Supplemental Security Income (or SSI) is a monthly stipen provided to aged (legally deemed to be 65 or older), blind, or disabled persons based on need, paid by the United States Government. The program is administered by the Social Security Administration. Payments are made from the US Treasury general funds, not the Social Security trust funds. The payments are generally paid on the 1st of the month, for the current month (as opposed to social security benefits which are paid for the prior month). The program was created in 1974 to replace various state-administered programs which served the same purpose, as a way to standardize in the level of benefits through the addition of Title XVI (Title 16) of the Social Security Act.
