A sampling of Michigan parolees was done to cross-validate the Iowa model for assessing risk of offending while on parole.
Abstract
A random sample of 676 male parolees in Michigan was selected from the population of 4,084 inmates released on parole by the Michigan Parole Department during the calendar year 1980. The follow-up period was over two and one-half years. Different measures of predictors such as prior criminal history, current offense, substance abuse history, age, and recidivism on parole were collected. The data is available in two, card image computer files. The first file contains information on parolees such as demographic characteristics, drug use history, prior criminal history, risk scores, and parole history. The second file includes parolees' detailed criminal histories including the total number of violent and nonviolent felony arrests and dates and charges and dispositions of each arrest for a maximum of eight arrests. The booklet describes the collection methods for each file, how they were compiled, and what is in each in detail.
