The data set contains descriptive information about the defendant, including age, sex, marital status, past criminal history, neighborhood environment, education, and employment history. Further information covers the source of the conviction, the offense category, number of counts in the indictment, maximum prison and maximum fine associated with the offense, duration and geographic spread of the offense, number of participants, number of persons arrested, number of businesses indicted, and spouse's employment. The defendant's socioeconomic status is measured using the Duncan index. The sample consists of a random sample of Federal crime offenders convicted of 1 of 10 statutory offenses, including securities fraud, antitrust violations, bribery, bank embezzlement, mail and wire fraud, tax fraud, false claims and statements, credit and lending institution fraud, postal theft, and postal forgery in 1976-78 in seven judicial districts representing metropolitan centers. The offenders are all individuals rather than groups or organizations. (Author abstract modified)
