The political polarization of metropolitan areas is occurring widely within the United States. By highlighting the political polarization that has been underway for decades in the Milwaukee, Wisconsin metropolitan area, this can serve as a way to understand political polarization within the St Louis metropolitan area. This article uses political and demographic data from the Missouri Information Spatial Data Information Service to take a close look at developments in the St Louis metropolitan area. Geographic Information System (GIS) was used and the maps were created using Archmap. The results suggest that political polarization is occurring within the St Louis metropolitan area.
