SocScape - racial diversity change maps

Racial diversity change dataset shows temporal changes in racial diversity/dominant race in a single map. Changed areas are shown in stripes with the color of narrower stripes indicating the earlier year (f.e 1990) and broader stripes indicating the later year (f.e. 2000). Unchanged areas are shown in original color assign to this class in racial diversity maps. Detailed description of racial diversity change dataset is here.


DATA AVAILABILITY:  351 urban areas within metropolitan areas for 1990-2000, 2000-2010 and 1990-2010 comparison. Change map is limited to 2010-urban areas of main city in MSA.

For more information please see also the SocScape user guide and SocScape tutorial: "Working with demographic grids in QGIS."  


For downoload change maps for metropolitan areas select name of MSA from the right menu and click "Downolad"




Data are organized as zip archive. Each zip archive contains a few directories with a data for selected metropolitan areas:

  • 3 directories with racial diversity change map in ESRI shapefile format for 1990-2000, 2000-2010 and 1990-2010.
  • legend_files - directory with symbology files for QGIS and ArcGIS.  
  • transition_matrix - directory with transition matrices for 1990-2000, 2000-2010 and 1990-2010.
