Data Collection Notes:
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.

Stratified multistage cluster sample.
Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, ICPSR performed the following processing steps for this data collection:
Performed consistency checks.
Performed recodes and/or calculated derived variables.
Checked for undocumented or out-of-range codes.
