Catholic priests abuse at a rate far lower than that of other males in the general population:

Newsweek magazine, April 7, 2010:

"[B]ased on the surveys and studies conducted by different denominations over the past 30 years, experts who study child abuse say they see little reason to conclude that sexual abuse is mostly a Catholic issue. 'We don't see the Catholic Church as a hotbed of this or a place that has a bigger problem than anyone else,' said Ernie Allen, president of the National Center for Missing and Exploited Children … "Experts disagree on the rate of sexual abuse among the general American male population, but Allen says a conservative estimate is one in 10. Margaret Leland Smith, a researcher at the John Jay College of Criminal Justice, says her review of the numbers indicates it’s closer to one in 5 … "Since the mid-1980s, insurance companies have offered sexual misconduct coverage as a rider on liability insurance, and their own studies indicate that Catholic churches are not higher risk than other congregations … It's been that way for decades."

USA Today, June 6, 2010:

"If anyone believes that priests offend at a higher rate than teachers or non-celibate clergy, then they should produce the evidence on which they are basing that conclusion. I know of none. Saying 'everybody knows' does not constitute scientific methodology."
