White House claims that one in five women will be sexually assaulted while in college, and that just 12 percent report the crime, cannot both be true, according to American Enterprise scholar Mark J. Perry.

In January, a White House task force made the two claims, but Perry — who is also an economics professor at the University of Michigan in Flint — did the math using sexual assault statistics from Ohio State University and found a major discrepancy. Perry originally noted this discrepancy in May, but has updated his statistics since OSU released its 2013 numbers.
