Date of Collection:
Unit of Observation:
Felony court filings during the month of May in even years from 1990-2006 and 2009 in the 75 most populous counties in the United States.
Data Collection Notes:
Part 1, 1990-2009 Cumulative Data, has its own
codebook, which is separate from the codebook for Part 10, 2006 Data. Parts 6, 7, and 8, 1998-2004 Data, also have their own codebooks. Parts 2-5, the 1990, 1992, 1994, and 1996 individual-year data files, share the same codebook.
Part 6, 1998 Data, contains over 100 new variables that were created by the principal investigator.
Parts 2-5, the 1990, 1992, 1994, and 1996 data
files, were created from the 1990-1996 Cumulative Data file.
This version of the data supersedes all previous National Pretrial Reporting Program files.
Variable names and value labels have been made consistent across the 1990, 1992, 1994, 1996, 1998, 2000, 2002, 2004, and 2006 files. All years use "8" codes for not applicable and "9"
codes for missing data. Since some variables did not exist for all years, there may be instances in which all cases are missing for a variable within a given year.
There are 25 additional variables in Part 10, 2006 Data that are not in Part 1, 1990-2009 Cumulative Data.
In a two-stage sampling process, the first stage was a
stratified sample to select 40 of the 75 most populous counties, and
the second stage was a systematic sample of defendants based on felony
filings within each selected county.

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:
Checked for undocumented or out-of-range codes.
