Economy of the United States |
---|
The economic history of the United States spans the colonial era through the 21st century. The initial settlements depended on agriculture and hunting/trapping, later adding international trade, manufacturing, and finally, services, to the point where agriculture represented less than 2% of GDP. Until the end of the Civil War, slavery was a significant factor in the agricultural economy of the South. The US was the world's largest economy for decades, possibly surpassed in the 21st century.
The New York metro area dwarfs all other cities for economic output by a large margin.
