Ensuring adequate food for families and individuals is also a centerpiece of national food policy efforts. In the United States where most state minimum wages have not been updated to provide what some groups deem a "livable wage", food assistance programs help provide food resources to individuals and families through monthly assistance. This primarily takes the form of monthly benefits that are calculated based on family income, adjusted for certain deductible living expenses and household size, and can only be used for the purchase of foods. The program known for decades as "food stamps" was revamped and renamed Supplemental Nutrition Assistance Program (SNAP) in 2008 to acknowledge the change from paper food stamps to electronic benefit transfer or EBT cards. SNAP is a mandatory spending program; the government must designate funds for the program sufficient to cover benefits for all who meet the eligibility requirements. The farm bill also authorizes funding for SNAP and other nutrition assistance programs that form a social safety net, projected to be at $772 billion over the 10-year-period from 2013 to 2022. In 2020, the USDA also created a COVID-19 food assistance program.
