New Mexico has the highest jail-incarceration rate in the nation. That's according to a new report by the Prison Policy Initiative, a non-partisan non-profit that advocates for criminal-justice reform. In 2013, the latest year for which data was available, nearly 341 out of every 100,000 people in New Mexico were held in jails. The state with the second-highest rate was Georgia, with about 317 per 100,000 people. In contrast, Colorado’s rate was 221.
