About:

Historic census data were collected from the University of Virgina's Geospatial and Statistical Data Center and processed in ArcGIS to generate historic time period overlays. Special thanks to ESRI's George Dailey and Ray Carnes for providing map images for top animation (choropleth) and to SAL interns Abby Mannelin (data processing) and Cassie Stearns (data processing and Flash animation) for help generating second animation (dot density).

These data can be available for GIS analysis. Please contact Jon Caris with questions or to access these data.
