This project contains a subset of code and datasets to be included in ABCD Curated Release 5.0, as part of the residential history-derived linked external data. Each folder contains the source files and code needed to compile measures in that domain for the mainland United States. The output of the R code in these folders was then sent to the DAIRC of the ABCD Study at UCSD, where these estimates were then linked to family-reported addresses. The datasets were curated to provide new constructs that provided information about social, built, and/or natural environments. Most datasets were selected to cover 2016-2018, the baseline year of the ABCD Study. While there are many datasets that are linked to the ABCD Study, the datasets included here are the following (organized by domain): **Amenities and Services (NaNDA):** - Parks - Social Services - Religious and Civic Organizations - Performing Arts and Sports Recreation Orgs **Community Health Burden** - PLACES database (CDC) **Metereology and Exposures** - EJSCREEN **Neighborhood Composite Measures** - Minority Health Social Vulnerability Index **Neighborhood Social Factors** - Neighborhood Disadvantage Principal Components - Census Return Rates - Number of Jobs and Job Density (LODES) - Opportunity Zones and Investment Scores - Rent and Mortgage Statistics **Residential Segregation** - Dissimilarity Index - Exposure/Interaction Index - Multi-Group Entropy Index - Gi* Statistics - Index of Concentration at the Extremes (ICE) **Urbanicity** - Vehicular density
