Registered sex offender counts for the 12 largest cities in Ohio, with each city's rate per 10,000 residents.

Every Ohio 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 Ohio eSORN Sex Offender Registry (Attorney General) directly.
Tier I–III registration. Ohio was the first state to adopt the federal Adam Walsh Act tiers: Tier I (15 years), Tier II (25 years), Tier III (lifetime with 90-day verification). County sheriffs maintain eSORN; Tier III and many Tier II records appear in public searches while some Tier I records are disclosed more narrowly.
1,000-foot school rule. Ohio bars registrants from establishing a residence within 1,000 feet of a school (with childcare and preschool included in many cases); enforcement details have been shaped by court rulings on retroactivity.
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 Ohio:
As of July 2026, there are 28,399 registered sex offenders in Ohio — about 24.1 for every 10,000 residents, right at the national average. Counts change as offenders register, move, or are removed from the registry.
Cleveland has the most registered sex offenders in Ohio with 2,945. Raw counts track population, so the fairer comparison is per capita: adjusted for population, Dayton has the highest rate among major cities at 94.7 per 10,000 residents, while Parma has the lowest at 17.8.

Public registry websites only show what the state chooses to publish. Ohio's public searches emphasize Tier II and Tier III offenders; some Tier I records are only disclosed to those who request notification. 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.
1,000-foot school rule. Ohio bars registrants from establishing a residence within 1,000 feet of a school (with childcare and preschool included in many cases); enforcement details have been shaped by court rulings on retroactivity. Address-level monitoring matters more than assumptions about "safe" neighborhoods.
Ohio assigns Tier I (15-year registration, annual verification), Tier II (25-year, semi-annual), and Tier III (lifetime, every 90 days) based on the offense of conviction. There are currently 64 registrants at the highest classification in Ohio.

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.
