GAMERS ALERT: Free Online Redistricting Mapping Software Let's You Help Shape Alaska's House And Senate Districts [Updated]

An email [it's copied below] for Alaska Redistricting Board update subscribers today says that they have worked out an agreement with Tufts University for maps making tools for the public to use.  [You can subscribe to the Board's updates here.]

The 2020 detailed census data are not out yet, but people can start practicing with the 2010 data now. Below is the email with a link to the software and two example maps.  

I haven't tried this yet because I wanted to get it out to people immediately.  For anyone interested in mapmaking or in politics, this is a must.  It's a good opportunity to get non-political tech people paired up with non-tech political people.  

I hope gamers see this as a real life game and that they can keep the Redistricting Board accountable by showing them that better maps (maps that meet all the Federal and State requirements more efficiently and equitably) can be made.  When there were challenges to the Redistricting Board's maps in the 2010 round, maps were submitted to the courts to show that better maps could be made.

As I looked at the example maps below I realized there are some requirements for valid districts that mappers need to know. Here's an early post from the 2010 Redistricting round that details some of the Federal and State requirements.  For instance, 

The Federal Constitutional Redistricting Principles are, briefly:

• A.  "One Person, One Vote". . ."legislative seats must be apportioned exclusively on the basis of population and the populations of the respective districts must be substantially equal."
• B.  "Districts of as nearly as equal size as practicable.  Maximum overall deviation of the no more than 10%, (i.e. plus or minus 5%)  Deviation is the measure of how much a district or plan varies from the ideal.  Good faith efforts to make deviations as small as practicable must be made. 

There are forty House seats.  Each has to be as close to equal as possible.  

The official 2020 total Alaska population which is  733,391 divided by 40 = 18,334.775.  

But it's impossible to have a fraction of people in every district, so it's necessary to have some deviance.  .  Ideally, each district deviates from 18,335 by less than 1% (That would be 183 people). 

But while mappers have to get all the districts equal, they also have requirements for compactness and for "relatively socio-economically integrated areas"   That's why some districts can deviate up to 10%, though that is discouraged.  Urban districts with lots of population should be under 1% deviation if possible.

So here's an enlargement of the first map below.  It's pointing to "percentage of deviation from the ideal"  That should make sense to you now, but let me repeat the details again.

Population Balance refers to the fact that every House district has to be as close to 1/40 (there are 40 house districts) of the official 2020 total Alaska population which is  733,391 divided by 40 = 18,335.  

I'm confused by the numbers in the red circle.  It says percentage, and 8.860 percent is under 10%.  But I don't know why it has a comma instead of a period.  I have an email into the Board to clarify that.  It could just be the way that software handles percentages.  I'll update this when I hear back. [UPDATE July 22, 2021:  Yes these are numbers and if I had read the note more carefully, I would have realized you need to hove the cursor over the numbers to get the percentage of deviation.]

Now, here's the email:

"Good morning subscribers,

Thanks for your continued interest in Alaska’s redistricting process. Census data for 2020 is expected in late August and the Board is looking forward to getting to work.  Drawing maps will be challenging and public feedback is an essential part of the process. 

 

One of the ways you can provide input is by sending the Board your map ideas. To facilitate this the Board is working with The Redistricting Lab at Tufts University to deploy a customized, web-based, publicly available map drawing tool.  This platform is available now for your beta testing at: 

https://www.akredistrict.org/create/

REMINDER: the data and blocks shown are from the 2010 Census; the 2020 data will be uploaded in late August – we’ll send out a notice at that time. Any maps you create until then will be based on 2010 population data and so are not appropriate for formal submission to the Board.

The web mapping tool uses a "paint brush" concept (for coloring) to shade in areas you wish to assign to a district, which are denoted by 40 individual colors.  This customized version allows painting at the Census block level, the most precise level of geography available and the same one which the Board will use to draw new legislative districts.

As you "paint" a district, the population will be dynamically totaled under the Population tab.  To assist you, under the Data Layers tab you'll find tools to overlay the state with existing legislative district boundaries, incorporated city limits, borough boundaries and school districts.

If you would like to view population distribution you may make selections to shade Census blocks with population density under Data Layers -> Demographics -> Population.

The system supports undo/redo, and allows you to "lock already drawn districts". This enables drawing perfectly adjoining districts by respecting blocks you have already colored into a previous district.

Use the Save/Update button to save your work, share plans with others (copy and send the URL) or submit directly through the website for Board consideration (once we have gone live with 2020 data, expected at the end of August).

Please take a little time to experiment with the tool so we can identify any bugs prior to our public launch. Your feedback would be appreciated; simply reply to this email.

Thanks,

Peter Torkelson

P.S.  Here are a few tool tips to get you started:"   [Below are the two example maps that were at the end of the email.  You can enlarge them considerably by clicking on them.]
