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.
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.
