Thhey estimate a 12-month rape rate of 1,270,000 among women and 1,267,000 among men (forced to penetrate).

Is this a correct reading of the figures, and thus sexual violence figures are actually more similar in the 12 month period than would be commonly assumed, or is this a misreading of the data? In which case, why are the lifetime numbers so different?
