In 1820 what states contain a major production area for cotton?

In 1820, the major production areas for cotton were primarily found in the Southern United States, particularly in states such as Alabama, Mississippi, Louisiana, Georgia, and South Carolina. The invention of the cotton gin in 1793 significantly boosted cotton production, making these states key players in the cotton economy. The climate and soil conditions in these regions were highly favorable for cotton cultivation, leading to their prominence in the industry during that time.
