US sex offender registry data, free to download.
Aggregate counts by state and city with per-1,000-resident rates, as CSV — the same figures our statistics page publishes, in a shape you can chart, join and cite. Free for research and reporting with attribution to Offendersearch (link to this page or the statistics page).
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. Not a consumer report; not for FCRA-governed decisions.
