Details

This data set was obtained from "NSW Data Files" and is a subset of the data collected for the original National Supported Work Evaluation Study (see source below). A portion of the summary of the study is quoted below. This quote was obtained from the website of the "Interuniversity Consortium for Political and Social Research" (see source below).

"This study is an evaluation of the National Supported Work Demonstration project, a transitional, subsidized work experience program for four target groups of people with longstanding employment problems: ex-offenders, former drug addicts, women who were long-term recipients of welfare benefits, and school dropouts, many with criminal records. The program provided up to 12-18 months of employment to about 10,000 individuals at 15 locations across the country for four years. In ten of these sites – Atlanta, Chicago, Hartford, Jersey City, Newark, New York, Philadelphia, Oakland, San Francisco, and Wisconsin, 6,600 eligible applicants were randomly assigned either to experimental groups (offered a job in supported work) or to control groups, and an evaluation was conducted on the effects of the Supported Work Program. "
