Urban areas

Due to suburbanization, the typical urban area is polycentric rather than being centered around a large historic core city. Huntsville is unique in that it is split into two separate urban areas, one for most of the city and Madison, and the smaller one including the Big Cove valley area and part of northern Owens Crossroads.[5][6]
