Master Sample Series

This codebook describes the contents of a data file from the Health Insurance Experiment, a large social experiment conducted by the RAND Corporation from 1974 to 1982 under a grant from the U.S. Department of Health and Human Services. The codebook provides data for 9142 persons, while enrolled in the experiment, regarding their eligibility to participate in the experiment and their family composition. The eligibility-family changes file consists of variables derived from administrative data maintained at RAND to keep track of participants over the course of the experiment. For each variable in the file, this codebook lists the data sources, defines all response codes, and tabulates the response frequencies.
