Every Delaware 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 Delaware State Police Sex Offender Registry directly.
Three risk tiers. Delaware assigns Tier 1 (lowest) through Tier 3 (highest). Tier 2 and Tier 3 offenders appear on the public website; most Tier 1 offenders are excluded from public view, so the full registry is larger than the public search shows.
500-foot school rule. Delaware restricts certain offenders — generally those whose victims were children — from residing within 500 feet of a school. Supervision conditions can add further limits.
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.

Public registry websites only show what the state chooses to publish. Delaware's public site shows Tier 2 and Tier 3 offenders; most Tier 1 (lowest-risk) registrants aren't published. 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.
500-foot school rule. Delaware restricts certain offenders — generally those whose victims were children — from residing within 500 feet of a school. Supervision conditions can add further limits. 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.
