93% of victims under 18 know their abuser.
Sure there's 7% thats not, but a significant supermajority is family/friends. 59% were acquaintances, and 34% are family.
Edit: seriously, -1 cause I link to actual facts, rather than shitty emotional outbursts? Family and friends of family have always been the major list of suspects for child sex abuse. They're the ones who have time and access.
But somehow linking to cited facts is -1 central. Sigh.
