Demographics
Slightly more boys are born than girls (in the US this ratio is about 105 boys born for every 100 girls), but girls are slightly less likely to die than boys, during childhood, so that the ratio for under 15 years of age is 104 boys for every 100 girls. Since the 18th century the human sex ratio has been observed as about 1,050 boys for every 1,000 girls born and sex selection on the part of parents further lessens the number of female births.
While patriarchal beliefs have led to female infanticide (the killing of female infants) since ancient times, it is a persistent practice in some regions of the world today. It is a significant problem in India and China in particular. The United Nations Population Fund (UNFPA) State of the World Population Report indicates that these practices, combined with neglect, have resulted in at least 60 million "missing" girls in Asia. Large numbers of adult women are absent from the population in some regions, a consequence of female infanticide during recent decades.
