Well, look what HE's doing to US now...

[muon2]

The population of 100,000 is very close to the size of a representative seat in the IL General Assembly. States are more akin to European countries in size. So, the size of these districts doesn't match well for the US as a whole.

[muon2]

Muon: See the first post. Just before the smilie.
Immy: Coming soon.
WMS: Your job.

My point was that your exercise might be more useful if assigned to the state legislatures, rather than to the federal government.

[muon2]

Your system makes a case for a single state of Dakota (pop 1397 K, 14 seats).  

NORTH DAKOTA
642K inhabitants, 6 seats

When you get to IL, within Chicago the easiest subdivisions are for "Community Areas". These are equivalent to groups of census tracts and are all named by their neighborhood. If you don't have the data, I can get it to you.

[muon2]

For decades Chicago has been divided into community areas that now coincide with groups of census tracts that have summary data collected for them. In terms of census data they area at an equivalent level to townships. The Chicago Community Area Data can be found at the City of Chicago's Department of Planning and Development.

The url for the page with the map is map page

The population data can be looked up on this page: pop page

If you want my suggestions on the division into 100 K units I'll be happy to oblige.

[muon2]

Cool.

Thanks. I had some idle moments at work so I took care of this, using my unfair advantages of a decent connection, lots o' storage space, and good Arc programs (although it is possible for anyone to do this with free software such as ArcExplorer). I have no idea how I'm going to divvy up Albuquerque's 5 seats, since the precinct lines don't necessarily follow the boundary between Bernalillo West CCD and Albuquerque CCD (don't get me started on the precinct boundaries...).

And to Muon2: please, condense those links - they're stretching the screen. Easiest way is to do it like this:

{[}url=http://{whatever the link is}]{text in place of the link such as Neighborhoods}{[}/url{]} And remove the {}.

I thought that URLs couldn't be embedded if they contained an = character. That used to be true on the site, but if it's changed let me know and I'll make the necessary corrections.

It's worked pretty well for me having the url= the link - in fact, I think the code requires the = to be there for this to work.

I've fixed it now. One of the upgrades must have fixed this from a year ago. The problem was not with the url=, but with an url that have an = within it. In any case, it's no longer a problem.

[muon2]

Tap, tap, tap, ...

Must be IL next. I've spent some time in anticipation thinking how I would do it. But, I'd like to see your view first.

[muon2]

Not too far off my split. I'll highlight some differences with my comments in my next post.

My big picture split goes along these lines:
Chicago (except O'Hare) + Norwood Park: 2908 K, 29 seats.
N. Cook (except Maine Twp) + Lake + McHenry: 1816 K, 18 seats.
W. Cook (with O'Hare and Maine Twp) + DuPage + Kane: 2076 K, 21 seats.
S. Cook + Will: 1291 K, 13 seats.
Rest of the state: 4328 K, 43 seats.

I kept Boone outside of the Chicago collar counties. McHenry + Lake add up to almost exactly 9 seats, and Winnebago + Boone + DeKalb add up to 409 K for 4 seats.

[muon2]

My thoughts in color. The districts are rearranged in order as well.

NORTHERN REGION, 998 K, 10 seats

DeKalb, Boone and Winnebago add up to 409 K for four seats, most of the population of Boone in the Rockford metro area.

IL-82 DE KALB
