The 7-county Minneapolis-Saint Paul region is expecting a shortage of construction workers by 2020. With the region’s constricted labor pool, the shortage will approach 600. However, if economic growth of the industry is able to continue at historic levels with a growing labor pool, the shortage could reach 2,750 workers. Construction occupations are highly unionized, making a complex labor ecosystem. Approximately 13.3% of the 7-county metro area is a member of a union, compared to 10.7% of the nation overall. In some zip codes, union membership is as high as 27% (55450, 55424), 28% (55372), or 31% (55417).
