|Recidivism 102—Sexual Recidivism Stats by Various Studies – Compiled by Once Fallen
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

*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.

supervision and treatment of sex offenders. I’d also like to add the year average came from people followed between three and sixteen years.

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

they could combine five year recidivism rates for both groups but could only get 10 year rates from the 1999-2000 group of 250.
