Because of ethical and legal considerations, FNS cannot examine the effect of participation in SNAP on outcomes such as food security through experimental studies that would require withholding benefits from those eligible. Therefore, this study was conducted to identify whether regression modeling of extant data could yield adequate comparison groups to assess SNAP outcomes.

This report – the latest in an annual series – presents estimates of the percentage of eligible persons, by state, who participated in SNAP during an average month in FY 2007 and in the two previous fiscal years. This report also presents estimates of state participation rates for eligible “working poor” individuals (persons in households with earnings) over the same period. 

WIC provides food, nutrition education, breastfeeding support, and health care and social service referrals to nutritionally at-risk low-income pregnant women, new mothers, infants, and children through age 4. This report offers updated estimates of the population that met these criteria and was eligible for WIC benefits in each of the years 1994 through 2007.

This report is the latest in a series on SNAP participation rates. Estimates are based on the March 2008 Current Population Survey and program administrative data for FY 2007. 

The Food Stamp Program (FSP) helps needy families purchase food so that they can maintain a nutritious diet. Families are eligible for the program if their financial resources fall below certain income and asset thresholds. However, not all eligible families participate in the program. Some choose not to, while others do not know they are eligible. The participation rate—the ratio of the number of participants to the number of eligibles—reveals the degree to which eligible families participate.

The number of people receiving food stamps fell by over 5.9 million between summer 1994 and summer 1997, with most of the decline occurring in the year between September 1996 and September 1997. This decline occurred during a period of strong economic growth – unemployment fell, inflation stayed low, and the percentage of Americans living in poverty fell slightly. In the same period, Congress enacted and states implemented sweeping reforms to the Food Stamp Program and to the nation’s welfare programs.

This report reviews recent approaches to estimating the numbers of persons eligible for and participating in WIC. It also describes issues concerning these estimates that may be worthy of review and synthesizes research on these issues.

This pamphlet provides estimates for Food Stamp Program participation rates by states. It will be the first widely-released document showing the percentage of eligible people, by state, who actually participate in the program. Because the data are from January 1994, prior to the enactment of the Personal Responsibility and Work Opportunity Reconciliation Act of 1996, they provide baseline data on participation rates prior to the enactment of welfare reform.

This report provides a comprehensive picture of individuals’ patterns of participation in the Food Stamp Program during the early 1990s, a period of rapid caseload growth. Based on data from the 1990 and 1991 SIPP panels (national longitudinal surveys covering the period from late 1989 to early 1994), the research addresses questions about why individuals enter and leave the FSP, how long participants stay on the program, whether individuals return at a later time and what factors distinguish those who are more dependent on the program from those who are less dependent.
