Unit of Observation:
All persons in the United States aged 12 and older.
Data Collection Notes:
The 2012 Collection Year Incident-Level Extract File was created from the record-type files and includes information on victims of crime; nonvictims are not included. Under the collection year format a crime incident is included based on when the interview is conducted, not on when the crime incident occurred.
The data were collected by the United States Department of Commerce, Bureau of the Census.
The 2012 data contain replicate weights for household, person, incident, and victimization to facilitate standard error computations given the sampling design of NCVS.
The 2012 data have a change in how the victimization totals are computed. Series crimes are now included with up to 10 occurrences.
Stratified multistage cluster sample.
The data files include several weight variables used to calculate national estimates of: households, persons, victimizations, and incidents. The codebook describes how to use the weights.
Mode of Data Collection:
computer-assisted personal interview (CAPI),

these procedures, ICPSR performed the following processing steps for this data collection:
Performed consistency checks.
Created variable labels and/or value labels.
Standardized missing values.
Performed recodes and/or calculated derived variables.
