A primary purpose of this study is building a knowledge base for monitoring the competitive position of the Twin Cities metropolitan area and measuring the value of the Minneapolis-St. Paul International Airport to its community. The creation of value is driven by the exports of goods and services to market destinations outside the Minneapolis-St. Paul metropolitan area. The knowledge base is intended to allow users of this report to: measure the value of the Minneapolis-St. Paul International Airport in terms of demand for air transportation, monitor the competitive position of the Minneapolis-St. Paul area; and market the Minneapolis-St. Paul International Airport.Minnesota Department of Transportatio
