Every New Hampshire 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 New Hampshire Registration of Criminal Offenders (DOS) directly.
Tiered registration. New Hampshire registers offenders for 10 years or life by tier. The public list focuses on offenders against children and the most serious offenses; other registrants are known to police but not published, so the full registry is larger than the public list.
No statewide residency restriction. New Hampshire has no statewide distance rule, and courts struck down local residency ordinances — restrictions come only through supervision conditions.
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 New Hampshire:
As of July 2026, there are 2,634 registered sex offenders in New Hampshire — about 19.1 for every 10,000 residents, 20% below the national average. Counts change as offenders register, move, or are removed from the registry.
Manchester has the most registered sex offenders in New Hampshire with 586. Raw counts track population, so the fairer comparison is per capita: adjusted for population, Concord has the highest rate among major cities at 53.2 per 10,000 residents, while Portsmouth has the lowest at 8.2.

Public registry websites only show what the state chooses to publish. New Hampshire's public list focuses on offenders against children; other registrants don't appear in a public search. 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. New Hampshire has no statewide distance rule, and courts struck down local residency ordinances — restrictions come only through supervision conditions. 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.
