NCHS Data Linkage Program

The NCHS Data Linkage Program is designed to maximize the scientific value of the Center\u2019s population-based surveys by linking data from health surveys with data from vital and administrative records. Linked data files enable researchers to examine factors that influence disability, chronic disease, health care utilization, and mortality. Linked data files also maximize scientific value by creating an efficient means to expand the analytic potential of both the survey and administrative data, so enabling analyses that would not be possible with either data source alone.CS306776factsheet-datalinkage-508.pdf2019667
