Million Member Districts

[President Punxsutawney Phil]

Deviation is +/- 5% in order to give more leeway to eliminate county chops. Apportionment is based off a simple formula: (2010 census population for a state divided by one million; the resulting number is rounded to the nearest integer that is larger than 0)
County splits are discouraged and must be avoided when practicable.
Maine and Nebraska are errors on the map; in reality Nebraska has 2 seats, and Maine has 1.

excellent work ASV.

Oregon

District 1 D+05.79 - 57.3 - 40.7
District 2 R+12.61 - 42.8 - 54.9
District 3 D+21.49 - 71.6 - 26.3
District 4 D+02.31 - 55.9 - 42.0

Poor Clackamas County.

Two ways one can do Oregon without any county splits.

Louisiana

District 1 R+20.27 - 30.2 - 67.8
District 2 D+21.45 - 69.3 - 29.6 - 59.8 African American
District 3 R+18.55 - 35.2 - 63.1
District 4 R+11.51 - 40.1 - 58.9
District 5 R+24.69 - 26.3 - 72.0

That split of Natchitoches Parish is unnecessary. I allowed +/-5% deviation for a reason.

I don't like this obsession with county splits over natural geographic boundaries. The second map makes the most sense, but split along the Willamette River in Portland. The Multnomah-Columbia/Washington-Clackamas loop is absurd, and the mixing of chunks of the Willamette Valley is just a bad idea.

This may have become just a quasi-suggestion at this point - but eh, I wish more heed to paid to it.
The configuration in my second map is also quite logical - Portland's suburbs are largely in one seat. It's unfortunate that the Portland seat has to loop around it but in 2020 it's likely that that seat would get more logical, with Multnomah possibly getting a seat to itself.

some advice: don't leave VTD boundaries on when doing screenshots. I once did that and I learned the hard way that it was a bad idea.

150 D leaning seats, 15 EVEN, 152 R leaning

Have you ever considered using this template?

I don't use it. It's too big.
I also have lots of experience using my familiar template. I am kind of conservative on these kinds of things - if it ain't broke, don't fix it.

[President Punxsutawney Phil]

Another issue is that even I did use it, it would be slow on my old desktop computer, and I don't want to tire that thing. It's a workhorse, but it's an old workhorse.
I have used a similar template on there for an Multi-Member District project of sorts and the computer had problems with speed and editing. It gives me no problems with my typical template that is smaller.

[President Punxsutawney Phil]

It would be interesting to see you attempt another project with something between 500,000 and 700,000 people per district.

Any response?

That's rather well-trodden territory, no?

Do you all still have the DRF files for this somewhere?

The Drfs in some cases are in fact not necessary. Note how I go with all full counties in many states.
However, which states do you wish to have the drfs for?

I wanted to see what the 2010s set of maps would look like under 2020 results. I chose Arkansas as a prime example.
2010s I had:
AR-01: every county bordering Mississippi and every county bordering Louisiana; every county bordering these counties except for Poinsett, Craighead, and Little River; and Clark, Dallas, Cleveland, Jefferson, and Pulaski (973,891)
AR-02: everything that is not in AR-03 or AR-01 (976,048)
AR-03: Crawford, Independence, Benton, Poinsett, everything north of Cleburne County (965,891)

These districts in 2020 have populations of 998,503; 927,778; and 1,085,243 respectively. AR-01 voted for Biden by 1.1 points (49.1-48.0), and Trump won AR-03 66.0-31.2 and AR-02 71.4-25.9.

One can equalize the populations (roughly) by transferring Lonoke County into AR-01 and Crawford and Jackson into AR-02.
That would render the populations as the following:
AR-01 1,001,376
AR-02 1,001,793
AR-03 1,008,355

Oregon, 2010s (2010 population/2020 population)
OR-01: Multnomah, Columbia, Clatsop, Tillamook, Yamhill (945,796/1,044,201)
OR-02: Washington, Clackamas, Hood River (928,419/1,045,750)
OR-03: Marion, Polk, Lincoln, Benton, Linn, Lane (990,148/1,090,513)
OR-04: everything else (966,121/1,056,792)

Unlike in Arkansas, population growth is evenly spread out. In fact, deviation seems to decline from 2010 to 2020 (considering how the space between 1, 2, and 4 shrinks).

While everything is within deviation, Hood River County can now be moved into OR-04. That would change the population of OR-02 to 1,021,773 and OR-04 to 1,080,769.

It's unfortunate that the state doesn't yet have 5 seats. I will make a 5 seat map now to see what would be possible if that was reached.

How does Nebraska get 5 seats?

Oh. Thanks for discovering a transcribing error.
I had ME and NE in a separate bucket. Since NH is next to ME, I ended up changing NE to NH. Which in turn lead me to accidently placing "NE" and "ME" and the "ME" to "NH".
NE only has 2 seats, and Maine only 1. For now.
