A two-stage stratified cluster sampling design was
employed. At the first stage, 344 counties were selected from the
3,195 total counties in the nation. At the second stage, a systematic
sample of felons sentenced for murder/non-negligent manslaughter,
rape, robbery, aggravated assault, burglary, felony larceny/motor
vehicle theft, drug trafficking, and other offenses were selected from
each county's official records.
