In the individual file (Part 1), the sequence id numbers range from 1 to 11,172, then skip to 20,000 and range to 20,131. In the offense file (Part 2), the sequence id numbers range from 1 to 3,534, then skip to 11,111 and range to 11,172. The individual file therefore has 11,303 total sequence id numbers representing 11,303 individuals, of which some are offenders and some are nonoffenders. The sequence id number in the individual file links to the sequence id number in the offense file, where only offenders are documented. There are 3,595 total offenders, but since some offenders have multiple offenses, the total number of offenses is 10,214.

Boys who were born in 1945 and lived in Philadelphia, Pennsylvania, from the ages of 10 to 18.
