What were relative resources of the north and south in the U.S. Civil war?

During the U.S. Civil War, the North possessed a significant advantage in resources, including a larger population of about 22 million compared to the South's 9 million, of which nearly 4 million were enslaved individuals. The North also had greater industrial capacity, producing 97% of the country's firearms and 96% of its railroad locomotives, which facilitated troop movement and supply lines. In contrast, the South relied heavily on agriculture, particularly cotton, and had fewer factories and railroads, leading to logistical challenges and resource shortages throughout the war. This disparity in resources played a crucial role in the North's eventual victory.
