Once primarily a producer of raw materials, Minnesota's economy has transformed to emphasize finished products and services. Perhaps the most significant characteristic of the economy is its diversity; the relative outputs of its business sectors closely match the United States as a whole. Minnesota's economy had a gross domestic product of $383billion in 2019, with 33 of the United States' top 1,000 publicly traded companies by revenue headquartered in Minnesota, including Target, UnitedHealth Group, 3M, General Mills, U.S. Bancorp, Ameriprise, Hormel, Land O' Lakes, SuperValu, Best Buy, and Valspar. Private companies based in Minnesota include Cargill, the largest privately owned company in the United States, and Carlson Companies, the parent company of Radisson Hotels.
