In 2003, the Child Support Directors Association of California contracted with the Urban Institute to develop a cost avoidance estimate for California using the same methodology used for the Office of Child Support Enforcement study. The results of that study are presented here (for state fiscal year 2000-01) and cover the following programs: the California Work Opportunity and Responsibility to Kids program, the Food Stamp Program, Medi-Cal, the Supplemental Security Income program, and federal housing assistance.
