Which American metropolitan areas are poised for large population gains in the coming years? One prediction says Dallas-Fort Worth will soon be the third largest metro area:

Dallas-Fort Worth is one of the country’s fastest growing metropolitan areas…

Business expansion and relocations are fueling the Dallas region’s growth, putting it on track to overtake the Chicago area and become the third-most-populous metro within the decade…

Dallas-Fort Worth is on track to be the only U.S. metropolitan area to house two cities with populations over 1 million in the next five years, as people and companies seek profit, opportunity and room to grow.

The population shift to the Sunbelt continues.

As for Chicago, it was passed by Toronto in population, Houston might pass it soon, and Dallas-Fort Worth pass the metropolitan area population. How far will the city and metropolitan area be down lists in a few decades?

Cities and metropolitan areas rise and fall in population over time. Chicago was once smaller than St. Louis than shot past it with the latter losing a lot of population in the 1900s. Where will the new boom cities be?
