  1. They should really just draw one Dem-leaning district across eastern Arkansas. They won’t do that, but they should.

  2. in these four states.  They are in line with 2009 estimates on a county/CD level.

    AR saw the shift towards the NW and that trend has been clear since the early 1970s.  WalMart is in the NW plus the University of Arkansas has also be a magnet for growth.  

    Iowa continued to see a pattern of growth that was stronger in its midsized cities plus Des Moines.  Yes you see some growth in collge towns.  These long term patterns for Iowa and yes the growth is bit more in Eastern Iowa.

    Indiana you see more growth in the middle of the state as opposed to North & South plus slower growth in most rural areas.  Surburban growth is stronger then urban growth. Nothing new there.

    In Maryland you see less growth in Baltimore area then DC area with the outer exurbs growing the faster. Same old same old.

    Indiana and Maryland both had significant growth in hispanic populations as had all the other states.

  3. will be interesting. I posted 2010 population totals for all 99 counties here, as well as a map showing population gain or loss by county. The Republican stronghold areas in rural Iowa are emptying out, especially in western Iowa, the most conservative part of the state. I hope this means some GOP incumbents will be pitted against each other.

    The good news for Iowa Democrats is that the population gains are mostly in counties that lean Democratic in central and eastern Iowa. BUT the bad news is that within those counties, it’s suburban/exurban areas that are gaining the most population. For instance, Iowa’s population grew by about 4 percent over the decade. Polk County (Des Moines and most suburbs) grew by about 15 percent. But the city of Des Moines itself only grew by 2.4 percent. The big growth was in suburbs.

    Cedar Rapids (Linn County) grew, but not as fast as some Cedar Rapids suburbs like Marion.

    Similarly, the biggest growth in Johnson County was not in Iowa City but in in suburban towns like North Liberty and Coralville. Those areas are a bit more Democratic than Des Moines or Cedar Rapids suburbs.

    There should be a huge number of competitive state legislative races in 2012. I could see Democrats picking up a seat or two thanks to redistricting, but I could also see Republicans gaining enough in new suburban-dominated districts to make up for their losses in rural areas.  

  4. Bleeding Heartland user ghbraves checked the numbers for a map he created in 2009 (labeled “G” in this diary) and found that if he moved one small SE Iowa county (Keokuk) from the blue to the green district, his four districts would be within the allowable deviation rate for population (that is, the largest district has less than 101% of the smallest district’s population).

    Map “K” from the same diary is too far off in terms of population. Haven’t checked map “N” yet, or the map Swing State user abgin generated late last year.

  5. I used the Census data just released …


    blue – 762,255

    green – 761,010

    purple – 760,876

    red – 762,214

    ideal pop. is 761,589

    haven’t run the partisan data yet …

  6. Here’s the best I’ve been able to do for Iowa so far in terms of minimizing population variance. The largest district (IA-2) is 100.03% of the smallest district (IA-1).

    This comes at a bit of a reduction in compactness. I tried to make the districts not look like a total mess but there was only so much I could do while keeping the districts as equal in population as I found possible.

    IA Redistricting Plan

    IA-1 (Blue) 761,512: Obama 57.5%, McCain 41.3%

    IA-2 (Green) 761,748: Obama 57.7%, McCain 41.0%

    IA-3 (Purple) 761,555: Obama 53.4%, McCain 45.3%

    IA-4 (Red) 761,540: Obama 47.9%, McCain 51.0%
