The Chicago Council on Global Affairs reports that metro areas in the Midwest are aging and are growing much more slowly than the nation as a whole. Midwest metro population rose by only 7% from 2000 to 2015 compared to 14% for the nation.
In the 2000-2015 period immigrant populations in the Midwest rose by 34.5% growth and accounted for 37% of all mid-western metro growth in the last 15 years.
Immigration is responsible for majority of majority of population growth in five metro areas including metro areas of Chicago, Rockford, and Akron. In numerous other metro areas such as Cincinnati, Milwaukee and Minneapolis immigration accounts for at least a quarter of population growth.
Natives in the 35 to 44 age category are in striking decline. The number of native-born age 35 to 44 fell by 1.4 million persons or 24% between 2000 and 2015. An increase of 313,000 immigrants ages 35 to 44 years during the same period helped to offset the extreme native population loss in that category.
