[specialist]

I too would like to know.

Half the males of my cohort (siblings, cousins) were victim of one uncle. Only surfaced a decade later.

One of my siblings was later victim of a priest. Escaped a bad situation only to end up in hell.

I somehow avoided my uncle. Though later, in 4th grade (10yo) a teacher groped me. And much later that creepy too-friendly teacher in middle school was busted (preying on females).

So just from my own anecdata, I assume it much higher, every where, than people acknowledge.
