If that's an establish figured, it should be easy to find.
While I just went through some (including a bunch on Quora), I found none suggesting this.
Doesn't mean that's the case, as I was rushing, but the stats referred to suggested pretty much the same, save for a skewing in gender more commonly targeted in different circles, access obviously being a factor in terms of Altar Boys, etc.
One Quora post stated the average was a rate of 5 - 6% both with Catholic and everyone else, but that the rates in the Catholic system has been reduced to 1% with reforms since 2002. As I had not verified those numbers, I didn't mention it before, but implementing changes to reduce incidents does make sense given the attention and outcry as well as arrests and lawsuits.
I've brought the issue up with you before, and numbers with other Christian denominations and other religions may seem lesser simply because we're not dealing with large behemoths with extensive bookkeeping going back millenia.
Some, like Amish or Native Americans, treat these as internal matters, and numbers are largely swept under the rug. Other societies, like in the Middle East, may treat it as a crime - committed by the VICTIM who, if female, must marry the rapist, and if male, gets executed. You can be sure that in a society that claims if you are not under family supervision you are "asking for it," the number of incidents will make all others look like quantum physics submersed in a roiling sea.
