Supplemental Security Income

Through the Supplemental Security Income (SSI) program, the federal government and the states provide cash assistance to people who are disabled, aged, or both and who have low income and few assets. CBO projects SSI spending under current law, prepares cost estimates for legislative proposals affecting SSI, and analyzes options for changing the program.
