Hi there!
The following excerpt is per the USSC:
“This report provides a broad overview of key findings from the United States Sentencing Commission’s study of recidivism of federal offenders. The Commission studied offenders who were either released from federal prison after serving a sentence of imprisonment or placed on a term of probation in 2005. Nearly half (49.3%) of such offenders were rearrested within eight years for either a new crime or for some other violation of the condition of their probation or release conditions. This report discusses the Commission’s recidivism research project and provides many additional findings from that project. In the future, the Commission will release additional publications discussing specific topics concerning recidivism of federal offenders. (March 2016).”
The above quote is from the following link, which also contains the (full-text) comprehensive report regarding federal recidivism rates:
