NCHS Survey Data Linked to the Department of Housing and Urban Development (HUD) Housing Assistance Program Files

Description

NCHS has linked 1999-2018 National Health Interview Survey (NHIS) and 1999-2018 National Health and Nutrition Examination Survey (NHANES) to administrative data through 2019 for the Department of Housing and Urban Development’s (HUD) largest housing assistance programs: the Housing Choice Voucher program, public housing, and privately owned, subsidized multifamily housing. Linkage of NCHS survey participants with HUD administrative records provides the opportunity to examine 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.
