Recidivism 102—Sexual Recidivism Stats by Various Studies – Compiled by Derek W. Logue of OnceFallen.com

This report is a supplement to Once Fallen’s Recidivism 101 article. This chart only consists of raw data contained within the reports.

Recidivism is not as easy to define as people assume. We obviously think of a sex offender recommitting a sex crime, but some studies may include technical violations, Failure to Register, or non-sex offenses in recidivism numbers. There are a number of studies out there, and all use different standards. For the sake of simplicity, I am focusing on two of the most common standards—Re-arrest rates and reconviction rates. Even within this narrow definition, however, there is no universal standard by which these studies follow. Many studies after 2003 have tried emulating the US Department of Justice survey, but not all follow the pattern.

Some studies may be repeated here because they break down rates into shorter and longer periods, or some studies may be follow-ups to earlier recidivism studies. Most studies are limited to between 3 years and 5 years (which is fine since most recidivists commit new crimes within the first three years of release). Some studies used inmates released during multiple years, further complicating recidivism rates; The Minnesota-B study used 2007 as the cutoff date regardless of whether the sample was released in 2002 or 1990. That means some people were in the sample longer than others. Some recidivism data may overlap; some studies, for example, may use the same state recidivism data that was collected in another study.

Unlike other attempts to summarize recidivism studies, I have limited this chart to American re-offense studies. There are a number of reasons for choosing only American studies, but primarily because policy issues in the USA tend to regulate far more sexual activity than in other countries, even those with sex offender registry laws like Canada or the UK.

Under re-arrest and re-conviction rate headings, the numbers in parentheses are actual number of recidivists when listed in the study. Unfortunately not all studies gave the actual numbers, just the percentages who reoffended.

A number of studies here are excluded primarily because they did not cover re-arrest/ reconviction rates, are studies from other countries, or were too vague to determine the numbers needed here. This is thus not exhaustive, but is comprehensive of those American Recidivism studies with re-arrest or reconviction stats.

*Indiana, NY state and Ohio studies used reincarceration as the recidivism standard. Recidivism rates can include sex-related technical violations, but these numbers do not reflect technical violations.
**The 2019 BJS study omitted actual numbers in favor of percentages, only adding that only half of arrests led to a conviction; in addition, the BJS omitted inmates released who had not been currently incarcerated for a sexual offense but had a sex offense in their criminal history, inflating the rearrest numbers to 7.7%. This is discussed in full detail in the OnceFallen article on the “UNIQUE THREAT MYTH“

    rates were the same between the two groups (3.8% and 3.9%, respectively). Thus, combining the total numbers does not influence the results.
