Here's version 2 of my draft plan. In addition to the population I have included the PVI of each district in square brackets, with positive values for D PVIs and negative numbers for R PVIs.
Mackinac (MI) 3400K [-4.2]
Huron (MI) 2620K [+3.6]
St Clair (MI) 3864K [+10.6]
I have it:
Eastern Michigan 2720
You may have displaced the population from Lenawee.Alternative Names
The Great Lakes State
I would let Jackson and Hillsdale switch districts. While this does drop the population for Eastern Michigan and make the border more irregular, I think that there may be a Jackson-Battle Creek-Kalamazoo linkage.History
Michigan gained its second representative in 1860, and its 3rd in 1890. Initially it barely held onto the 3rd, but with the development of auto industry easily maintained its 3rd, and gained a 4th in 1950. It lost the 4th in 1990.
Michigan was the 7th largest state from 1920 to 1970, and has been 7th, 8th, or 9th, since 1880, passing Kentucky, Indiana, Missouri, and Massachusetts during the past 130 years, while falling behind California, Texas, and Florida. But Michigan will likely fall to 10th in 2020 as Georgia and North Carolina surpass it.
Thanks for the catch. I'll update my PVIs as well.
Jackson is sometimes placed with SE MI and sometimes in a greater Lansing/Mid Michigan region, but I've never seen it thought of as part of an extended Battle Creek/Kzoo area. Hillsdale is less glued than Jackson, but seems more likely to stay with Jackson than not. Looking at Mid Michigan, it's clear that Gratiot and Isabella (with Central MI U) should shift to go with Lansing and the Tri-Cities.
