Greater Minnesota’s Trade-Center Hierarchy
By Will Craig and Bruce Schwartau, University of Minnesota

Cities across Greater Minnesota provide the jobs, education, goods and services, homes, meeting places, and identity for nearly half of the state’s population.  They are the hubs of activity, connected by roads to each other, to the Twin Cities, and to the national economy.  Trade Center size and vitality are important considerations in planning for highway maintenance and upgrades.  City vitality changes over time, so it needs to monitored regularly.

Past efforts to measure economic activity have been based on complicated analyses of business data from Dun and Bradstreet.  Authors of that methodology suggested using a simpler approach based on sales tax information.  Our research took that approach, using sales tax data from the Minnesota Department of Revenue.  We compared past approaches to determining Trade Center levels with the sales tax approach and found very similar results.

We then used current sales tax data to rank and classify cities today.  Change is occurring.  Mankato has moved up the urban hierarchy and is now a primary regional center on par with St. Cloud, Rochester, and Duluth; together these four cities account for 28% of taxable retail and service sales in Greater Minnesota.  Cities with populations under 5,000 and Iron Range cities tend to be losing ground.  Cities in lake regions of the state are growing as they take advantage of seasonal sales.
