Americans generally have one chance in 133 of being murdered over their lifetimes, according to the Government's first study of the risk of violent crime.

The study by the Bureau of Justice Statistics also concluded that about six million Americans, roughly 3 percent of those over 12, would become a victim of robbery, rape or other assault in a given year.

The report said that over their lifetimes, black men have a 1-in-21 chance of being murdered; white men have a 1-in-131 chance; white women a 1-in-369 chance and black women a 1-in-104 chance.

The assessment of murder risk was based on an analysis of reports submitted by coroners and medical examiners to the National Center for Crime Statistics in 1982.
