NCHS Data Linked to Social Security Benefit History Data

NCHS has developed a record linkage program designed to maximize the scientific value of the Center's population-based surveys. NCHS is currently linking various NCHS 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.

 

Overview of NCHS-SSA Linkage

The NCHS health surveys 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. A quick overview of the files can be found in the Description of the Linkage and a more detailed description of these files and the variables contained in each file can be found in the NCHS-SSA data codebook.
