National Archive of Criminal Justice Data
This dataset is maintained and distributed by the National Archive of Criminal Justice Data (NACJD), the criminal justice archive within ICPSR. NACJD is primarily sponsored by three agencies within the U.S. Department of Justice: the Bureau of Justice Statistics, the National Institute of Justice, and the Office of Juvenile Justice and Delinquency Prevention.

The Transitional Aid Research Project (TARP) was a randomized field experiment conducted in Texas and Georgia in 1976-1977 that was designed to reduce recidivism among ex-prisoners by lowering incentives for re-engaging in property crime through provision of minimal levels of income support and extension of some unemployment insurance coverage to released prisoners. This study evolved out of an earlier LIFE (Living Insurance for Ex-Prisoners) study conducted in Baltimore, Maryland in the early 1970s. In the LIFE study, 500 prisoners with a high probability of re-arrest were randomly assigned at release from prison to experimental and control groups which varied by the amount of money received (contingent upon employment or unemployment and job placement services provided). The results showed that ex-prisoners receiving payments were less likely to be re-arrested for property theft-related crimes than those who received only job placement or no services or payments of any kind. The United States Department of Labor commissioned the TARP experiment, designed to replicate the LIFE experiment while providing a larger and more representative sample of prisoners, greater variation in treatment conditions, and administration of payments and job placement services through existing agencies rather than by a special purpose project staff. Texas and Georgia were the states chosen for the experiment, and stratified random samples of inmates were assigned, at the time of release from prison, to experimental and control groups. The groups varied in the amount of money and job placement services they received upon their release. Originally, the data were recorded in nine files for each state corresponding to each of the nine different sources of information for each TARP case. The ICPSR data collection combines these into one file for each state: Part 1 for Texas, and Part 2 for Georgia. Each file contains over 1,500 variables, clustered in nine topic areas for each inmate: (1) prison history (e.g., background information, psychological and aptitude test data, and prior criminal and present incarceration activity), (2-5) data from four personal interviews (conducted at the prerelease, three-month, six-month, and 12-month stages and that include living arrangements, employment history, and financial status), (6) state arrest data, (7) records of TARP payments received, (8) social security wages, and (9) parole records.
These data are freely available.

This survey was funded by:
- United States Department of Labor
Scope of Study
Subject Terms: crime control programs, employment services, ex-offender employment, ex-offenders, inmate release plans, job history, job placement, occupational mobility, parole services, parolees, postrelease programs, prison inmates, recidivism, recidivism prediction, social adjustment, social reintegration, unemployment insurance
Date of Collection:
Universe: All prisoners in Georgia and Texas eligible for parole who were not returning to unsampled rural counties, who were not returning to live outside of the state, and who did not have existing warrants or detainers against them.
Data Types: administrative records data, experimental data, survey data
Sample: Stratified random sampling was employed to obtain 2,007 prisoner participants in Georgia and 1,975 prisoner participants in Texas, who were then assigned to one of six experimental and control groups when released from prison. The experiment lasted one year beyond that date.

(1) prison records, (2) personal interviews, (3) state arrest records, (4) local and county police files, (5) Texas and Georgia Employment Security Office records, (6) Georgia and Texas Employment Services records, and (7) parole records
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.
