Social Security Program Data
Annual Trustees Reports provide estimates describing the actuarial status of Social Security's Old-Age and Survivors Insurance (OASI) and Disability Insurance (DI) Trust Funds under current law. In making these estimates, the Trustees make key demographic assumptions and economic assumptions. The intermediate set of assumptions reflects the Trustees’ best estimates of future experience.
The following tables provide historical and projected populations of the Social Security area by single
year of age, sex, marital status, and year for the historical and projected periods. The
Social Security area is composed of: (1) residents of the 50 States and the District of Columbia (adjusted
for net census undercount); (2) civilian residents of Puerto Rico, the Virgin Islands, Guam, American
Samoa, and the Northern Mariana Islands; (3) Federal civilian employees and persons in the U.S. Armed
Forces abroad and their dependents; (4) non-citizens living abroad who are insured for Social Security
benefits; and (5) all other U.S. citizens abroad.
