§ 101. The Programs Covered – Old-Age, Survivors, and Disability Insurance (OASDI) and Supplemental Security Income (SSI)


Although the Social Security Act of 1935 established a wide range of income support programs and many additional programs have since been added to the Social Security Act, the phrase "Social Security" is used throughout this reference work to refer more narrowly to the programs found in Title II of that act. These include old-age insurance (retirement) benefits, survivors' benefits, and disability benefits. The full collection is referred to as Old-Age, Survivors and Disability Insurance or OASDI.

This reference work and accompanying on-line resources also cover questions of entitlement and benefit amount under Title XVI, the Supplement Security Income program (SSI). As its name suggests, Supplemental Security Income can be viewed as a backstop for Social Security, providing benefits for individuals in the same population segments who have insufficient income, either because they do not qualify for Social Security (having not had enough past covered employment) or because their Social Security benefits are too low.

See generally SSA, Fact Sheet on Social Security.
