One way to view the economy is to compare the imports and exports. Hickman County produces more revenue from two business categories, excepting government, than it spends on outside products:
- Crop and Animal Production. While agriculture is comparatively small, it remains important to the economy and to many families.
- Utilities. The headquarters of the Meriwether Lewis Electric Cooperative is in Centerville. Natural Gas is managed largely by the town of Centerille. Both Centerville and Dickson provide water and sewer service to county residents. Dickson Electric serves a significant portion of the East Hickman area.
