Only a few notable changes in Michigan:

1. The Detroit CSA seems to have picked back up Lenawee County (pop. 99,892 in 2010) after having lost the county in 2000, which brings it back up to 5,318,744 at the 2010 Census, a small gain from the previous iteration of the CSA at 5,218,852. I believe that Lenawee barely missed the cut in 2010. Macomb, Oakland and Wayne remain the only three core counties.

2. The biggest change is that the Grand Rapids MSA has finally been realigned to reflect more of its urban area growth. It loses rural Newaygo (pop. 48,460) to the north and Ionia (63,905) to the east, but picks up more urban Ottawa County (263,801) and rural Montcalm (63,342) to the immediate northeast. I'm not sure, but the redefined metro may actually have a net loss in land area, but the population for the 2010 Census increases to 988,938 from 774,160.

The CSA is redefined with a population of 1,379,237 from 1,321,557. Allegan and Muskegon counties and the redefined Grand Rapids MSA are joined by two micropolitan areas: rural Ionia (just kicked out of the MSA) and rural Mecosta to the northeast, the only new county in this entire equation.

3. Battle Creek MSA and Kalamazoo MSA finally combined for the Battle Creek-Kalamazoo-Portage CSA with a 2010 population of 462,735. This is the only new CSA.

4. Midland micropolitan area is finally added to Saginaw's MSA to form the Saginaw-Midland-Bay City CSA with a 2010 population of 391,569. This up from the former definition of 307,940, which didn't include the Midland micropolitan area.

5. Niles-Benton Harbor MSA in Michigan is added to South Bend, Indiana's CSA.
