History of Supplemental Security Income in Timeline

By Popular Timelines Editorial Team · Updated: July 24, 2026

Supplemental Security Income (SSI) is a United States federal program funded by general tax revenues, not Social Security taxes. It is designed to provide monthly cash assistance to individuals with limited income and resources who are aged 65 or older, blind, or disabled, including children with disabilities. To qualify, applicants must meet strict financial requirements regarding countable income and assets, as well as non-financial criteria related to their age, disability status, or blindness. SSI is distinct from Social Security Disability Insurance (SSDI), as eligibility is based on financial need rather than prior work history. In many states, SSI recipients also automatically qualify for Medicaid to help cover healthcare expenses. The program serves as a vital safety net, aiming to meet the basic needs for food, clothing, and shelter for some of the most vulnerable members of society.
