Registered sex offender counts for the 12 largest cities in Wisconsin, with each city's rate per 10,000 residents. Raw counts track population — the per-capita column is the fair comparison, and the spread is dramatic: Appleton's rate is 4× West Allis's.

Every Wisconsin city we track has its own page with neighborhood-level numbers, risk levels, and recent registrations:
Statewide numbers only tell you so much — what matters is who lives near your home, your kids' school, or the places your family spends time. The free Predator Map app searches any U.S. address and shows every registered offender around it on an interactive map, with photos, offense details, and registered addresses from official government registries. You can also search the official Wisconsin Sex Offender Registry (DOC) directly.
Corrections-maintained registry. Wisconsin's Department of Corrections registers offenders for 15 years or life depending on the offense and publishes registrants on the public site, with special-bulletin notifications for the most serious cases.
No statewide rule — a patchwork of local ordinances. Wisconsin has no statewide distance statute, but dozens of municipalities adopted their own residency ordinances (with varying buffers), so where registrants may live changes city to city.
Registration & verification. Registrants must keep their address, employment, and schooling current with the registry, and verify in person on a recurring schedule — more frequently for higher-risk or higher-tier registrants. Failure to register or verify is itself a crime and commonly appears as a listed offense on registry records.
Current risk-level breakdown in Wisconsin:
As of August 2026, there are 20,543 registered sex offenders in Wisconsin — about 34.9 for every 10,000 residents, 45% above the national average. Counts change as offenders register, move, or are removed from the registry.
Milwaukee has the most registered sex offenders in Wisconsin with 3,020. Raw counts track population, so the fairer comparison is per capita: adjusted for population, Appleton has the highest rate among major cities at 81.0 per 10,000 residents, while West Allis has the lowest at 22.5.
Use the free Predator Map app to search any Wisconsin address and see registered offenders around it on a map, with photos and offense details from official registry records. You can also search the official Wisconsin Sex Offender Registry (DOC) website directly.
Public registry websites only show what the state chooses to publish. Wisconsin publishes registrants on the DOC site; some juvenile and expired records don't appear. Statistics on this page are compiled from aggregated official registry records, so they can differ from — and often exceed — what a manual search of the public site returns.
No statewide rule — a patchwork of local ordinances. Wisconsin has no statewide distance statute, but dozens of municipalities adopted their own residency ordinances (with varying buffers), so where registrants may live changes city to city. Address-level monitoring matters more than assumptions about "safe" neighborhoods.

Methodology: Statistics are compiled from aggregated official state registry records and refreshed monthly. City figures count the city listed on each registry record. Per-capita rates use 2020 U.S. Census populations. Aggregated counts can exceed what public registry websites display because some classification levels are excluded from public searches. Figures are estimates and change daily as registries update — always verify individual records with the official state registry.
