In France alone. From a below article about a priest admitting to one abuse of a 14-year old girl (with no details, I'm sure he denies the worst parts of any accusation as do all assholes like him)
The broad study released last year by an independent commission estimated that some 330,000 children were sexually abused over 70 years by priests or other church-related figures in France.
The tally included an estimated 216,000 people abused by priests and other clerics, and the rest by church figures such as scout leaders and camp counselors. The estimates were based on broader research by France’s National Institute of Health and Medical Research into sexual abuse of children.
