Food Stamp Program - Overview

The Food Stamp Program, administered by the U.S. Department of Agriculture's (USDA) Food and Nutrition Service, is the largest food assistance program in the country, reaching more poor individuals over the course of a year than any other public assistance program. Unlike many other public assistance programs, the Food Stamp Program has few categorical requirements for eligibility, such as the presence of children, elderly, or disabled individuals in a household. As a result, the program offers assistance to a large and diverse population of needy persons, many of whom are not eligible for other forms of assistance.

The Food Stamp Program was designed primarily to increase the food purchasing power of eligible low-income households to the point where they can buy a nutritionally adequate low-cost diet. Participating households are expected to be able to devote 30 percent of their counted monthly cash income (after adjusting for various deductions) to food purchases. Food stamp benefits then make up the difference between the household's expected contribution to its food costs and an amount judged to be sufficient to buy an adequate low-cost diet. This amount, the maximum food stamp benefit level, is derived from USDA's lowest-cost food plan, the Thrifty Food Plan (TFP).

The Federal government is responsible for virtually all of the rules that govern the program, and, with limited variations, these rules are nationally uniform, as are the benefit levels. Nonetheless, States, the District of Columbia, Guam, and the Virgin Islands, through their local welfare offices, have primary responsibility for the day-to-day administration of the program. They determine eligibility, calculate benefits, and issue food stamp allotments. The Food Stamp Act provides 100 percent federal funding of food stamp benefits. States and other jurisdictions have responsibility for about half the cost of state and local food stamp agency administration.

In addition to the regular Food Stamp Program, the Food Stamp Act authorizes alternative programs in Puerto Rico, the Northern Mariana Islands, and American Samoa. The largest of these, the Nutrition Assistance Program in Puerto Rico, had an average of 1.1 million participants in 2001, funded under a federal block grant of $1.3 billion. Unless noted otherwise, the food stamp caseload and expenditure data in this Appendix include costs for the Nutrition Assistance Program in Puerto Rico. Prior to 1982, the regular Food Stamp Program operated in Puerto Rico, under modified eligibility and benefit rules.

The Food Stamp Program has financial, employment/training-related, and "categorical" tests for eligibility. The basic food stamp beneficiary unit is the "household." Generally, individuals living together constitute a single food stamp household if they customarily purchase food and prepare meals together. Members of the same household must apply together, and their income, expenses, and assets normally are aggregated in determining food stamp eligibility and benefits. Except for households composed entirely of TANF, SSI, or general assistance recipients (who generally are automatically eligible for food stamps), monthly cash income is the primary food stamp eligibility determinant. Unless exempt, adult applicants for food stamps must register for work, typically with the welfare agency or a state employment service office. To maintain eligibility, they must accept a suitable job if offered one and fulfill any work, job search, or training requirements established by the administering welfare agencies.

Food stamp benefits are a function of a household's size, its net monthly income, its assets, and maximum monthly benefit levels. Allotments are not taxable and food stamp purchases may not be charged sales taxes. Receipt of food stamps does not affect eligibility for or benefits provided by other welfare programs, although some programs use food stamp participation as a "trigger" for eligibility and others take into account the general availability of food stamps in deciding what level of benefits to provide.
