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.
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.
