From this one can also estimate how many counties one should need to expect whole county redistricting to have a range of less than 1%. That limit is about 8.3 counties per district. With fewer counties, the model would predict a range in excess of 7000 or about 1% of an ideal district. The above ME example is a case in point, since it has only 8 counties per CD and has a range just over 1%.

Doh, I was thinking "range" was just the highest deviation for some reason.  That'll teach me to read better.

Can you do Washington(Preserving the acceptable mountain and ferry crossings)? I want to see how bad of a gerrymander 2010 is.

WA can't be done directly with whole counties since there are counties larger than a district. Once I complete the data analysis from those that can, I will suggest a way to extend that to states like WA.

If you missed the lunar eclipse on Oct 8, there's a partial eclipse of the Sun on Oct 23 best visible in central and western North America.

It would be interesting to use the 2011 estimates to see whether maps would radically change from year to year.   And perhaps draw N+1 and N-1 districts.

I think the more interesting question is how rapidly a whole-county district map drawn with best precision become indistinguishable in terms of deviations from a more compact version that started with more generous population tolerances.

New Mexico:



Oregon, Colorado, and Utah can not be done.

I got the green district less spread-out, at least:



-737/+234/+503.

Interesting and the range is smaller, too. Since the purple district gets more spread out, I wonder if compactness is better or worse.

That's actually quite similar to the 1980's map, for what it's worth.



I don't know what standards New Mexico used to redistrict in the 1980's, but there's definitely a precedent for a district stretching from the southwest across the southeast to the northeast.
