A few people here know me in real life, and know the area I work in. I have no idea if this average number is correct. But from my limited perspective sure there is more reporting, more investigation, more services call on, etc. today than in the past. That does not mean less happened in the past. There are MANY cases reported in the past years of historical abuse in sports/hobby, educational, religious, settings .. these would not have been reported historically (or if reported in Ireland, would not have been investigated).
In all my years, I have never been involved a case where the suspect was a woman (but I am aware of a small few).
I am no longer surprised by all this (I used to be).
