SNAP Benefit Changes: What the Evidence Says About Food Assistance Reform

The Supplemental Nutrition Assistance Program, the nation's primary food assistance program, has been a consistent focus of policy debate over its eligibility rules, benefit levels, work requirements, and administrative structure. As Congress and the executive branch consider changes to the program, the research evidence on SNAP's effects and the consequences of previous modifications provides important context for evaluating proposed reforms. SNAP currently reaches approximately 42 million Americans in a typical month, with higher enrollment during economic downturns and lower enrollment during periods of economic expansion. The program provides monthly benefits on electronic benefit cards that can be used to purchase most food items from participating retailers. Maximum benefit levels are set by the USDA based on the cost of a low-cost nutritious diet, and actual benefits are reduced based on household income. Research on SNAP benefit levels documents that current benefits, even following the 2021 increase to the Thrifty Food Plan, leave many households unable to afford adequate nutrition for the full month. Studies using benefit sufficiency measures find that many households experience a gap between SNAP benefits and their actual food costs, particularly in high-cost-of-living areas. End-of-month food insufficiency, sometimes called the SNAP benefit cycle, is documented in research showing that food bank use, school nutrition program utilization, and emergency room visits for hypoglycemia-related conditions increase toward the end of SNAP benefit cycles. Work requirement proposals for SNAP have been a recurring feature of policy debates. As discussed in the context of Medicaid work requirements, evidence from previous SNAP work requirement implementations finds that the primary effect is coverage loss rather than increased employment. The population subject to SNAP work requirements includes a significant share of individuals who are working or who face barriers to stable employment, and administrative reporting requirements create obstacles that cause eligible individuals to lose benefits. Recent congressional proposals have included changes to SNAP eligibility rules, work requirements for broader categories of adults, modifications to how benefits are calculated, and shifts in the share of program costs borne by states versus the federal government. Research on these proposals has been conducted by the USDA's Economic Research Service, the Congressional Budget Office, academic researchers, and advocacy organizations. The research generally finds that reducing benefits or tightening eligibility increases food insecurity in affected populations. Time limits for able-bodied adults without dependents are an existing feature of SNAP law that has been modified multiple times. The current structure allows these individuals to receive SNAP for only three months in any 36-month period unless they meet work or activity requirements or live in areas with high unemployment where the time limit is waived. Research on time limit effects documents coverage loss for affected populations, with limited evidence of employment increases. The categorical eligibility provision, which allows states to extend SNAP eligibility to households receiving certain other benefits, has been a target of proposals to restrict eligibility. Research finds that categorical eligibility primarily simplifies administration rather than providing benefits to ineligible households, since households accessing categorical eligibility typically have modest incomes and assets that would qualify them under standard SNAP rules. Agricultural commodity and trade interests intersect with SNAP policy in the context of the Farm Bill, the legislation that authorizes SNAP and agricultural programs together. Agricultural producers benefit from SNAP because the program supports consumer food purchasing that generates market demand for agricultural products. The historical linkage of nutrition and agricultural policy in the Farm Bill has been both a source of bipartisan support and a point of ongoing tension as the program's scope and priorities evolve. The research evidence on SNAP's effectiveness is among the strongest in social policy: the program reliably reduces food insecurity, improves health outcomes, supports economic activity in low-income communities, and produces measurable benefits for child development. Policy modifications that reduce benefits or eligibility reverse these documented benefits for affected populations.
