Michigan state law says that the district in the southeast corner of the state must be the highest numbered district. Yet we have 14 districts, and the one in the southeastern corner is the 7th, and the real 14th is the 4th closest to the southeast corner. It would make more sense if they were renumbered like this:
District 1 (Bergman's district) stays the same
District 2 (Huizenga's district) becomes District 3
District 3 (Amash's district) becomes District 7
District 4 (Moolenaar's district) becomes District 2
District 5 (Kildee's district) becomes District 4
District 6 (Upton's district) stays the same
District 7 (Walberg's district) becomes District 14
District 8 (Bishop's district) becomes District 10
District 9 (Levin's district) becomes District 8
District 10 (Mitchell's district) becomes District 5
District 11 (Trott's district) stays the same
District 12 (Dingell's district) becomes District 13
District 13 (Conyers's district) becomes District 12
District 14 (Lawrence's district) becomes District 9
California requires districts to be numbered north to south. In the past, they were numbered in a sort of a zigzag pattern, but the redistricting commission was convinced to number them based on their northernmost latitude. Thus the districts are now all scrambled, as they jump from a district in LA to a district in San Bernardino, etc. The district including the Owen Valley is numbered as if it were a northern district even though most of the population is in San Bernardino.
Surprisingly, the northern boundary is neither a straight line, nor an arc of latitude. If you have a detailed map, you can find the bump in District 1 (all three maps)
