Registered sex offenders by state
All 56 US jurisdictions: records indexed, 2020 Census population, rate per 1,000 residents, as-of date.
Registered sex offenders by city
Every published city figure: records indexed with an address in the city, population, rate per 1,000 residents.
Figures are counts of records we index, dated per row — approximate by nature and not official state counts. Aggregates only: no individual records appear in these files. For person-level search, use the dashboard or the API — or see how the top registry APIs compare. Not a consumer report; not for FCRA-governed decisions.
