It is likely that the abuser priests are also older, given the reality that a significant number of known abusers from incidents that happened 30 + years ago.  What it requires is very good supervision and safety plans for any abuser housed with non-abusers. It is better to house them somewhere, rather than turning them loose in the community which is what many, if not most dioceses do. Religious orders tend to keep their men in their religious community which provides stability and restrictions and day-to-day supervision. No perfect answers if there is not a conviction and prison sentence.
