"According to the 2010 Uniform Crime Report, released by the Federal Bureau of Investigation last week, there were 84,767 sexual assaults in the United States last year, a 5 percent drop from 2009...The definition of rape used by the F.B.I. — “the carnal knowledge of a female, forcibly and against her will” — was written more than 80 years ago. The yearly report on violent crime, which uses data provided voluntarily by the nation’s 18,000 law enforcement agencies, is widely cited as an indicator of national crime trends. But that definition, critics say, does not take into account sexual-assault cases that involve anal or oral penetration or penetration with an object, cases where the victims were drugged or under the influence of alcohol or cases with male victims. As a result, many sexual assaults are not counted as rapes in the yearly federal accounting."
