Approximately 85% of both the North and South white populations lived on family farms, both regions were predominantly agricultural, and mid-century industry in both was mostly domestic. But the Southern economy was pre-capitalist in its overwhelming reliance on the agriculture of cash crops to produce wealth, while the great majority of farmers fed themselves and supplied a small local market. Southern cities and industries grew faster than ever before, but the thrust of the rest of the country's exponential growth elsewhere was toward urban industrial development along transportation systems of canals and railroads. The South was following the dominant currents of the American economic mainstream, but at a "great distance" as it lagged in the all-weather modes of transportation that brought cheaper, speedier freight shipment and forged new, expanding inter-regional markets.
