California has the most registered sex offenders of any state, with roughly 96,000 people on its registry as of late 2025. That is a raw-total ranking, and it mostly tracks population size. By a different and arguably more useful measure — registrants per 100,000 residents — Oregon leads the country by a wide margin, with about 795 per 100,000. The question of which state has the most sex offenders has two honest answers depending on which number you want.
States With the Largest Registries by Total Count
California’s registry carried approximately 96,000 people as of December 2025. Not all of them lived in neighborhoods. About 74,400 resided in the community, roughly 20,700 were incarcerated in state prisons, and just under 1,000 were held in civil commitment facilities.1California Sex Offender Management Board. Year End Report 2025 The publicly searchable Megan’s Law website shows only those living in the community, which is why its visible count runs lower than the full registry total.2Megan’s Law Website. Statistics
Florida ranks next in sheer size. Its registry listed more than 86,200 offenders and predators as of October 2024, but only about 30,000 of those individuals were living in Florida communities at the time. The rest were incarcerated, deported, or otherwise not residing freely in the state.3Florida Office of Program Policy Analysis and Government Accountability. Sex Offender Registration and Monitoring Triennial Review Texas also maintains one of the nation’s largest registries, consistent with its position as the second most populous state, though the Texas Department of Public Safety does not publish a single readily available statewide count in the same format California and Florida do.
The caveat with raw totals: more people means more of everything, including convictions and registrations. A state at the top of this list is not automatically less safe. It usually just has more residents.
States With the Highest Rates Per Capita
Oregon has held the top spot for over a decade. As of early 2025, the state had about 795 registrants per 100,000 residents.4Oregon Knowledge Bank. Sex Offender Monitoring and Compliance The gap between Oregon and every other state is substantial, and the main driver is Oregon’s unusually broad registration requirements, which capture a wider range of offenses than most other jurisdictions.
Arkansas ranks second, with roughly 645 registrants per 100,000 residents and a total registry of about 20,400 people as of mid-2026.5Arkansas Department of Public Safety. Registered Sex Offenders After those two outliers, the numbers drop. Alaska, South Dakota, and Wisconsin fill out the top five, each sitting in the 460 to 480 range per 100,000.
A high per capita rate does not automatically translate to more criminal activity. It often reflects broader registration criteria, more aggressive prosecution, or policies that keep people on the registry longer. States with narrower definitions of registerable offenses, such as New Jersey and Massachusetts, sit near the bottom of per capita rankings despite having large, dense populations.
Why Registry Counts Vary So Much Between States
Federal law sets a minimum standard for sex offender registration, but each state can go beyond it. Three design choices drive most of the differences between state totals: which offenses trigger registration, how long people stay on the list, and whether juvenile adjudications are counted.
Some states require registration for offenses that other states handle outside the registry system entirely, including public urination, consensual acts between teenagers close in age, and certain non-contact crimes. When a state casts a wider net, its registry inflates without any corresponding increase in serious offenses. Oregon’s position at the top of the per capita rankings is largely a product of this. The state requires registration for conduct that some jurisdictions treat as a non-registerable misdemeanor.
Duration matters too. States where most registrants face lifetime obligations accumulate names faster than states where lower-level offenders cycle off after 10 or 15 years. A state that quietly removes people as they complete their required periods will show a smaller count than a neighboring state with identical crime rates but longer registration terms.
Juvenile adjudications are the third variable. Under federal guidelines, only juveniles who were at least 14 at the time of the offense and adjudicated for conduct equivalent to aggravated sexual abuse can be required to register.6Office of Justice Programs. Juvenile Sex Offender Registration Under SORNA Federal supplemental guidelines leave states discretion over whether to post juvenile registrants on public websites, and some states require registration for a broader set of juvenile offenses than the federal minimum.
Classification systems add another layer. Not every state has adopted the federal SORNA tier structure, which sorts registrants by offense severity. Some states use their own schemes based on individual risk assessments instead.7Office of the Law Revision Counsel. 34 USC 20911 – Relevant Definitions A person classified as a lower-level offender in one state can face stricter requirements, and a longer stay on the registry, after moving somewhere else.
Comparing the Two Measures
Total counts answer “where do the most registrants live?” Per capita rates answer “how heavily does this state use its registry?” The two questions pull in different directions. California tops the raw list because it has 39 million residents. Oregon tops the per capita list because its laws define registerable conduct more broadly. Neither number, on its own, tells you how many serious offenses occurred in a given state last year or how much risk a resident actually faces.
If you are comparing states as a place to live, work, or raise a family, the per capita rate is the fairer comparison. If you want to know where the largest absolute population of registrants sits, total count is the measure. Both are legitimate; they just answer different questions.
How to Check the Registry for a Specific Location
The Dru Sjodin National Sex Offender Public Website, at NSOPW.gov, is the federal government’s centralized search tool. It pulls data from the registries of all 50 states, the District of Columbia, U.S. territories, and participating tribal jurisdictions.8Dru Sjodin National Sex Offender Public Website. About NSOPW The site does not host the data itself. It queries each jurisdiction’s database in real time, which means results are only as current as the state registry behind them.
You can search by name, ZIP code, street address, city, or county. Name searches work nationwide or within a single state. Address-based searches let you set a radius of one to three miles to see registrants near a specific location.9Dru Sjodin National Sex Offender Public Website. Search Public Sex Offender Registries Results typically include a photograph, physical description, offense information, and compliance status, though the level of detail varies by state. Some jurisdictions share full address data; others display only a ZIP code.
No registry captures every risk. People with no criminal record do not appear, and registrants who have absconded or failed to update their address may show up at outdated locations. The registry is one tool for situational awareness, not a complete picture.
