Dave's Redistricting App

[minionofmidas]

I plan to get all the new 2010 census data when it's available (Feb-Mar).

Great!

Thank you for your wonderful redistricting app

I've just done an Arizona map.

All states but Iowa and Wyoming are on ACS figures for the block groups now. (Which means it makes sense to use these rather than the Voting Districts in the future.)

[minionofmidas]

Did you include Norman?

OK, I know this has been asked and answered many times before, but...how do I save a map? I've got an Ohio I'd like to share.

Either click "save view" or just do a screenshot.

As of Census 2000, Omaha has only one minority-majority seat in the Unicameral - the 11th. . That however was 72% Black, 20% White. It's conceivable that no. 7 is majority hispanic now - in 2000 it was 58% White, 32% Hispanic.

In the map above (with 2005-9 ACS data), I drew three. And none of them has any major lily-white areas slapped on just to make the numbers, something I always find distasteful. Most of the blocks around their edges are majority white, but they are mixed.

The 7th-like seat in the southeast corner is 57% Hispanic, 35% White, the pale red seat is 51% Black, 32% White, and the grey seat north of it is 50% Black, 41% White. The ugly tan thing between them is 76% White, 10% Hispanic, 7% Black.

Arizona '10 is up! (And a lot of other states, but I'd been waiting impatiently for Arizona.)

Expand the area views section. You'll find a button titled "save view as jpg".

Or use screenshots. That's what Torie does.

Heh, I managed to draw a 51.9% Obama district in Oklahoma. Zig-zags across the state and back taking in every remotely Democratic precinct.

Color by election is a wonderful tool:



53.4% Obama. 52.0% White.

2008 election data has been added for Kansas, Mississippi, Vermont, and Wyoming. Exciting, I know.

I could see uses for three of those!

57% Dem district in Kansas by removing the more Republican parts in Johnson and adding Topeka to the 3rd.

[minionofmidas]

Also, Wyoming has 60 LDs, not 30. 30 SDs, 60 HDs. And a nesting requirement (well, not sure if it's a requirement, but they do it anyways.) And a bizarre numbering scheme that doesn't reflect that in the slightest.

Two Democratic districts in Kansas. You could probably do without the southeastern leg entirely as the 2nd is 52.9% Obama, but I was happy to finally have the populations right. (I still have it open... I think I'll do it.) I'm pretty sure you can't do it without Wichita, though maybe it's just about barely possible on a super-contorted map. The third district is 49.5-49.1 Dem.

[minionofmidas]

Much better.



Still 52.6%. 3rd now at 49.9%.

And you only had to go from Missouri to half-way to Colorado.

I did that, but I didn't have to, as you can see in the 2nd map below. Happened because I was drawing from a 2nd district basis, of course.
Also, of course, the first district still goes all the way to Missouri in these maps.

[minionofmidas]

Only because the map is chopped.

[minionofmidas]

1st distict San Jose town and eastern suburbs, 2nd western and southern suburbs with a little extension along the coast, 3rd eastern and southeastern parts of the island, 4th southwest with the cities of Ponce and Mayaguez, 5th (okay 0th) northwest. 1st to 3rd all within 4 of ideal population, 4th 68 under, 5th 61 over.

[minionofmidas]

It probably crashed because so many people were trying to download New York at the same time.
