NCHS Data Linkage

NCHS Data Linked to SSA Social Security Benefit History Files

NCHS has linked various surveys with the Old Age, Survivors and Disability Insurance (OASDI) and Supplemental Security Income (SSI) benefit records collected from the Social Security Administration (SSA). Linkage of the NCHS survey participants with the SSA-OASDI and SSA-SSI data provides the opportunity to further study the elderly and disabled U.S. population.

The NCHS health surveys listed below were linked to five SSA Administrative Data Files: the Master Beneficiary Record (MBR) file, the Supplemental Security Record file (SSR), the Payment History Update System (PHUS) file, the 831 Disability Master File (831) and a special extract of summarized quarters of coverage (QOC) from the Master Earnings File.
