Size and Scope of the Supplemental Security Income Program
- About 8.1 million people received federally administered payments in December 2018.
- The average monthly payment in December 2018 was $551.
- Total payments for the year were almost $55 billion, including almost $3 billion in federally administered state supplementation.
Profile of Recipients
- The majority were female (53 percent).
- Fourteen percent were under age 18, 58 percent were aged 18 to 64, and 28 percent were aged 65 or older.

Since 1974, the Supplemental Security Income (SSI) program has guaranteed a minimum level of income for needy aged, blind, or disabled individuals. Each year, we issue a report that presents data on the SSI program and the people who receive benefits from it. The report covers such topics as:
- federal benefit rates, total annual payments, and total recipients;
- federally administered payments;
- recipients of Social Security, SSI, or both;
- children under age 18;
- diagnoses of recipients under age 65;
- recipients who work;
- outcomes of applications for disability benefits; and
- suspensions, terminations, and duration of eligibility.
Tables from the discontinued reports Children Receiving SSI and SSI Disabled Recipients Who Work were incorporated into this report beginning with the 2007 edition.
Aneer Rukh-Kamaa managed the preparation of this report and prepared the statistical tables and narratives. Staff of the Office of Dissemination edited the report and prepared it for publication.
