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
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".
