MiCDA’s Geographic Linkages Repository (GLR)

MiCDA is partnering with the Health and Retirement Study (HRS), Panel Study of Income Dynamics (PSID) and National Health and Aging Trends Study (NHATS) to make contextual files and related documentation available in the MiCDA Enclave to approved researchers upon request.

The Geographic Linkages Repository (GLR) will facilitate linkages at multiple levels of geography (e.g. state, county, tract, zip code) so that researchers can more fully investigate the impact of the environments in which people live and work on later life health, well-being and related inequities.

National Neighborhood Data Archive (NaNDA). NaNDA is a nationwide collection of data with measures of the demographic, economic, social, and physical environments, generally at the level of Zip Code Tabulation Areas (ZCTA) and Census Track. Measures cover socioeconomic and demographic data, urbanicity, broadband and internet access, establishments or organizations by type, health care services, crime, schools, parks, public transit stops, polluting sites, roadways, street connectivity, traffic volume, voter patterns. A Zip Code to ZCTA crosswalk is included. More detailed information can be found on the NaNDA webpage and at OpenICPSR.

The Contextual Data Resource (CDR) is a collection of datasets designed to facilitate research on the role of place in shaping health and well-being. CDR includes measures of health care resources, demographic and socioeconomic data, air quality, crime and the food environment. Measures are available at various levels of geography (e.g., census tract, county, metro area, state). More detailed information can be found on the CDR webpage.

The State Policy & Politics Database (SPPD) is a compilation of annual data on state policies and politics that are particularly relevant for population health. The SPPD includes several categories of policies, including labor and economic policies (e.g., minimum wage levels, right to work laws), social safety net policies (e.g., earned income tax credits, SNAP), behavior-related policies (e.g., tobacco taxes, opioid prescribing), as well as the political ideology of the states’ government and citizens. Most measures are available annually from 1980 to 2021.
