How much factories did the north have during the civil war?

During the Civil War, the Northern states had approximately 110,000 factories, which produced a significant majority of the nation's industrial output. This industrial advantage included the production of weapons, ammunition, and other war materials, allowing the Union to sustain its military efforts effectively. In contrast, the South had far fewer factories, around 20,000, which limited its capacity to equip and supply its troops. This disparity in industrial resources played a crucial role in the outcome of the war.
