Today, around 126 million women are believed to be “missing” around the world due to son preference and gender-biased sex selection (GBSS). Since the 1990s, some areas in the world have seen up to 25% more male birth than female birth (UNFPA Georgia). For example, the sex ratio at birth (SRB) increased from 107 in 1982 to 120 in 2005 in China [while the natural level is 102-106 males per 100 females] (Li, 2007).
