Where Idaho ranks
Idaho holds the 35th-largest count of registrants we index among the 56 US jurisdictions — just behind West Virginia (≈5,450) and ahead of New Jersey (≈4,540). Idaho's rate of 2.9 registrants indexed per 1,000 residents ranks 24th among the US jurisdictions with at least 1,000 indexed records, against a national average of about 4.7 per 1,000. Idaho's rate is higher than 2 of its 6 neighboring jurisdictions in the table and lower than 4. Absolute size and per-capita rate order the states very differently — the full rankings are on the count ranking and the per-capita ranking.
Housing status (national estimate). No per-state housing figure is published here, because our housing data is a national sample estimate: across 6,668 sampled records nationwide, 5.7% of registrants with a known housing status were homeless or had no fixed address as of August 2026. That figure describes the country, not Idaho — the breakdown is on the national statistics page.
Where Idaho’s registrants live
The largest local counts among the Idaho cities and counties we publish pages for, with the rate per 10,000 residents so places of different size compare fairly.
| County | Indexed | Per 10,000 |
|---|---|---|
| Ada County | ≈ 1,238 | 25 |
| Canyon County | ≈ 988 | 42.8 |
| Kootenai County | ≈ 372 | 21.7 |
What these Idaho numbers measure
Every figure on this page is a count of the registry records in our continuously updated index that carry a Idaho address, rounded to three significant figures and dated to August 2026. Rates divide that rounded count by the 2020 Census population, so they describe scale, not precision to the last person. Local counts cover the cities and counties we publish pages for, not every town in the state.
Registry sizes are not a direct measure of risk. States set their own rules on who must register, for how long, and which registrants are shown to the public, so two states with similar populations can carry very different counts. Use the comparison for context, and a search for any question about a specific person or address.
Idaho's registry publishes a full date of birth, so if you know the person's birthday a match can be confirmed precisely. With a common name, a matching date of birth is the fastest way to tell two people apart.
How to search Idaho’s registry
Idaho’s own public search is Idaho Sex Offender Registry (ISP), which covers Idaho only. A search here covers Idaho and every other US registry in one pass, returns photographs and the official record link for each result, and can be narrowed to a city, county or ZIP — or run outward from a street address.

How many registered sex offenders live in Idaho?
As of August 2026, we index about 5,360 sex-offender registry records in Idaho — the 35th-most of the 56 US jurisdictions. That is a count of the records in our continuously updated index, not Idaho's official figure: registries add, remove and amend records all the time, so the live answer for a specific person comes from a search, not a table.
How many sex offenders does Idaho have per capita?
About 2.9 registrants indexed per 1,000 residents, using the 2020 Census population as the denominator. Idaho's rate of 2.9 registrants indexed per 1,000 residents ranks 24th among the US jurisdictions with at least 1,000 indexed records, against a national average of about 4.7 per 1,000. A rate describes the size of a registry relative to population — jurisdictions differ in who must register, for how long, and which registrants they publish, so it is a scale comparison rather than a safety measure.
Which Idaho city has the most registered sex offenders?
Among the Idaho cities we publish local pages for, Boise has the most registrants we index, at about 942, followed by Nampa (about 535). Big cities lead on raw counts because they have more people; the per-10,000 column is the fairer comparison.
Which Idaho county has the most registered sex offenders?
Among the Idaho counties we publish pages for, Ada County has the most registrants we index, at about 1,238. Each county page breaks that figure down by city.
How does Idaho compare with neighboring states?
Idaho's rate is higher than 2 of its 6 neighboring jurisdictions in the table and lower than 4. Rates differ partly because states set different rules for who must register, for how long, and which registrants are shown publicly, so a neighbor comparison describes registry size relative to population rather than relative risk.
Where can I search Idaho's sex offender registry?
Idaho's own public search is Idaho Sex Offender Registry (ISP), which covers Idaho only. A search here covers Idaho and every other US registry at once, with photographs and links to each official record, and can be narrowed to a Idaho city, county or ZIP.
Are these Idaho's official registry numbers?
No — they are approximate counts of the registrants we index for Idaho, rounded to three significant figures and dated to August 2026. Jurisdictions count different things (people, registrations, addresses) and publish on their own terms, so no single official national table exists. For a legal or research purpose that requires Idaho's official figure, request it from the state registry authority.
Registry data is not a consumer report, and decisions made on it are regulated in that use.
