The area is stable, with modest growth entirely within Kalamazoo County and minor declines in surrounding counties.

The Kalamazoo-Battle Creek-Portage CSA experienced modest growth, 1.4% to 1.8%, depending on how you define it:

4-County Region (Kalamazoo, Calhoun, St. Joseph, & Branch - I think this is the more technically correct definition):

CSA - 2010: 493,020
CSA - 2020: 501,781
Numerical Change: 8,761
Percent Change: 1.8%

Adding a fifth county - Van Buren (which, personally, I think makes sense to include, since Van Buren County is part of the Kalamazoo-Portage MSA):

CSA - 2010: 569,278
CSA - 2020: 577,368
Numerical Change: 8,090
Percent Change: 1.4%

Kalamazoo County as a whole had modest growth. It fell a bit short of its 2019 estimate, but still grew at a better rate than the State overall. The 3-4 other counties in the MSA all shrank, but barely (a range of -0.6% (St. Joseph) to -1.3% (Calhoun):

Kalamazoo County - 2010: 250,331
Kalamazoo County - 2020: 261,670
Numerical Change: 11,339
Percent Change: 4.5%

Somewhat surprisingly, Kalamazoo (city) lost a few hundred people, and Battle Creek (city) gained a few hundred. Portage had the most positive growth of the three primary urban zones in the CSA, at 5.6%. If Portage keeps increasing, it could soon overtake Battle Creek as second-largest city in the CSA:

Kalamazoo City - 2010: 74,262
Kalamazoo City - 2020: 73,598
Numerical Change: (664)
Percent Change: -0.9%

Battle Creek City - 2010: 52,347
Battle Creek City - 2020: 52,721
Numerical Change: 374
Percent Change: 0.7%

Portage City - 2010: 46,292
Portage City - 2020: 48,891
Numerical Change: 2,599
Percent Change: 5.6%

I think that the loss in population is because of Covid19 and the lack of many on campus students in 2020. East Lansing, Mt Pleasant, MI, Bloomington, IN, Athens, OH, ect... all lost population. This in spite that the 2019 population est. had shone a growth in population in all of those collage towns. Even Ann Arbor lost population compared to the 2019 est. In short, Covid19 made the 2020 census in accurate for most college cities as they lost their dorm population for that year.
