Daughter
In the United States, the birth rate is 105 sons to 100 daughters which has been the natural birth rate since the 18th century. About 80 percent of prospective adoptive parents from the US will choose a girl over a boy. In fertility clinics that enable sex preferences, daughters are usually preferred over sons. In the traditions of various Abrahamic religions, Luluwa is regarded as the first daughter to have ever existed.
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.
