Registered sex offender counts for the 11 largest cities in Maine, with each city's rate per 10,000 residents.

Every Maine 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 Maine Sex Offender Registry (State Bureau of Identification) directly.
10-year and lifetime registrants. Maine registers offenders for 10 years or life depending on the offense and prior record, and publishes registrants on the public site without a risk-level system.
No statewide residency restriction. Maine has no statewide distance rule; municipalities may adopt limited local ordinances (up to 750 feet from schools and similar), so rules vary town to town.
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 Maine:
As of July 2026, there are 3,212 registered sex offenders in Maine — about 23.6 for every 10,000 residents, 2% below the national average. Counts change as offenders register, move, or are removed from the registry.
Portland has the most registered sex offenders in Maine with 195. Raw counts track population, so the fairer comparison is per capita: adjusted for population, Bangor has the highest rate among major cities at 50.7 per 10,000 residents, while South Portland has the lowest at 10.6.

Public registry websites only show what the state chooses to publish. Maine publishes registrants currently under a registration duty; records roll off as 10-year terms expire. 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 residency restriction. Maine has no statewide distance rule; municipalities may adopt limited local ordinances (up to 750 feet from schools and similar), so rules vary town to town. 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.
