Registered sex offender counts for the 12 largest cities in Idaho, 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: Caldwell's rate is 19× Coeur d'Alene's.

Every Idaho 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 Idaho State Police Sex Offender Registry directly.
Offense-based with violent designation. Idaho registers adult sex offenders (most for life, with petition for release after 10 years in limited cases) and designates the most dangerous as Violent Sexual Predators. All adult registrants appear on the public site.
Offense-specific school rules. Idaho restricts offenders whose victims were minors from residing near or entering school grounds in many circumstances, but has no general statewide distance rule for all registrants.
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 Idaho:
As of July 2026, there are 5,867 registered sex offenders in Idaho — about 31.9 for every 10,000 residents, 33% above the national average. Counts change as offenders register, move, or are removed from the registry.
Boise has the most registered sex offenders in Idaho with 969. Raw counts track population, so the fairer comparison is per capita: adjusted for population, Caldwell has the highest rate among major cities at 72.6 per 10,000 residents, while Coeur d'Alene has the lowest at 3.8.

Public registry websites only show what the state chooses to publish. Idaho lists adult registrants publicly; juvenile registrants and sealed 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.
Offense-specific school rules. Idaho restricts offenders whose victims were minors from residing near or entering school grounds in many circumstances, but has no general statewide distance rule for all registrants. Address-level monitoring matters more than assumptions about "safe" neighborhoods.
Statistics on this page are compiled from official state registry records and refreshed monthly. This page was last updated in July 2026. Always verify individual records with the official state registry.
Yes. Predator Map Pro monitors up to 5 addresses daily and sends push and email alerts when a registered offender moves in nearby, a new offender registers, or someone moves away.
Yes. Registry information is public record under federal and state law (Megan's Law), and anyone may search it to protect themselves and their family. What the law prohibits is using registry information to harass, threaten, or commit a crime against a registrant — misuse can be prosecuted.

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.
