for Disease Control and Prevention . The number of births fell 4 percent from 2007 to 2009 , which is the biggest drop for any two-year period in 30 years . Fertility rates for women between the ages of 15 to 44 - also known as the childbearing years - also fell during this same time frame . However , analysts say declines in the early 20th century and in the 1960s and early 1970s were much more dramatic than those currently reported by the CDC . Key findings from the report : - From 2007 through 2009 , birth rates for women aged 15-44 -LRB- fertility rates -RRB- fell for most states and nearly all major population subgroups . - Birth rates declined for all women under age 40 with some of the largest decreases for women in their peak childbearing years . - Fertility rates dropped for all major racial and Hispanic groups with the largest declines among Hispanic women . - Birth rates by live-birth order also fell with the largest declines for third-order births and progressively smaller declines for second - and first-order births . - Fertility rates decreased or were unchanged in every state and the District of Columbia with the largest declines among western and southeastern states .
