Sioux Falls, seat of South Dakota's Minnehaha County, is the largest city in the state and the center of the metropolitan statistical area that includes Sioux Falls as well as Lincoln and Minnehaha counties. The city first grew during the Dakota boom years of the late nineteenth century as the arrival of the railroad made possible the nationwide transportation of granite quarried in Sioux Falls. Sioux Falls has grown in many ways since then, and consistently tops the rankings by Forbes and Inc. magazines of top cities for business.
