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 has released its first fully-synthetic linked data file and created a verification process so that researchers can confirm synthetic data results against the original data.
