Been discussed before, and it was realized that this algorithm really hates keeping cities together.

but you're biases are realizing that. Besides, if you look at the PVI of these districts it tends to represent the state better.

Biases? In favor of keeping cities together? That's not a bias.

A 12-2 result better represents Georgia than a 9-5 result? In a state that was 53-45 in the recent Presidential election?

the median district is close to the state as a whole. And there are three or four RPVI districts the dems could win. 95% of all Georgia republicans are too conservative to win anything below an R+5.

No way that map would survive a VRA challenge anyway.

Split line algorithms, for it to work, need to weigh by population density and be based on travel distance, not distance as-the-crow-flies. I made a longish EffortPost on the topic a few pages back, IIRC.

Neat map though. Make CD's 2 and 3 a vertical split, unsplit Athens, and tweak the metro a bit, and it'd actually have a pretty sensible CoI basis.

Been discussed before, and it was realized that this algorithm really hates keeping cities together.
A different approach would be to split line based on equal area, and then rectify the line to county boundaries, based on placing a county on the side of the line which has the most voters.  Subsequent regions to split would be selected based on their population.   

So for example, if the first split created regions of 3.2 and 1.8 districts, the 3.2 region would be split again.  Splitting would continue until 5 regions were created.  This would form the starting point for further refinement.   Area is neutral with respect to the location of cities, and county boundaries tend to avoid city boundaries, except in metropolitan areas where adherence to county boundaries is difficult.

Is it always bad to split cities?  I'm not saying that cities should be split in such a way that diminishes their power maliciously, but it would seem that there are a lot of cases where a city is better off being the plurality in two districts rather than 100% of the population in one district.  

The polarized situation in Congress, especially the House, is partially a result of cities not being split.  Most of the remaining moderate Republicans live in urban areas where there is no chance of electing a Republican, and moderate Dems in rural areas where the reverse is true.

The opposite of splitting big cities is to create a map like IL. Tentacles extend out from the city well into the suburbs and even to some exurbs so that a population insufficient for 4 CDs has 7 instead. The result does nothing to create moderate districts.



CD 1, 2, 3, 4, 5, 7, and 9 are anchored in Chicago. Population 2.7 M. CD size 713 K.

Yeah!  Let's splice and dice cities, ignore rivers and mountains and county/municipal lines, to hell with metro areas and communities of interest!  Pretty straight lines are all that matters!

Seriously, splitlines are atrocious.  Like, even the worst partisan gerrymanders are better because they at least try to give lip service to natural boundaries sometimes.

NO. Communities-of-interest is the only good thing about FPTP.

Erm, I really don't think the IL map is the "opposite of splitting big cities" at all.  Chicago is split aplenty here.  (And I'd probably quibble with your final observation- I think that 3 and 9 are probably best thought of as anchored in the suburbs with smaller portions in the city.  But that's a nitpick, of course.)

Better examples would be San Fran, Denver, Columbus (which notably was split in three last time around), Louisville, Indianapolis, and such.  None of America's very largest cities are actually unsplit as much as possible.  In many cases, the VRA ensures this even when redistricting is relatively neutral and good-government, as was the case for NYC and LA.

My typo. I meant the opposite of not splitting cities in response to the quoted post that deemed polarization was due to not splitting cities. My IL example was as a counter to show that a heavy split of Chicago into seven pieces resulted in seven partisan CDs, not moderation.

Fair enough, that is certainly true.  Sometimes splitting cities will lead to partisan CDs in one direction, or the other direction, or it will lead to swingy CDs; it all depends on the size of the metro area, its demographics, political culture, etc. 

You could probably say that splitting the largest cities will tend to create partisan D districts, splitting mid-size cities will create swingy, moderate districts, and splitting small cities will create partisan R districts.  But even that's an overgeneralization.

Will someone fill me in on what is so horrible about splitting cities?

Wouldn't said city have more influence if it made up 50% of 2 districts instead of 100% of 1?

The point is having districts that are as demographically/culturally homogeneous as possible, so that the representatives that are elected do actually represent a real community as opposed to an incoherent collection of voters with little connection with one another.

Not that I really care about all this, mind you. I hate single-member districts vote anyways.

This map was intended to minimize county splits while allowing a larger variation of population.



In real life, the two "overpopulated" districts, have a single representative.  Derek Kilmer lives in the portion of Pierce County that is west of the Tacoma Narrows.   And King County which is "underpopulated" has 4 representatives.

That's true, but a city that made up 25% of two districts rather than 50% of one district might have less influence. The fairest arrangement is to try to keep the city intact or split off as little as possible. That avoids both extremes to maximize or minimize influence.
