What is UP Atlas peeps. So the title is pretty self-explanatory, I made data based on 2020 population estimates that you can use in DRA. I made these estimates by applying the 2014-2017 rate of growth in each US county for 2017-2020. Then using Google Sheets, I edited each state’s csv file from DRA, applying each county’s estimated 2010-2020 growth uniformly for all vote districts within each county.*

Notes (important!)
  • My growth model is pretty simplistic
  • Growth was applied uniformly across every county, so districts drawn in very populous counties (Maricopa, Harris, etc.) will be less precise. BUT no growth differences in the country are drastic enough such that the districts will be hugely off
  • *The only states where I did estimates by town/municipality are NH, MA, CT, and NJ. The vote districts in these states are actually named by their respective towns, so it was easy to apply town-level estimates.
  • I didn't touch the race population data at all, sorry I didn't feel like doing it. The 2010 data is still there though, so you can still use the race view for drawing minority districts and whatnot
  • I used spreadsheet formulas to calculate all these estimates so there could be some errors. If you find any populations that seem off, pls let me know and I'll look into it!!
  • States without 2020 estimates are AK, WY, ND, SD, VT, and RI, since all are projected to have only one at-large district.
  • I only did 2020 estimates for each state’s main data set, so don’t use any weird data sets like “special voting districts” or whatever.

Directions!
  • First, find the folder named DavesRedistrictingFiles on your computer where all the current 2010 data is saved. If you’ve never loaded state(s) in DRA before, there will obviously be nothing there, so you need to have loaded all the states you want so that the data is loaded and saved onto your computer.
    *You can either use the search function or manually go through the file path. The file path for DavesRedistrictingFiles on my computer (Windows 10) is C:\Users\me\AppData\LocalLow\Microsoft\Silverlight\is\pek0eaig.kln\2gsheg05.vod\1\s\mbcuc5y11hatden4rfah5rjgwlpl3hes2ogfqs2jqmkdx103loaaadaa\f\DavesRedistrictingFiles
    *AppData is a hidden folder, so make sure you have viewing hidden files enabled.
  • Mark this folder in your favorites so you can quickly access it every time you go back and forth.
  • Download the data: I uploaded the 2020 data files, as well as drf template files for y’all to use as a starting point here in Google Drive (it’s SAFE I promise there is nothing shady lol. also I didn’t do a template for California cuz the state kept crashing every 5 minutes and I couldn’t save a whole actual file. TX’s and IL’s files got messed up somehow too so I don’t have them)
  • Copy/cut and paste the data files accordingly into each state’s folder, replacing the old data file with the same name. Then you should be good to open DRA and start drawing 2020 districts! If you already have files from 2010 redistricting (which most people do), you can actually just open that old file, and it‘ll load those shapes into the 2020 data. (drf files simply save shapes, csv files save voting district data) But you'll obviously need to adjust the 2010 district lines for 2020 population equality. For states where the number of districts will change, like TX or PA, obviously you should just start from scratch (or use my templates).
  • If you ever want to go back to using 2010 data for a state, simply delete the whole state’s folder. The next time you load the state in DRA, your computer will download the original 2010 data again.





My take on 2020 districts :3

Using 2016 PVI, there are
  • 205 D-leaning districts (193 with a >1 PVI)
  • 223 R-leaning districts (208 with a >1 PVI)
  • 7 even (34 with a <1 PVI)

mein districts


Trend (change from 2008 lean to 2016 PVI)
(California data wasn't available on DRA, but most districts there trended D)

Florida: gains 2 seats | the way I drew the districts, the new 28th and 29th would be based around Ocala and Sarasota. Almost all of the state is growing pretty quickly, but Miami isn’t growing very fast compared to the rest of the state. Orlando and the exurbs are growing very quickly.

Iowa: Des Moines is growing quickly. Also Iowa City and the eastern cities are growing.

IA-01: Des Moines. D+2 | tilt D
IA-02: rural east. R+4 | likely R
IA-03: urban east. D+5 | lean D
IA-04: west. R+13 | solid R

Kentucky: Lexington, Louisville, and northern suburbs are growing. The west and east are bleeding population. The more KY-04 becomes concentrated around Lexington, the more competitive it’ll get.

KY-01: west. R+21 | solid R
KY-02. Louisville. D+6 | solid D
KY-03: Ohio River suburbs. R+19 | solid R
KY-04: Lexington. R+8 | likely R
KY-05: east. R+28 | solid R
KY-06: south. R+22 | solid R

West Virginia: loses 1 district. I didn’t put much thought into this map honestly, by the 2020s I doubt there will be any actual chance of a Democrat winning one of the seats.

WV-01: north. R+19 | solid R
WV-02: south. (more ancestrally D) R+20 | solid R

Texas: gains 2 seats with 2016-2017-based projections. If it gains 3 then rip I have to make a new map. Most growth is happening in the triangle.
I’M NOT DOING THIS EITHER BECAUSE THE FILE GOT RUINED TOO

Montana: would gain its 2nd district with 2016-2017-based projections. If not then it just stays one at-large district.

MT-01: western cities. growing slightly faster than the 2nd I think. R+4 | tilt R
MT-02: east. (I don’t feel like calculating this but it’s clearly solid R)

Colorado: gains 1 district (southern Denver burbs). might be highly competitive in the 2020s considering high growth and recent trends.

CO-01: Adams+north Denver. D+17 | solid D *majority-minority?*
CO-02: Boulder+Fort Collins. D+11 | solid D
CO-03: west. R+7 | likely R
CO-04: east. R+14 | solid R
CO-05: Colorado Springs. R+13 | solid R
CO-06: south Denver+Aurora. D+21 | solid D
CO-07: west Denver burbs. D+2 | lean D
CO-08: south Denver burbs. R+6 | lean R

Nevada: Almost ¾ of the districts are now entirely within Clark County. The map actually turns out very fair, with 1 solid D seat, 1 solid R seat, and 2 tossups. Again, Clark County is very big so this is probably a little off.

NV-01: Las Vegas D+19 | solid D
NV-02: not Clarke. R+8 | solid R
NV-03: Vegas suburbs, south. D+1 | tossup
NV-04: Vegas suburbs, north. R+1 | tossup

Arizona: gains 1 district (Glendale). Growth is concentrated in the Phoenix area. Districts here won’t be precise like in New Jersey or Massachusetts, so take this with a grain of salt.


AZ-01: northeast, Indian reservations. R+2 | tilt R
AZ-02: Tucson/southeast. R+4 | tossup
AZ-03: southern border. D+9 | solid D *majority Hispanic*
AZ-04: west. R+19 | solid R

AZ-06: Scottsdale. D+2 | likely D
AZ-07: Phoenix. D+23 | solid D *majority Hispanic*
AZ-08: northern exurbs. R+15 | solid R
AZ-09: Mesa/Chandler. R+4 | tossup
AZ-10: Glendale. R+1 | lean D

Oregon: gains 1 seat in the Portland suburbs.
This is technically a 3/3 map in terms of PVI, but half the districts are very competitive. If I’m not mistaken, Oregon’s Democratic incumbents are all pretty popular, so this could actually end up being a typically 5-1 D delegation lmao.

OR-01: northwest/Portland burbs. D+6 | likely D
OR-02: east. R+10 | solid R
OR-03: Portland. D+31 | solid D
OR-04: south. R+2 | lean R
OR-05: central. R+2 | tilt R
OR-06: Portland burbs. D+2 | lean D

Issue:



This is the projected 2020 apportionment changes. These projections show a confidence level beyond the margin of error too with regards to the difference in priority value between seat 435 and seat 436. Your projections seem to not line up with this.

2020 is still years away...different growth rates result in different apportionments

The Census Bureau produces population estimates for congressional districts based on the ACS.

How close do these match the current districts using your estimate data?

It has a pretty significant R lean that should probably be corrected.

Minnesota: loses 1 district (most of current 7th). The Twin Cities metro area is growing healthily. The rest of the state not so much.

MN-01: south. R+5 | likely R
MN-02: south suburbs. R+1 | tossup
MN-03: west suburbs. D+3 | likely D
MN-04: north suburbs. EVEN | tossup
MN-05: Twin Cities. D+30 | solid D
MN-06: central. R+15 | solid R
MN-07: north. R+4 | likely R

Not going to happen. Even the Republicans don't want to combine the Twin Cities anymore.

How do you envision the post-2020 map looking like?

It has a pretty significant R lean that should probably be corrected.
respectfully diagree. I actually was thinking of Ds much more than Rs when making all the maps due to their geographic disadvantage, it just shows how difficult it is to get an even breakdown. Good examples are Pennsylvania, Oklahoma, Wisconsin, Kansas, Nebraska, etc. In my OK map I put Norman with OKC instead of just doing a whole district within Oklahoma County, and even then it’s still R+4. Only Massachusetts, Washington, and New Jersey favor Ds disproportionately on the D side tbh.

Republicans only lead by a narrow 15 seats when counting >1 PVI seats. And that’s based on 2016 PVIs! This is for the next decade and a lot will change. There are plenty of narrowly Republican districts that have trended hard D recently (TX, CA, AZ, NC, GA), while there aren’t as many on the D side. By the 2020s I’d expect this to be closer to even (it already is quite close)

I would never have them together in an 8-seat delegation but MN’s most likely dropping to 7. It just seemed to work out well that way, there’s a suburban Carver+Hennepin and a suburban Scott+Dakota+Washington county, which make sense. And Minneapolis+St. Paul kind of does make sense, it’s highly urbanized and diverse. Those two suburban seats would probably be tossup seats at worst for Democrats in the 2020s, making the general breakdown 3R-2D-2E at worst. Not too shabby considering MN leaned Republican in 2016
you’re prob not wrong about it not happening though. I’m just stating my case

The Census Bureau produces population estimates for congressional districts based on the ACS.

How close do these match the current districts using your estimate data?
um do they have 2020 estimates? i mean i just looked at the 2016 estimates for new jersey's districts, and it matches up with my 2020 estimates in terms of growth patterns - northeast areas overpopulated, southern underpopulated

Issue:



This is the projected 2020 apportionment changes. These projections show a confidence level beyond the margin of error too with regards to the difference in priority value between seat 435 and seat 436. Your projections seem to not line up with this.
2020 is still years away...different growth rates result in different apportionments
The projections I found show a difference in priority values for seat 435 and 436 beyond the margin of error with just 2.75 years out. There is no way your projections should be any different unless you are using incorrect data.

there are multiple projections showing a battle between MT-02 vs. TX-39 depending on future growth

According to my calculations, AZ-10 is seat 435, and MT-02 is seat 436, with the difference between the 2 priority values beyond the margin of error.

thank u <3 if you wanna give your own go at drawing districts imma upload the files soon today. The way I drew AZ, yes, kind of, but not necessarily cuz it wouldn't be super hard to gerrymander it for Republicans. Maricopa is likely trending D, so we'll probably see medium/light R areas shifting toward tossups/D-leaning districts. I would say MA is the worst state for Republicans, even with hard R gerrymandering you would still only get a tossup/very competitive district. And you could argue TX is becoming hostile territory with its D-trending suburbs and self-packed ultra Republican rurals (though again, you could still gerrymander)

well that's your calculation you/I could just draw a 39-district map for that situation

also everyone plz actually use the data once I upload it DKJFKSD I didn't do all this work for nothing

In my opinion, keeping Ramsey County, Minnesota whole should be high priority.

How do you access the new numbers?

Also, it looks like the current FL-25 is destined to flip next decade. Only a matter of time. Same with MN-7/8 too. Also, NV-3 should become much safer with Clark County being able to support virtually all of three CD's.
Gotta disagree there with MN-07/8.

This is a possible alternative - though it would have to be tweaked based off 2020 census numbers.
MN-01: 51-46 Obama, R+4.86
MN-02: 50-48 Obama, R+1.44
MN-03: 53-46 McCain, R+6.72
MN-04: 61-37 Obama, D+11.7
MN-05: 71-27 Obama, D+23.56
MN-06: 53-45 McCain, R+13.79
MN-07: 54-43 Obama, R+3.57

Based off 2017 census estimates...MN-01 has 769,492 people, under quota by around 27,000 people. Add Brown County in and now it's within range. this makes it R+5.22, and 50.9-46.7 Obama.
MN-02 has around 814,700 or so people. It is over quota by 17,000 people. If it cedes Cedar Lake, Helena, and Sand Creek townships in Scott County, it is within quota. It now is R+1.15, and 50.6-47.5 Obama.

read the directions in the op (basically find DRA folder on computer, download the files, then paste files into state folders)
let me know if you run into any problems
