SSI, or Supplemental Security Income, is a government-funded program in the United States that provides financial assistance to low-income individuals who are elderly, blind, or disabled. This program aims to help those who are unable to work and have limited resources to meet their basic needs. SSI provides monthly cash payments to eligible individuals to help cover the cost of food, shelter, and other essential expenses. Unlike Social Security benefits, SSI is not based on prior work history and is available to those who have never worked or have not worked enough to qualify for Social Security benefits. SSI not only provides financial support, but also offers access to other benefits such as Medicaid and food stamps. It serves as a safety net for vulnerable individuals and helps to alleviate poverty and improve their quality of life.
