It's generally higher than that depending on the data you use too. Most statistics you see are based on 1-2 year recidivism rates, so if they end up in prison at a later date then that's not included. For example, the UK keeps data of up to 9 years. It increases from 46% to 78% during that time period, so really almost 4 in 5 people return to crime.

Another thing to note is some base it on reconviction, instead of reimprosonment, which obfuscate the data again.
