As many as 20,000 children endured sexual abuse at Dutch Catholic institutions over the past 65 years, and church officials failed to adequately address it or help the victims, according to a long-awaited investigative report released Friday.

Based on a survey of 34,000 people, the report estimated that 1 in 10 Dutch children suffered some form of sexual abuse — a figure that rose to 1 in 5 among children who spent part of their youth in an institution such as a boarding school or children’s home, whether Catholic or not.
