Perceived
Public perception of child sexual abuse risk is shaped by two contradictory forces. "Stranger danger" campaigns from the 1980s onward anchored parental anxiety on a relatively rare scenario — abduction and abuse by an unknown person — while simultaneously obscuring the far more common reality that the vast majority of perpetrators are known and trusted adults. Most parents assess their own child's risk as low because they mentally screen for the stranger archetype and find it absent from their daily environment. The actual epidemiology — concentrated among family members, coaches, clergy, and other authority figures — is widely known in the abstract but rarely internalized as a personal probability.

~25% of girls and ~5% of boys experience sexual abuse before age 18 (CDC)
US children, CDC retrospective adult surveys and child maltreatment data
Show derivation
The CDC reports that at least 1 in 4 girls and 1 in 20 boys experience child sexual abuse in the United States. Using approximate midpoint estimates: girls 25%, boys 5%. Combined-sex weighted average (assuming ~49% female, ~51% male birth ratio in the relevant child population): 0.49 × 0.25 + 0.51 × 0.05 ≈ 0.148. The lifetime_us_adult field carries the childhood prevalence figure for schema compatibility; this is a pre-18 measure, not an adult-lifetime annual-rate extrapolation. A 2009 meta-analysis of 65 studies across 22 countries (cited by Barth et al. 2013) found global prevalence of 19.7% for girls and 7.9% for boys, broadly consistent with US figures. Uncertainty band: low end uses the narrowest contact-only definitions in conservative studies (~8%; e.g., Pereda et al. 2009 global male-only floor combined with narrow US female estimates); high end reflects broader definitions and underreporting adjustments (~25%).

The CDC's "1 in 4 girls and 1 in 20 boys" figures are derived primarily from retrospective adult surveys (NISVS, ACE study) in which adults report childhood experiences. These capture more than official child-protection reports, which record only cases that come to agency attention — estimated at a fraction of actual prevalence. The 90% known-perpetrator figure means that "stranger danger" frameworks miss the vast majority of risk; the most common perpetrators are family members, family friends, babysitters, coaches, and other authority figures with legitimate access to children. Prevalence varies by demographic factors: children with disabilities face 2-3x higher rates, and certain racial/ethnic groups show elevated risk in US data, though these differences may partly reflect differential disclosure and reporting patterns. The long-term health consequences are well-documented — CSA is associated with elevated rates of depression, PTSD, substance abuse, and revictimization in adulthood — making the childhood prevalence figure epidemiologically significant far beyond the immediate harm.

The CDC estimates that at least 1 in 4 girls and 1 in 20 boys in the United States experience child sexual abuse before age 18. These figures are drawn primarily from retrospective adult surveys — notably the National Intimate Partner and Sexual Violence Survey and the Adverse Childhood Experiences (ACE) study — in which adults report childhood experiences of sexual abuse. The retrospective methodology captures substantially more than official child-protection records, which reflect only cases that come to agency attention. The CDC’s own Report to Congress estimates that approximately 3.7 million children are exposed to some form of sexual abuse each year, and only about 38% of child victims ever disclose. A 2009 meta-analysis of 65 studies across 22 countries found global prevalence of 19.7% for girls and 7.9% for boys, broadly consistent with the US figures and confirming that this is not a uniquely American phenomenon.
The most consequential finding in the epidemiological literature is not the prevalence itself but the perpetrator profile. Approximately 90% of children who experience sexual abuse know their abuser — the perpetrator is a family member, family friend, coach, teacher, clergy member, or other trusted adult with legitimate access to the child. The “stranger danger” framework that dominated child-safety messaging for decades and continues to shape parental risk perception is, by the numbers, a response to roughly 10% of actual cases. This mismatch between perceived and actual risk vectors is not merely an academic concern: it directs parental vigilance outward (toward public spaces, unknown adults, online strangers) while leaving the statistically dominant risk environment — the child’s own social circle — comparatively unmonitored.
The combined-sex weighted average of roughly 1 in 7 US children experiencing sexual abuse before adulthood places this among the highest-prevalence crime entries in this dataset. The consequences extend well beyond childhood: the ACE study and subsequent longitudinal research have established strong dose-response relationships between childhood sexual abuse and adult outcomes including depression, post-traumatic stress disorder, substance use disorders, chronic pain conditions, and elevated risk of revictimization. Children with disabilities face 2-3 times higher rates of sexual abuse than their non-disabled peers, a disparity that receives relatively little public attention. The underreporting problem is structural and severe — most victims do not disclose during childhood, and many do not recognize or label their experiences as abuse until adulthood, which is precisely why retrospective surveys yield higher prevalence than contemporaneous reporting systems.

- Annual incidence figure from CDC's Congressional report. 3.7 million / ~73 million US children = ~5.1% annual incidence. Over an 18-year childhood: 1 − (1 − 0.051)^18 ≈ 0.61 if events were independent, but the survey-based lifetime prevalence of ~16-25% indicates substantial overlap (same children victimized repeatedly) and definitional differences between annual incidence and lifetime prevalence measures. The 38% disclosure rate underscores the underreporting problem.

Meta-analysis of 65 studies in 22 countries: 19.7% of females and 7.9% of males experienced CSA before age 18- Excerpt
“"A meta-analysis conducted in the year 2009 analyzed 65 studies in 22 countries and estimated an overall international figure. An estimated 7.9% of males and 19.7% of females universally faced sexual abuse before the age of 18 years." ”

- Global meta-analytic estimate (Pereda et al. 2009, cited by Barth et al. 2013) corroborating the US-specific CDC figures. The global female prevalence of 19.7% is close to the CDC's 25% US figure; the male prevalence of 7.9% sits above the CDC's 5% (1 in 20), likely reflecting broader definitions in the international literature. Both streams confirm that official records severely undercount actual prevalence.
