Indicators of Welfare Dependence: Annual Report to Congress, 2009-2013. Data Sources

04/01/2013

The primary data sources for this report are the Current Population Survey (CPS), the Survey of Income and Program Participation (SIPP), the Panel Study of Income Dynamics (PSID), and administrative data for the AFDC/TANF, FSP/SNAP, and SSI programs. Beginning with the 2001 report, there was a shift to using CPS rather than SIPP data for several indicators and predictors of welfare recipiency and dependence. This change was necessary because CPS data are updated annually, while SIPP updates
are available less frequently. The current report includes updated estimates for most of the SIPP-based indicators and risk factors based on newly available data from the 2004 SIPP panel.
 
For measures of receipt, dependency and poverty at a single point in time, the report primarily uses the Annual Social and Economic Supplement to the CPS, which measures income and poverty over an annual accounting period. As stated above, the CPS data are generally available on a more timely basis than the SIPP, and have been widely used to measure trends since the welfare reform legislation of 1996. However, because the CPS does not collect income information in the same detail as the SIPP, it has been subject to criticism for underreporting of income, particularly welfare income. To address this concern, some of the indicators in this report are based on CPS data that have been analyzed by the Transfer Income Model (TRIM3), a microsimulation model developed by the Urban Institute under contract to the Office of the Assistant Secretary for Planning and Evaluation. Although its primary purpose is to simulate program eligibility and the impact of policy proposals, the TRIM3 model also has been used to correct for underreporting of welfare receipt and benefits. Welfare caseloads in TRIM3 are based on CPS data, adjusted upward to ensure that total estimates of recipients equal the total counts from administrative data. To maintain consistency in data trends, we present estimates based on CPS data analyzed by TRIM3 beginning in 1993, the first year the TRIM3 microsimulation model became available.
 
As shown in Figure SUM 3, the overall measures of dependence and recipiency have not been greatly affected by the change in data sources. Both data sources show a decline in dependence between 1996 and 1999 and increases in dependence during the 2000s. Still, readers are cautioned against comparing measures for 1987-1995 from the SIPP data in the first three annual reports with the measures for 1993-2009 from the TRIM3-adjusted CPS data.
 
The Panel Study of Income Dynamics (PSID) is another source of data used in this report. Like the SIPP it provides longitudinal data, but over a much longer time period than the three- to four-year time period of the SIPP. With annual data on program receipt since 1968, the PSID provides vital data for measuring longer-term welfare use over periods of many years. Because the PSID indicators cover time spans over decades, they are updated less frequently than the CPS-based and SIPP-based measures.
 
Figure SUM 3. Recipiency and Dependency Rates from Two Data Sources: 1987 – 2009
Note: Recipiency is defined as receipt of any amount of AFDC/TANF, SSI or SNAP during the year. Dependency is defined as having more than 50 percent of annual family income from AFDC/TANF, SSI and/or SNAP. Dependency rates would be lower if adjusted to exclude welfare assistance associated with working. While only affecting a small number of cases, General Assistance income is included within AFDC/TANF income and veterans pension benefits are included in means-tested assistance income for SIPP-based receipt and dependency estimates prior to 2001.
 
Source: Unpublished tabulations from the Current Population Survey, Annual Social and Economic Supplement, 1994-2007, analyzed using the TRIM3 microsimulation model, and unpublished tabulations from the Survey of Income and Program Participation, 1987, 1990, 1992, 1993, 1996, 2001, and 2004, panels.
 
The report also draws upon administrative data for the AFDC/TANF, FSP/SNAP, and SSI programs. These data are largely reported in Appendix A. Like the CPS data, administrative data are generally available with minimal time lags. For this report, data through 2009 are used. To the extent possible, TANF administrative data are reported in a consistent manner with data from the earlier AFDC program, as noted in the footnotes to the tables in Appendix A. The fact remains that assistance under locally designed TANF programs encompasses a diverse set of cash and non-cash benefits designed to support families in making a transition to work, and so direct comparisons between AFDC receipt and TANF receipt should be made with caution. This issue also affects reported data on AFDC and TANF receipt in national data sets such as the CPS and SIPP.
