This report presents interim findings as to the impact of the Welfare to Work Voucher Program on the quality of a family’s residential location, on employment and earnings, and on receipt of public assistance. The analysis, based on a six-site research sample of 8,732 families, makes use of outcome measures derived from tract-level Census data and person-level administrative data. The impact estimates in this report encompass a follow-up period that is five quarters in duration for all sites, and longer for some sites, reflecting the timing of random assignment and the availability of outcome measures.
