Data supporting paper A. Dmowska and T. F. Stepinski (2019) Mapping changes in racial composition in the United States using US census tract historical data, (paper submitted to Historical Methods: A Journal of Quantitative and Interdisciplinary History)
- Historical census tracts showing racial composition and diversity/dominant race classification in US cities between 1910-2010 (available as ESRI Shapefiles). For the purpose of mapping racial composition for the period 1910-2010 we reclassified racial data from particular census years into maximum 5 categories to assure comparability between censuses. The final product is made available as a set of zip archives for each metropolitan area. Each zip archive contains ESRI shapefile for the available years and QGIS legend file to map racial diversity classification.
Data supporting paper A. Dmowska and T. F. Stepinski (2019) Racial Dot Maps Based on Dasymetrically Modeled Gridded Population Data, Soc. Sci. 8(5), 157
- Racial dot maps for each county in the conterminous U.S. Racial dot map are based on 2010 high resolution demographic grids. Data are organized as a zip archive for each state in the conterminous U.S. Each zip archive contain racial dot maps for counties in this state. Data can be downloaded from this webpage.
