Dave's Redistricting

Dave's Redistricting is an online web app created by Dave Bradlee that allows anyone to simulate redistricting a U.S. state's legislative districts.[1][2]

Purpose

According to Bradlee, the software was designed to "put power in people's hands," and so that they "can see how the process works, so it's a little less mysterious than it was 10 years ago." [3] Bradlee has noticed that many citizens are taking this process seriously and using his app to create legitimate redistricting maps that could be put in place. Some websites have called Bradlee the pioneer and cause of the rise of do-it-yourself redistricting.[4][5][6][7]

Dave's Redistricting has frequently been mentioned as a resource that can be used to combat gerrymandering, given that the public has free access to it.[4][5][7]

Political science firms such as FiveThirtyEight have used the website to draw examples of gerrymandered districts, including on their famous Atlas of Redistricting.[8][9]

Functions

Users can redraw the congressional districts for all 50 states with a given Cook PVI. With the use of PVI, any state can knowingly be gerrymandered to favor one political party over the other.[8]

Versions
  • 2.2: This uses Bing Maps, an outdated software that projects the districts of a single state onto a map of the United States.
  • 2.5: After Bing Maps announced that it would no longer be updating for the foreseen future, the U.S. Map feature was removed.
  • Beta 2020: At the end of 2018, a beta version of 2020 was released, again with a type of Nationwide Map feature. This is the first version that does not require Microsoft Silverlight and as such, it can be used in any web browser. The older versions only worked on Internet Explorer and outdated versions of Mozilla Firefox.
  • *The Cook PVI feature does not fully work when using the 2016 election data, only with the 2008
gollark: > I dont and will never understand why people give enough of a shit about people being trans to actually go and complain online ectThe general thing is that some people/groups see some things people do as actively against their moral system in some way. You should probably be able to understand that.
gollark: If people kept mixing them up, it would *basically* destroy civilization. Nobody would be able to tell exactly how much storage their drive had and drive manufacturers would ship them with slightly less capacity than they should have. It would be *anarchy*.
gollark: It should be TiB then, and it would be 256GiB. Correct unit prefixes are important!
gollark: Can they do division? It's obviously a 250GB drive.
gollark: This is why we need my 6D political hypercube model.
