The estimates also show that most of the population growth was in the state's suburban areas. Five of the fastest growing cities are within 30 miles of Birmingham. The second fastest growing city was Millbrook in Elmore County near Montgomery...that was followed by the Huntsville suburb of Madison and the Birmingham suburbs of Pelham and Helena.
