This report documents the extent and severity of food insecurity among working-age veterans, ages 18–64, who made up 76 percent of the United States’ veteran population in 2019. Food insecurity occurs when individuals have limited or uncertain access to enough food because they lack economic resources. In 2015–19, 11.1 percent of working-age veterans lived in food-insecure households, and 5.3 percent lived in households with very low food security, the most severe range of food insecurity where households report reductions in food intake. Food insecurity varies among working-age veteran subpop-ulations defined by age, area of residence, disability status, educational attainment, gender, geographic region, household composition, income, labor force participation status, race and ethnicity, and military service history. The report compares food insecurity among working-age veterans and nonveterans to examine the association between military service and food insecurity. After adjusting for observable differences between working-age veterans and nonveterans, we find veterans are 7.4 percent more likely to live in a food-insecure household.
