title: IPUMS Contextual Determinants of Health (CDOH) Race and Ethnicity Measure: Residential Segregation - Index of Dissimilarity Inequity by County, United States, 2005-2022
title: Version 1

description: The IPUMS Contextual Determinants of Health (CDOH) data series includes measures of disparities, policies, and counts, by state or county, for historically marginalized populations in the United States including Black, Asian, Hispanic/Latina/o/e/x, and LGBTQ+ persons, and women.
The IPUMS CDOH data are made available through ICPSR/DSDR for merging with the National Couples' Health and Time Study (NCHAT), United States, 2020-2021 (ICPSR 38417) by approved restricted data researchers. All other researchers can access the IPUMS CDOH data via the IPUMS CDOH website.
Unlike other IPUMS products, the CDOH data are organized into multiple categories related to Race and Ethnicity, Sexual and Gender Minority, Gender, and Politics. The CDOH measures were created from a wide variety of data sources (e.g., IPUMS NHGIS, the Census Bureau, the Bureau of Labor Statistics, the Movement Advancement Project, and Myers Abortion Facility Database). Measures are currently available for states or counties from approximately 2000 to 2020.
The Race and Ethnicity measures in this release are indicators of residential segregation, which measures the physical separation of population groups into different areas (i.e., neighborhoods) in a geographic unit (i.e., a county or city). The index of dissimilarity is a measure of evenness and measures the proportion of a group's population that must move so that each sub-county geographic unit in a county has the same proportion of that group as the county. Census tracts are used as the sub-county geographic unit because census tracts nest within counties.
description: The purpose of this study is to provide researchers the ability to merge the NCHAT (National Couples' Health and Time Study) data with the Contextual Determinants of Health (CDOH).

description: The dataset provides measures of residential segregation as indices of dissimilarity for United States counties for the following racial-ethnic groups: White alone--Black alone, White alone--Asian alone, and White alone, not Hispanic or Latino--Hispanic or Latino. Please refer to page 2 of the User Guide for the formula used to create these indices.

description: record abstractsThe dataset includes <strong>MATCH_ID</strong> for all respondents in NCHAT. This variable should be used to merge the IPUMS CDOH variables to NCHAT surveys within ICPSR's virtual data enclave (VDE).The dataset also includes the variable <strong>GEOID_RANDOM</strong>. This variable is included so investigators can control for the county within their analyses (e.g., whether respondents are living within the same county) without knowing the actual county of the NCHAT respondent. This was done to preserve participant confidentiality.
