Female infanticide has been practiced throughout history on every continent by both tribal and civilized societies. While poverty and population control have contributed to the practice, a bias against females in patriarchal societies is a major underlying cause. Historically, female infanticide was common in Arabia, India, China, and some Western societies prior to legal bans. Today it remains a significant problem in parts of Asia, where sex-selective abortion and neglect have resulted in millions of missing women. Prohibitions against the practice in major religions like Islam, Judaism, and Christianity did not always prevent it from occurring socially.
