Fig. 2.   The following periods represent changes in public policies and the enrollment of Wisconsin children is compared for: Period 1, which indicates Aid to Families with Dependent Children; Period 2, which indicates a welfare reform pilot period known as Pay for Performance; and Period 3, which indicates the initiation of Temporary Assistance to Needy Families or Wisconsin Works. Monthly and quarterly enrollment data of children under the age of 18 were analyzed using linear regression analysis for Medicaid/AFDC, Medicaid/Healthy Start, Food Stamps, AFDC/W-2, and WIC. Slopes of lines for each safety net program indicate the average increase or decline in enrollment per month during each consecutive period.
