Are more women now reporting sexual assaults?

Or are there actually more sexual assaults?

A combination?

WNYC wrote: "Groping attacks are unfortunately very, very common," said Suzanne Goldberg, director of Columbia University’s Center for Gender and Sexuality Law. "I think it is unlikely that this recent spade of attacks is terribly out of the ordinary. Instead there was some initial reporting and strong media coverage and that has led to more reporting."
