How many people would that equal per district?

roughly 500,000 in general though it varies per state, and there's a +/-10% deviation in use.

So how many seats would each state get? I can try to make the New England onrs

I respectfully decline, because 1) this is designed to be personal challenge of sorts for me, and 2) I already have a rough idea of how New England's seats will look like.

oh oh oh! Can I do SC? Pleeeeeease?


If your answer is yes...
How many districts would it need?

This is my challenge though. Giving anyone else the leeway to do any states only hurts the challenge.

That is a terrible way to draw West Virginia into 4 Districts.

I split 0 counties and I created compact districts. I also kept the coalfields whole.

It is possible to split 0 counties and create compact districts in this scenario without making them look so ugly.

How can they possibly be seen as ugly?

Indiana next please!

I'm moving east to west so Indiana is likely to be one of the states up soon. Florida, Alabama, and Indiana are the most easterly states I haven't done yet. Those three along with Mississippi and Wisconsin are the only states east of the Mississippi so far unfinished.

I split 0 counties and I created compact districts. I also kept the coalfields whole.

How can they possibly be seen as ugly?

For starters, this is a very neat District for Southern West Virginia with only a 56 person deviation:

Going with such a district creates a very long district running alongside the eastern part of the state, OR it puts Kanawha and Greenbrier Counties together. Neither is good for compactness/CoI. The way I did it is not ugly - it creates districts that are kind of boxy but that's just one way it can be done. And I quite like the districts the way they are. You still haven't really justified your claim that the map is "ugly".

I really don't like the western NY districts either. You split the Buffalo suburbs between three districts,  divided the Southern tier between different districts, and drew Niagara so that it contains parts of two metro areas. Those borders don't really represent the communities of interest around here very well.

If that's the case, that's because I am trying very hard to avoid county splits, the size of the seats themselves (which are less than 75% of RL CDs, which forces more CoIs to be split), and because the Rochester seat itself is drawn using a natural border. Erie+Niagara is simply too big for 2 districts, so I had to create an obligatory Buffalo-centric seat, an Erie seat, a Rochester seat, and a district combining exurbs/suburbs from both metros.
The geography and population distribution is just too awkward to keep Buffalo suburbs within just two seats, maintain compactness overall, have a reasonable Rochester seat, AND have minimum county splits. I was also hemmed in by the districts drawn in the Hudson Valley, so I had less room than usual to use greater deviation as means to keep CoI together.
