back to County Voting Patterns in US Presidential Elections, 1976-2000
This project required two main pieces of data: ArcView shapefiles for the counties of the contiguous United State at as many points in time as was relevant, and election returns by county for multiple presidential elections.
Historical United State County (HUSCO) Boundary files
(Earle, Carville, Changyong Cao, John Heppen, and Samuel Otterstrom. 1999. The Historical United States County Boundary Files 1790 - 1999 on CD-ROM. Geoscience Publications. Louisiana State University.)
(Source: UW Map Library) - "The Historical United States County Boundary Files (HUSCO) CD contains ArcView shapefile format county boundary files for the contiguous United States for each decade from 1790 through 1990 (also 1999). Files include county and state names as well as FIPS identification numbers and county area estimates. Territories enumerated by the U.S. Census are also included."
