Centreville and Marion are the two largest urban areas and have economies based on small manufacturing and farming with Centreville also having a forest products industry and Marion two institutes of higher learning.

The Cahaba coal field is unique among North American coal basins because it contains the thickest succession of Lower Pennsylvanian strata on the continent and is the southernmost coal field of the Appalachian thrust belt. The Cahaba field is the oldest in Alabama with the first surface mine beginning operation in Bibb County in 1815, while the states first underground mine was established in Shelby County in 1856.
