    • Original 2005 Megapolitan Model Identifies Contiguous Metro and Micropolitan Areas that are Linked By Business Connectivity, Transportation, and Environment
    • New 2006 Model Works on a Modified Version on Census Methods that Track Commuting. It is Very Close to the Census’s Combined Statistical Area Criteria. The Model Supplements the 2005 Geography
  • 11. Virginia Tech’s 2006 Metropolitan Hierarchy Megalopolis and Great Lakes Crescent, Sun Corridor and SoCal Two megapolitan areas that are proximate and occupy common cultural and physical environments and maintain dense business linkages Megaplex Piedmont, Great Lakes Crescent Three or more metropolitan areas with anchor principal cities over 150 miles apart that form an urban web over a broad area that is laced with Interstates Megapolitan Arizona Sun Corridor (Phoenix/Tucson), SanSac (San Francisco/ Sacramento) Two or more metropolitan areas with anchor principal cities between 75 and 150 miles apart that form an extended linear urban area along an Interstate Macropolitan Dallas/Ft. Worth, Washington/ Baltimore Two or more metropolitan areas that share overlapping suburbs but the main principal cities do not touch Metroplex Pittsburgh, Boise Current definition of the Census Bureau Metropolitan Examples Description Types

    • The New Population Threshold to Qualify as a Megapolitan Area will Be 5 Million People by 2040.
