Fair redistricting: Illinois

[Torie]

Sol's map wins for Kentucky!

Were the results published somewhere?

would you like me to make a spreadsheet of all the state votes?

Yes.

kk i'll make it over the weekend (super busy this week )

What's the status of the KY results? I have more than a passing interest. I'm involved with some graduate level academic research on redistricting algorithms, and any feedback about which maps were preferred over others may find its way into that research. Even better would be comments about the maps, but that doesn't seem to be the way panelists want to react. Of course if people want to say why they voted for a particular plan, I'll dutifully make note.

On a side note: Shouldn't Sol be moved into the open Dem spot? Then a Pub or at least an indy would take the second R spot.

The KY maps are all so similar, that it is hard to generate much passion about which map is best. The Sol and Muon2 maps appear to be  almost identical, except that Sol has more chops to get down inequality (not my bag, but that is a matter of taste), while the Jimrtex has some extra erosity that appears not to really be necessary (with that jut into Laurel County looking particularly unfortunate).

Here is mine. I am not sure what CD in Muon2's map is an "e," using the DRA PVI numbers. I have the usual 7R and 2D districts. I am also not sure he followed the subunits in Marion County, if those subunits are the former towns plus the inner city of Indianapolis prior to Mayor Lugar doing unigov for Marion County when I was an adolescent. I did follow those subunits, although it required two non contiguous chops. I have a pack penalty for the Indianapolis UCC.

If one desires commentary on these maps, it would help if for each state, they were all collected in one place in a series of posts, or one post. As it is, I find the process so chaotic, that I kind of backed away from it all.

As a general rule, I give a lot of weight to the pack and cover rules, and dislike maps that chop up metro areas with abandon. I saw some maps of Ohio that chopped the Columbus metro area to bits.

Curious Question Muon2, is it possible to have only a single County split, while also having a District entirely within Milwaukee County?

Probably not, since his one chop is butt ugly,  so if he could arrange the other counties is such a way that that the chop into Milwaukee county was far smaller, but that population shift would not cause a chop elsewhere (the odds of that sized number of folks being moved around, to accomplish a specific goal and not causing a chop elsewhere are low in any event), he would have done so.

In terms of salience in one's brain, I do think rural counties matter a lot more than urban ones. Heck even the little town[ships] matter. In Columbia County people make a fairly big deal as to what town they live in. Part of that might be that everybody knows personally the government officials in those towns.

Kansas Non-Partisan plan.

My nonpartisan redistricting plan for Kansas splits only one county.

District 1 R+25.56 - 30.1 - 68.1
District 2 R+09.19 - 45.8 - 52.2
District 3 R+03.64 - 48.8 - 49.9
District 4 R+14.92 - 39.9 - 58.3

I believe I once drew this exact map. It's the BEST!

Here is my Missouri effort. It has three county chops, with one macro-chop in St. Louis County.  It has no pack or cover penalties for multi county metro areas. The Pub Skew is 1.

Addendum. I modified the chop lines in Jefferson County. By doing that I avoided under the Muon2 rules an erosity penalty point, by having the county seat (Hillsboro) sit in MO-02 rather than MO-03, which avoided three road cuts from Hillosboro to the county seats of the two counties to the south, and St. Louis County to the north (which would have to leave MO-03, and go through MO-02 to get to MO-08, or MO-01, where the county seat of St. Louis County, Clayton, sits), while generating two road cuts to the county to the SW and to Franklin County to the west, for a net of one less road cut and penalty point. Another trick is that the population needed by MO-03 is about 35,000, which is a tad less than a macro-chop. So you want the chop to be in Jefferson County, rather than St. Louis County, which is already macro-chopped, and any new CD chopping into that county is also a macro-chop, no matter how small. Macro-chops generate a lot more erosity penalty points, because road cuts are counted for each sub-jurisdiction, typically generating multiple road cuts and penalty points.

So the Muon2 rules tend to force this kind of map, to minimize the erosity penalty points, and avoid cover and pack penalties. The excess population of the St. Louis metro area (in addition to the two CD's already nested in it) needs to be all in one CD (here MO-03), as is true with the Kansas City metro area, which forces, all things being otherwise equal, the CD that contains Kansas City to take in the entirety of the county to the south, to avoid that county, or part of it, being in a third CD, with the second CD taking in the two counties to the north.
