All of the studies use some source of administrative data, at least information on welfare benefit recipiency (table A2). Some studies had access to rich databases of linked administrative data that included a wide variety of program participation much beyond welfare receipt. Given the scope of resources available, unless areas had on-going efforts to create and maintain multi-link/multi-program databases, reporting was more limited. The resources in time and money to link data accurately can be very high. In addition to program participation, most studies (with the exception of District of Columbia) used unemployment insurance administrative data to get information on employment and earnings.

Other than TANF, food stamps, Medicaid, and employment data, several studies reported additional information from administrative data sources. These include use of child care subsidies, receipt of child support payments, child welfare reports of abuse and neglect, and use of emergency assistance. The specific studies that have these additional data and report on it in their study are listed in the table.
The length of follow-up for any of these sources of administrative data varied greatly. Some studies reported as much as two years of follow-up data for certain cohorts. The majority reported one year of data. Illinois had a combined rolling cohort, including as much information for each of the six cohorts that they had up to the date of analysis.
