The Transitional Aid Research Project (TARP) was an experiment conducted in Texas and Georgia. 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. These files included each inmate's prison history, data from four interviews, state arrest data, record of TARP payments, social security wages and parole records. The ICPSR dataset has combined these into one file for each state.
