Transit Region Counties
Transit Regions are aggregated from one or more Census County boundaries that contain the majority of the region's transit system. Using counties allows for more consistency when aggregating data with different geographical bases (e.g. TIGER 2000, TIGER 2009, TIGER 2010, etc.). Below are the Counties that make up each Transit Region.
