About these numbers#
Counts are records listed on public state sex offender registries, matched to a ZIP code by the address on the record (snapshot of August 13, 2026). One person can appear at more than one address, some records carry only a ZIP code or a city, and people in custody may be listed at a facility. Names, photos and addresses are never shown on these pages; they stay on the official registries and in the Warden map.
