The Trond can't help it...

I'm redistricting again... based on these rules now:
"Section 26, Article III, of the Texas Constitution requires that house districts be apportioned among the counties according to the federal census population and the following rules:

  (1) a county with sufficient population for exactly one district must be formed into a single district;

  (2) a county with a population smaller than the population needed for a whole district must be kept whole and combined with other contiguous counties to form a district;

  (3) a county that can hold a multiple of whole districts must be divided into that number of districts, with no district extending into another county; and

  (4) each county with a population sufficient for one or more whole districts plus a fraction of another district must be divided into that many whole districts, with the excess population added to other adjacent counties to form an additional district.

In practice, it is sometimes impossible to draw a statewide plan that completely satisfies these rules while maintaining districts with equal populations. The Texas courts have allowed a house plan to violate these rules to the extent necessary to draw a plan that complies with the one-person one-vote requirement."

Texas allows for up to 5% deviation from the average. While reasonable, such a deviation would never pass the SC's muster. I'm going with a two-part rule on this...
The maximum deviation allowed (from the state average) is 2.5%. If this is not attainable, additional county splits will be introduced.
A deviation over 1% is accepted only if there is NO alternative configuration of counties that results in a lower deviation.
After additional county splits, the deviation needs to be less than 1%.

Plus some rules on contiguity...
In case of doubt (borders across lakes or sounds), I decide which counties are contiguous and what is not.
Counties or county equivalents wholly included within another county (cough Virginia cities) may be treated as part of the surrounding county.
The separate parts of noncontiguous counties (cough Norfolk MA) are to be treated as separate counties.

Just like in the TX House, these rules are going to end up with some funny-looking districts, btw.

Maine

1 York, Cumberland, Androscoggin, Oxford, and Franklin Co.s
640,369 (1.005)
2 remainder
634,554 (.995)

New Hampshire
1 Rockingham, Strafford, Carroll, Merrimack, Belknap
625,808 (1.013)
2 Hillsborough, Cheshire, Sullivan, Grafton, Coos
609,978 (.987)
Much as I dislike this map (basically a cleaned-up version of the current one), this is the minimum possible deviation with no split counties.

Massachusetts

1 ca. 92% of Suffolk Co
ca. 637,873 (1.005)
2 rem. of Suffolk Co, coterminous part of Norfolk Co
ca. 637,874 (1.005)
3 ca. 88% of Essex Co (minus Southwestern portion)
ca. 635,308 (1.001)
4 ca. 43% of Middlesex Co
ca. 635,309 (1.001)
5 ditto (leaving narrow strip along Southern perimeter)
6 ca. 85% of Worcester Co (minus Southern portion)
ca. 635,309 (1.001)
7 remainders of Essex, Middlesex, and Worcester; Brookline; 39% of Hampden Co (eastern portion)
ca. 635,308 (1.001)
8 Berkshire, Franklin, Hampshire, and 61% of Hampden
ca. 635,309 (1.001)
Notice the additional county split
9 Plymouth Co, Cohasset, and 28% of Bristol Co
ca. 630,749 (.993)
10 Barnstable, Dukes, Nantucket, and 72% of Bristol Co
ca. 630,749 (.993)
Notice the additional county split (alternatively, Barnstable or Plymouth, rather than Bristol, may be split)

Rhode Island
1 82% of Providence
ca. 524,160 (1.000)
2 remainder
ca. 524,159

Connecticut
1 79% of Hartford
ca. 681,113 (1.000)
2 New London, Middlesex, Tolland, Windham, 3% of Hartford
ca. 681,113
3 83% of New Haven
ca. 681,113
4 77% of Fairfield
ca. 681,113
5 Litchfield, 23% of Fairfield, 17% of New Haven, 18% of Hartford
ca. 681,113
Notice the additional county split (remainder of Hartford - or alternatively of New Haven). Without it, D2 would be at .968.

[minionofmidas]

New York City Area (upstate not even started yet, and won't be done today)
I've decided that Suffolk is adjacent to Westchester - this little bit of magic makes it possible to have no additional county splits!
1 & 2 46% of Suffolk Co (missing portion in NW)
ca. 657,395 1.005
3 & 4 50% of Nassau Co
ca. 667,272 1.020
5 - 7 30% of Queens
ca. 670,672 1.025 (just under that to be precise)
8 - 10 27% of Brooklyn
ca. 670,672 1.025
11 19% of Brooklyn, 10% of Queens
ca. 670,673 1.025
12 & 13 43% of Manhattan
ca. 660,308 1.009
14 14% of Manhattan, Staten Island
ca. 660,307 1.009
15 & 16 50% of the Bronx
ca. 666,325 1.018
17 71% of Westchester Co (missing portion probably along S perimeter)
ca. 657,396 1.005
18 8% of Suffolk Co, 29% of Westchester Co, all of Rockland Co
ca. 657,395 1.005

The alternative ("Plan 2") would be
1, 2 in Suffolk; 3, 4 in Nassau; 5-7 in Queens; 8-10 in Brooklyn; 11 remnants of Suffolk, Nassau (a very narrow strip), Queens, and part of the Brooklyn remnant; 12 Staten Island and remainder of Brooklyn remnant; 13, 14 in Manhattan; 15, 16 in the Bronx; 17 in Westchester Co; 18 remnants of Manhattan, the Bronx (a very narrow strip) and Westchester, plus not Rockland but Putnam.
This has two very ugly districts and an additional county split (in Brooklyn), but also has the benefits of not bending the rules on contiguity and of having better population balance - all those oversized Queens and Brooklyn and Bronx and Nassau County districts in plan 1 will have to be mirrored by undersized upstate districts.
A final decision on which map to use is possible only after I've done the upstate, obviously.

I've decided that Suffolk is adjacent to Westchester

In what Bizzaro reality is this happening?  Suffolk is in no way adjacent to Westchester, even if you account for water boundries.

What's more, the average of the 11 other constituencies gets to be about .973 of normative size with this... I'll probably have to abandon it.

(Oh yes, and: You're right of course.)

[minionofmidas]

The alternative ("Plan 2") would be
1, 2 in Suffolk; 3, 4 in Nassau; 5-7 in Queens; 8-10 in Brooklyn; 11 remnants of Suffolk, Nassau (a very narrow strip), Queens, and part of the Brooklyn remnant; 12 Staten Island and remainder of Brooklyn remnant; 13, 14 in Manhattan; 15, 16 in the Bronx; 17 in Westchester Co; 18 remnants of Manhattan, the Bronx (a very narrow strip) and Westchester, plus not Rockland but Putnam.

Firstly, just spelling this out in trad format:

New York
1 & 2 46% of Suffolk (missing portion, probably in southwest)
ca.657,696 1.005
3 & 4 49% of Nassau (missing portion, probably in Long Beach)
ca.657,695 1.005
5-7 30% of Queens (missing portion, probably includes Rockaway)
ca.657,695 1.005
8-10 27% of Brooklyn (missing portion, probably in south)
ca.657,696 1.005
11 remainder of Suffolk, Nassau, and Queens; 11% of Brooklyn
ca.657,695 1.005
12 Staten Island, remaining 9% of Brooklyn
ca.657,696 1.005
notice the additional county split
13 & 14 42% of Manhattan
ca.648,175 .991
15 & 16 49% of the Bronx
ca.648,175 .991
17 70% of Westchester
ca.648,175 .991
18 remainder of Manhattan, the Bronx, Westchester; Putnam
ca.648,174 .991

Secondly, I'm going to abandon/water down the "proof there's no better alternative" rule.
Here's the reason - two plans for upstate NY. The first is what I came up with initially (well, the first one I found acceptable). The second is what I found when trying to find out whether it could be done better, with changes in red.

So much more hideous to look at, such a tiny improvement in population balance...

I've decided that Suffolk is adjacent to Westchester

In what Bizzaro reality is this happening?  Suffolk is in no way adjacent to Westchester, even if you account for water boundries.

Somehow, a district even more ugly than my current 18th .  Perhaps even uglier than my State Senate district, which even includes Riker's Island to boost its population :-/

What else do your state senator and Charlie Rangel have in common?

[minionofmidas]

I'm redistricting again... based on these rules now:
"Section 26, Article III, of the Texas Constitution requires that house districts be apportioned among the counties according to the federal census population and the following rules:

This looks like something that I originally wrote.  The procedure in Texas is based on the Texas Constitution and judicial interpretations since then.

It's not. Unless you write for theLegislative Council website. (Link provided by Sam, btw.)

You must be logged in to read this quote.

The US Supreme Court has generally permitted a 10% total deviation for legislative[/u] districts[/u].  A range from 104% to 94% is just as legitimate as 105% to 95%. [/quote]Ah, thanks. They've been much more restrictive regarding Congress...

You must be logged in to read this quote.

This is no more likely to pass USSC muster than a 10% range.
[/quote]You're right, I fear... using 1% would sort of defeat the purpose of the exercise though, as additional county splits would have to be done just about everywhere.

So basically I'm going with 2.5% as the limit now, while still attempting to get to 1%.

[minionofmidas]

New Jersey
With just one county under 100,000 inhabitants, just 6 under 200,000, and only 3 over one constituency in size, 5 additional county splits is the best I could do... :/ (Could be dramatically fewer on a 5% variation, I think...)

Pennsylvania
One or two very odd groupings, three additional county splits but it looks like two (Chester County gets split three ways - that's two additional splits, not one), 4-5 districts outside the one percent range, one of which could only be helped by massive changes and perhaps not even then while the other 3-4 are just barely outside.

Could probably be improved on in a number of small ways, but will do for now. One additional county split, which is impossible to avoid. (Montgomery alone = too small. Montgomery + either Darke or Preble = too small. Montgomery + any of the other 5 neighboring counties = too large. Montgomery + Darke + Preble = too large. Montgomery + Darke + any of the 3  additional counties bordering Darke = too large.) There is no alternative to the Summit-Cuyahoga link.

Milwaukee can't be paired with Waukesha, and Waukesha can't be paired with Kenosha and Racine, which kind of limits options. (Waukesha can be paired with Kenosha without Racine, and Racine can be paired with Milwaukee, but while legal, the outer Milwaukee district would look exceedingly ugly.)

Two additional county splits in the southern part of the state (Indian River and Palm Beach) that I really don't see how to avoid, although proving this is long and cumbersome. (I can prove that at least one additional county split is utterly unavoidable, though.) Or you could do a non-consecutive district made up of Saint Lucie, Highlands, and part of Broward. That would avoid any county splits.

Virginia
With recourse to the rules in the initial post, I'm treating the city of Fairfax as part of Fairfax County (in order to not be forced to put it into D1. I could argue that Arlington, Alexandria and Falls Church are also in Fairfax County, and therefore there's no additional county split involved, but that wouldn't, like, actually change the map).
I'm ready to admit the Virginia Beach - North East Virginia district is weird, but the alternative is worse.

Michigan

Nobody claims Missaukee, and two claim Ogemaw and Roscommon.

fixed. Ogemaw and Roscommon with D2, Missaukee with D1. Also found that population given for D2, and the sum of all Michigan districts, was too low by 200 persons.

I'm going down into Georgia to knock down my last game...

Cobb County can't stand alone nor be paired with any neighbor. That I've actually split the offending county rather than a less central one around it is novel, I'll admit.
Populations can probably be balanced better, and I invite anyone to do it. With Georgia's approximately seven million counties, any such redistricting project quickly turns into mechanical calculator-pumping...

Mississippi
I did something novel here... instead of starting from scratch, I just got the current districts in line with the rules. Didn't take much.

D1 gains remainder of Webster Co, loses portion of Winston Co
711,776 1.001
D2 gains remainder of Hinds Co, all of Franklin Co, loses portions of Leake and Madison Cos
712,452 1.002
D3 reverse of all changes mentioned at other districts
708,220 .996
D4 gains remainder of Jones and Marion Cos, loses portion of Jasper Co
712,210 1.001
