Read the fine print for the US data, however, and the FBI’s definition of rape was significantly expanded a decade ago.
Statistica offers no such clarification for the UK data, but their rise began in the same year—and I wonder if something similar also occurred there.
Remark deserves to be elaborated on. Are you perhaps referring to "date rape," sex occurring in a state of intoxication, or what?
I suspect that a disaggregation of the English/Welsh date according to ethnic background / migration status would prove very enlightening, and make any discussion of "definition-changes" moot.
