Recently released by the US Department of Justice's Bureau of Justice Statistics, this report enumerates the more than 3.9 million men and women on probation or parole in the US at the end of 1997. The report lists the total number of parolees and probationers by region and state, scrutinizes the demographic characteristics of this record-breaking population, and compares the results with the totals from 1990 and 1996. Statistical breakdowns include sex, race, type of offense, number of entries, number of exits, rate of recidivism, and length of sentence. Comparative tables also list the ten states with the highest and the lowest supervised populations, with an additional column identifying the ten states with the greatest percentage increase.
