Evidence is uneven
Available research has often focused on Roman Catholic clergy in particular countries and periods. Comparable evidence for other Christian denominations and other religions is more limited. Reported figures can be affected by delayed disclosure, incomplete records, changing definitions and differences in reporting systems.
For that reason, no single percentage can describe clergy abuse everywhere. A responsible account distinguishes allegations, documented findings, civil settlements, criminal convictions and population estimates.
Who may be affected?
Children and adolescents have been among those who reported abuse. Survivors may disclose years later, and many never report what happened. Abuse can involve misuse of authority, grooming, secrecy, threats or institutional pressure as well as physical acts.
Responsibility rests with the adult who abuses power and with institutions that fail to protect, investigate or respond appropriately—not with children or survivors.
A note on language
Older sources sometimes use clinical or disputed labels in ways that blur important distinctions. This page uses “sexual abuse of children and young people” when describing harm, and reserves legal conclusions for competent investigations or courts.
