Prevalence of sexual violence against children and age at first exposure: a global analysis by location, age, and sex (1990–2023)

Measuring sexual violence against children (SVAC) is vital to prevention and advocacy efforts, yet existing prevalence studies present estimates for few countries. Here we estimate the prevalence of SVAC for 204 countries by age and sex, from 1990 to 2023, and also report the age at which young survivors of lifetime sexual violence first experienced sexual violence.

We reviewed publicly available repositories for data on the prevalence of SVAC. To harmonise heterogeneity in the identified input data, we adjusted for alternative case definitions of SVAC and differential disclosure by survey mode. We then used a spatiotemporal Gaussian process regression to estimate a full time series of exposure to SVAC for each age-sex-country combination. We accounted for uncertainty in the underlying data and modelling processes. We also analysed the age at which adolescent and young adult survivors of lifetime sexual violence first experienced this type of violence by sex, data source, and world region.
