NCHS Data Linkage Activities

NCHS has developed a record linkage program designed to maximize the scientific value of the Center’s population-based surveys. Linked data files enable researchers to examine the factors that influence disability, chronic disease, health care utilization, morbidity, and mortality.

NCHS is currently linking various NCHS surveys with administrative data from the following:

• National Death Index (NDI)
• Centers for Medicare and Medicaid Services (CMS)
  • Medicare
  • Medicaid/CHIP
• United States Renal Data System (USRDS)
• Social Security Administration (SSA)
• Department of Housing and Urban Development (HUD)
• Department of Veterans Affairs (VA)
