INFANTICIDE

According to the Webster's Ninth New Collegiate Dictionary: Infanticide - the killing of an infant.

According to The Society for the Prevention of Infanticide In 1978, Laila Williamson, an anthropologist of the American Museum of Natural History, summarized the data she had collected on the prevalence of infanticide among tribal and civilized societies from a variety of sources in the scientific and historical literature. Her conclusion was startlingly blunt:

Infanticide has been practiced on every continent and by people on every level of cultural complexity, from hunters and gatherers to high civilization, including our own ancestors. Rather than being an exception, then, it has been the rule.

According to the Bureau of Justice Statistics 555 children under the age of 5 were killed in America in the year 2005. The younger the child the greater the risk of Infanticide as you can see by the chart below.
