Studies and government datasets consistently place false rape allegations in the single digits. In a Northeastern university study of 136 rape cases, David Lisak classified 5.9% as false. Police and prosecution reviews in the UK and the US often land in the same narrow range, even when investigation standards and definitions differ.
Key Takeaways
- In a study of 109 rape reports in a small Midwestern U.S. town from 1978-1987, 41% were found to be false after thorough investigation including polygraphs
- FBI Uniform Crime Reports from 1996 classified 8% of rape reports as "unfounded," often indicating false
- U.S. National Registry of Exonerations 1989-2018: 53% of wrongful convictions sexual assault cases involved false allegation

- Crown Prosecution Service (CPS) UK 2005-2013 data: 6.1% of 5,651 rape cases classified as no crime after review
False rape allegations are relatively rare, but they highlight the importance of careful, fair investigations.

Prosecutorial Data Interpretation
Across multiple UK prosecutorial datasets, the proportion of rape cases that end up no crimed, dropped, or treated as false or withdrawable clusters around a narrow band of roughly 5 to 7 percent in most years, with one key outlier showing 11 percent of 35 false allegation cases progressing to prosecution of the accuser in 2013, indicating that while false reporting often fails at the prosecutorial stage, it can still occasionally reach court outcomes.
