description: The National Crime Surveys data are organized by collection quarter, and six quarters comprise an annual file. For example, for the 1979 file the four quarters of 1979 are included, as well as the first two quarters of 1980.
Parts 1-7 as well as Parts 17 and 19 are hierarchically structured, with four levels. The first level, the household ID, has a logical record length of 54 characters and contains 8 variables. The second level, the household, has a logical record length of 204 with 89 variables. The third, or person, level has a logical record length of 142 and 57 variables, and the final level, the incident level, has a logical record length of 481 with 327 variables. The case counts per level are as follows: household level: 178,324 to 217,814 per part, person level: 316,094 to 393,685 per part, incident level: 28,564 to 43,959 per part. The person-level files contain data on all victims with a maximum of four incidents each, and a 10-percent sample of non-victims. The unit of analysis is the victim.
The subset of rape cases includes attempts and completed rapes.
