The Supplemental Nutrition Assistance Program (SNAP) is the largest of USDA’s 15 food and nutrition assistance programs, providing monthly benefits for purchasing food to those who apply for the program and meet the income and other eligibility criteria.

In fiscal 2017, 42.1 million Americans were enrolled in the program during an average month. ERS’s SNAP Policy Database provides information on policies in the 50 States and the District of Columbia that may affect SNAP participation. For example, online applications allow individuals to complete and submit an application for SNAP benefits over the Internet. Applicants then undergo an interview at the SNAP office or over the phone to complete the application process.

Online applications first became available in January 2002 and were offered in 44 States by December 2016. Although not all SNAP applicants use the online option, a high percentage of the SNAP caseload resides in States where it is available. The 44 States that provided online applications accounted for 93 percent of the national SNAP caseload in 2016. The monthly State-level information contained in the database can facilitate research on factors that may have an effect on SNAP participation and the program’s impacts.
