National Hospital Care Survey (NHCS) linked to Department of Housing and Urban Development (HUD) Administrative Housing Data

Description

Through its data linkage program, NCHS has been able to expand the analytic utility of the data collected from the 2014 and 2016 National Hospital Care Surveys (NHCS) by linking patient records with up to three years of administrative housing data from the U.S. Department of Housing and Urban Development’s (HUD) largest housing assistance programs: the Housing Choice Voucher (HCV) program, Public Housing (PH) , and privately owned, subsidized Multifamily housing (MF). These innovative linked data will support a wide array of patient outcomes studies, including the opportunity to study complex relationships between housing and health.

Summary of Differences

The restricted-use file may include lower-level geography and select variables not available on the public-use file due to possible disclosure risk. Most restricted-use geographic NCHS variables can only be used to merge external data or to categorize geographic areas with similar characteristics. Researchers should not estimate regions smaller than the specific survey's sample design would support, even when smaller levels of geography are available.
