The Supplemental Nutrition Assistance Program (SNAP) is the nation’s largest nutrition assistance program, helping 40 million low-income families put food on the table each month. As part of the 2018 Farm Bill reauthorization, proposed legislation before the House of Representatives would expand and intensify work requirements and remove benefits for 12 months or longer for those who do not comply with the requirements or obtain an exemption. Although adults caring for children younger than 6 would be exempt, adults caring for children ages 6 to 17 would be required to work or participate in employment and training activities at least 20 hours a week. This fact sheet summarizes data on households with children potentially affected by work requirements proposed in the House Farm Bill and key points about the role SNAP has played in reducing food insecurity among children and improving their long-term outcomes, as well as the short- and long-term health consequences for children who experience food insecurity.
