Alabama statistical areas

The U.S. currently has 35 statistical areas that have been delineated by the Office of Management and Budget.
On July 21, 2023, the OMB delineated nine combined statistical areas, 13 metropolitan statistical areas, and 13 micropolitan statistical areas in Alabama. As of 2023, the largest of these is the Birmingham-Cullman-Talladega, AL CSA, encompassing the area around the state's second largest city, Birmingham.

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.
