Definitions: Percent of total eligible population who participated in the Supplemental Nutrition Assistance Program (SNAP).
Persons are eligible for participation in SNAP (formerly the Food Stamp Program) if they meet certain resource and income tests. Not everyone who is eligible for food stamps elects to take them. More detailed information about eligibility is here: http://www.fns.usda.gov/snap/applicant_recipients/eligibility.htm#employment. SNAP eligibility rules were applied to the Current Population Survey (CPS) to estimate the total eligible population in each state.

USDA releases annual reports that include the percent eligible population who participated in SNAP, along with confidence intervals. These reports can be found by searching “Trends in Supplemental Nutrition Assistance Program Participation Rates” at http://www.fns.usda.gov/snap/. Annual data on the number of participants can be found at http://www.fns.usda.gov/pd/snapmain.htm.

Note: Maps use the natural break classification method, which reflects patterns
in the data by dividing the map into naturally occurring groups. Using statistical tools, this method
determines cut-off points for each group by identifying large gaps in data values.
Note: The District of Columbia, Puerto Rico and the U.S. Virgin Islands are
not included in maps and rankings because they are not states and therefore comparisons on many
indicators of child well being are not meaningful.
