Size and Scope of the Supplemental Security Income Program

• About 8.2 million people received federally administered payments in December 2017.
• The average monthly payment in December 2017 was $542.
• 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 27 percent were aged 65 or older.
• Most (86 percent) were eligible on the basis of blindness or a disability.
• Six out of 10 recipients under age 65 were diagnosed with a mental disorder.
• Fifty-seven percent of SSI recipients had no income other than their SSI payment.
• Thirty-three percent of SSI recipients also received Social Security benefits.
• Of the people receiving SSI benefits, 1.5 percent were residing in a Title XIX institution where Medicaid was paying more than half of the cost.
• Despite their disabilities, about 342,000 recipients (4.8 percent) were working in December 2017.

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;
• noncitizens;
• diagnoses of recipients under age 65;
• recipients who work;
• applications;
• awards;
• 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 Information Resources edited the report and prepared it for publication.
