"A Perspective on Clergy Sexual Abuse" by Catholic Dr. Thomas Plante of the Catholic Santa Clara University and volunteer clinical associate professor at Stanford University states that "approximately 4% of priests during the past half century (and mostly in the 1960s and 1970s) have had a sexual experience with a minor" which "is consistent with male clergy from other religious traditions and is significantly lower than the general adult male population which may double these numbers".Plante's article was based on a study done by John Jay College.
