New Beneficiary Data System (NBDS)
(released March 1997)

The NBDS, developed over the past decade, contains extensive information on the changing circumstances of aged and disabled beneficiaries. Based initially on a national cross-sectional survey of new beneficiaries in 1982, the original data base has been expanded with information from administrative records and a second round of interviews in 1991. Variables measured in the original New Beneficiary Survey include demographic characteristics; employment, marital, and childbearing histories; household composition; health; income and assets; program knowledge; and information about the spouses of married respondents. The NBDS contains unique measurements that make it valuable not only for studies about Social Security but also for studies of health, economic, labor, gerontological, and welfare issues.
