In 1981, to take advantage of recently relaxed state usury laws, Citibank relocated its primary credit card center from New York City to Sioux Falls. Some claim that this event was the primary impetus for the increased population and job growth rates that Sioux Falls has experienced over the past quarter-century. Others point out that Citibank's relocation was only part of a more general transformation of the city's economy from an industrially based one to an economy centered on health care, finance, and retail trade.
