Compound County Clusters:

Concord doesn't extend the area so is a subset of SFO.

San Francisco--Oakland, CA; Concord, CA(5): Alameda County; Contra Costa County; Marin County; San Francisco County;  and San Mateo County.

LA includes LA, Orange, and SB; so others extend to Riverside and Ventura.

Los Angeles--Long Beach--Anaheim, CA; Riverside--San Bernardino, CA; Oxnard, CA; Thousand Oaks, CA(5): Los Angeles County; Orange County; Riverside County; San Bernardino County;  and Ventura County.

Turlock spans the county line.

Modesto, CA; Merced, CA; Turlock, CA(2): Merced County;  and Stanislaus County.

All but Windham and New London, but I doubt that counties can be used in CT.

Hartford, CT; Bridgeport--Stamford, CT--NY; New Haven, CT; Waterbury, CT; Danbury, CT--NY(6): Fairfield County; Hartford County; Litchfield County; Middlesex County; New Haven County;  and Tolland County.

Smaller UA of Bonita Springs spans the two counties.

Cape Coral, FL; Bonita Springs, FL(2): Collier County;  and Lee County.

6 counties span from Ocala to Kissimmee

Orlando, FL; Kissimmee, FL; Lady Lake--The Villages, FL(6): Lake County; Marion County; Orange County; Osceola County; Seminole County;  and Sumter County.

3 western counties.

Pensacola, FL--AL; Fort Walton Beach--Navarre--Wright, FL(3): Escambia County; Okaloosa County;  and Santa Rosa County.

Same extent as Sarasota-Bradenton

Sarasota--Bradenton, FL; North Port--Port Charlotte, FL(3): Charlotte County; Manatee County;  and Sarasota County.

Stack of 3 on east coast above Palm Beach

Port St. Lucie, FL; Sebastian--Vero Beach South--Florida Ridge, FL(3): Indian River County; Martin County;  and St. Lucie County.

Adds in Hernando to Tampa-St. Pete

Tampa--St. Petersburg, FL; Spring Hill, FL(4): Hernando County; Hillsborough County; Pasco County;  and Pinellas County.

Does not extend Chicago area.  Chicago UA does extend into Grundy.  An argument might be made to exclude it since it is not the largest urban area in the county.

Chicago, IL--IN; Round Lake Beach--McHenry--Grayslake, IL--WI(8): Cook County; DuPage County; Grundy County; Kane County; Kendall County; Lake County; McHenry County;  and Will County.

A quirk since Baltimore Urban Area does not enter Harford, and the census bureau does not merge urbanized areas.  It appears that the Baltimore and Aberdeen UA were deliberately drawn to the county line.  But there was no urbanized area further south to stop Baltimore from overrunning Annapolis and jumping the bridge.

Washington, DC--VA--MD; Baltimore, MD(8): Anne Arundel County; Baltimore County; Frederick County; Howard County; Montgomery County; Prince George's County; Queen Anne's County;  and Baltimore city.

Only Barnstable is added to the Boston area.

Boston, MA--NH--RI; Providence, RI--MA; Barnstable Town, MA(8): Barnstable County; Bristol County; Essex County; Middlesex County; Norfolk County; Plymouth County; Suffolk County;  and Worcester County.

Grand Rapids, MI; Muskegon, MI(3): Kent County; Muskegon County;  and Ottawa County.

Detroit, MI; Ann Arbor, MI; South Lyon--Howell, MI(6): Livingston County; Macomb County; Oakland County; St. Clair County; Washtenaw County;  and Wayne County.

Boston, MA--NH--RI; Nashua, NH--MA; Manchester, NH(3): Hillsborough County; Merrimack County;  and Rockingham County.

Leaves out Cumberland and Cape May.  Trenton (Mercer and Burlington) joins the two larger areas.

New York--Newark, NY--NJ--CT; Philadelphia, PA--NJ--DE--MD; Trenton, NJ(18): Bergen County; Burlington County; Camden County; Essex County; Gloucester County; Hudson County; Hunterdon County; Mercer County; Middlesex County; Monmouth County; Morris County; Ocean County; Passaic County; Salem County; Somerset County; Sussex County; Union County;  and Warren County.

Expends the capital area northward.

Albany--Schenectady, NY; Glens Falls, NY(6): Albany County; Rensselaer County; Saratoga County; Schenectady County; Warren County;  and Washington County.

Charlotte, NC--SC; Concord, NC(6): Cabarrus County; Iredell County; Lincoln County; Mecklenburg County; Rowan County;  and Union County.

Winston-Salem, NC; Greensboro, NC; High Point, NC(5): Davidson County; Forsyth County; Guilford County; Randolph County;  and Stokes County.

Cleveland, OH; Akron, OH(9): Cuyahoga County; Geauga County; Lake County; Lorain County; Medina County; Portage County; Stark County; Summit County;  and Wayne County.

Cincinnati, OH--KY--IN; Dayton, OH; Middletown, OH(8): Butler County; Clark County; Clermont County; Greene County; Hamilton County; Miami County; Montgomery County;  and Warren County.

This one kind of gets out of hand.

Harrisburg, PA; Hanover, PA(5): Adams County; Cumberland County; Dauphin County; Lebanon County;  and York County.

Extends Pittsburh down the Monongahela.

Pittsburgh, PA; Monessen--California, PA(6): Allegheny County; Beaver County; Butler County; Fayette County; Washington County;  and Westmoreland County.

SEPa picks up Lehigh Valley and Reading.

Allentown, PA--NJ; Philadelphia, PA--NJ--DE--MD; Allentown, PA--NJ; Reading, PA; Pottstown, PA(9): Berks County; Bucks County; Carbon County; Chester County; Delaware County; Lehigh County; Montgomery County; Northampton County;  and Philadelphia County.

No change.

Dallas--Fort Worth--Arlington, TX; Denton--Lewisville, TX(7): Collin County; Dallas County; Denton County; Ellis County; Johnson County; Rockwall County;  and Tarrant County.

This is a quirk of the census delineation.  Port Arthur UA includes the cities in between Beaumont and Port Arthur (Nederland, Port Neches, Groves, and then continues up the Sabine to Orange).  Beaumont UA includes Beamont and Vidor in Orange and extends north into Hardin County.  Port Arthur UA is the larger UA in both Jefferson and Orange counties, making those two the "central counties" of a metropolitan area, while Beaumont UA is the largest in Hardin, making it the central county of a different metropolitan area, but it is then converted to an outlying county.   Bur the name of the MSA is based on the name of the largest city, Beaumont.

If Beaumont UA were to become the largest in Jefferson County, and they are close, 117K vs 113K, Jefferson and Hardin counties would become central counties, as would Orange County based on Port Arthur UA.  Orange would likely become an outlying county.

Port Arthur, TX; Beaumont, TX(3): Hardin County; Jefferson County;  and Orange County.

Fredericksburg extends the area out a bit.

Washington, DC--VA--MD; Fredericksburg, VA(13): Arlington County; Fairfax County; Fauquier County; Loudoun County; Prince William County; Spotsylvania County; Stafford County; Alexandria city; Fairfax city; Falls Church city; Fredericksburg city; Manassas city;  and Manassas Park city.

The two cities share Putnam County.

Huntington, WV--KY--OH; Charleston, WV(4): Cabell County; Kanawha County; Putnam County;  and Wayne County.

I follow your logic clearly here, but part of it seems to be personal taste with respect to metro areas. Based on real public testimony in IL in 2011 your view is consistent with some, but not the majority of that testimony. For example many residents of Grundy county, IL would be happiest to see themselves not forced into the same region as Chicago. However, commuting patterns actually do matter a lot for some of the public when it comes to a CoI, and that forms the basis of the existing rules for merging (and I did find such rules for the merger of CBSAs even if there was a clear policy decision to resist merging UAs between 2000 and 2010).

UAs are delineated based on continuous high density residential population.   It is difficult if not impossible to determine where one starts and another ends, or if they are actually separate.  It is like trying to determine where Europe ends and Asia starts, or whether North and South America are separate continents.

In 2000, the census bureau switched to defining urban areas based solely on population density, without regard to political boundaries.  Previously, urbanized areas had been defined based on larger cities to which adjacent territory was added.  The urban areas based on actual settlement patterns spanned larger areas.  But the census bureau wanted to maintain previous urbanized areas (or perhaps had political pressure, since an urbanized area meant that its county was a metropolitan area).

So if an initial urban area in 2000 of more than 50,000 crossed an (1990) MSA boundary, it was split.  If the distance of contiguity was 3 miles or less, it was split near the MSA border, presumably at an isthmus.  If the distance of contiguity was 3 miles or more, it was split on the MSA border.  If there were two or more initial urban areas of more than 50,000 within a MSA or a county outside a metropolitan area, they could be separated if they were connected by a hop or a jump, or point connected.

In 1990, when MSA were merged based on commuting, the merged areas became PMSA, and the merged area a CMSA.   At the time the 2000 urbanized areas were delineated, Washtenaw, Livingston, and Lenawee formed a PMSA; as did Oakland, Macomb, Wayne, St.Clair, Lapeer, and Monroe; Genesee was also a PMSA; and the 3 CMSA formed a PMSA.

So when the 2000 urban areas were delineated, urbanized areas were chopped near the Washtenaw and Livingston county boundaries.  So you have continuous dense residential settlement but separately delineated urbanized areas.  Port Huron, Monroe, and Toledo urbanized areas are physically separated from Detroit, so even if they could be connected by jumps and hops, were kept as independent urbanized areas.

In 2010, the census bureau had a rule against merging urbanized areas.  They do permit merging of urban clusters.

So even though they recognize continuous residential settlement, they make a somewhat arbitrary division, which in turn prevents recognition of the groups of counties that actually contain the continuous residential settlement.

While you suggest that the census bureau is authoritative, they don't warranty the use of their definitions for other purposes than gathering statistical information.

To be able to compare plans they must have the same number of regions.

We could have a set of rules that:

1) exclude both Genesee and Washtenaw from the Detroit region;
2) exclude Genesee;
3) exclude Washtenaw; or
4) include both Genesee and Washtenaw.

I would oppose Rule 2 because it would be factoring in economics (ie auto industry v university)

Rule 1 could be:

County in CSA plus substantial portion of population in Urbanized Areas (eg 33%+)

Wayne 99%
Macomb 96%
Oakland 94%
Genesee 83%
Washtenaw 80%
Livingston 61%
St.Clair 61%
Monroe 59%
=========
Lapeer 0.1%
Lenawee 0%

Kent 82%
Ottawa 79%
Muskegon 71%
============
Allegan 9%

Kalamazoo 82%
Calhoun 57%
===========
Van Buren 6%

Ingham 85%
Eaton 45%
Clinton 36%

Bay 70%
Saginaw 66%
Midland 57%

Benton 57%
========
Cass 17%

Definition should also include MSA not in CSA (Jackson is the only such MSA in Michigan).

Jackson 56%

Rule 2 would be formulated like I have.  It is possible that the threshold could be raised for amount of significant cross-border crossing.

Rule 3, I don't know to formulate a rule that would include Flint, but exclude Washtenaw.

Rule 4, would be MSA only with significant urban population.  Compared to Rule 2 this would split off Genesee, Washtenaw and Monroe, to create 5-county Detroit urban county cluster.  Muskegon would be split off from Kent and Ottawa.  Would split Kalamazoo and Calhoun; and Saginaw, Bay, and Midland.

Edit: Numerous corrections to maps.

This is a maximalist definition of urban consolidate clusters.  Each county in a cluster is a member of a consolidated statistical area, and has 25% or more of its population in urbanized areas.  That is there is functional integration through commuting patterns that join counties into CBSA (mostly metropolitan statistical areas (MSA)), and have a relatively large share of their population in urbanized areas (areas of continuous high density settlement of 50,000 or more).  This avoids the problem of cases where urbanized areas were truncated near a county line, which caused the counties to be placed into different central county clusters, which in turn became outlying counties or separate metropolitan statistical areas.



In Virginia, Harrisonburg, Staunton, and Waynesboro independent cities were treated as if they were still part of Augusta and Rockingham counties for creation of the Harrisonburg-Staunton-Waynesboro CSA.  Otherwise both the remaining counties failed the 25% test.  In the case of other independent cities in Virginia this adjustment was not needed.  It the population had grown large enough to be an urbanized area (50,000) it likely has outgrown the independent city boundaries to also contain a large share of the surrounding county population, or the independent cities have been expanded to encompass a whole county (e.g Chesapeake and Virginia Beach).  Pittsylvania County (Danville), Albermarle (Charlottesville), Washington (Bristol), and Frederick (Winchester) the surrounding counties do meet the 25% threshold.

Montgomery (Radford) also qualifies, but this is as part of the Blacksburg UA (Blacksburg is not an IC).  None of Radford appears to have been taken from Pulaski County, and Blacksburg UA only extends a small bit into Pulaski County.

There are two disjoint parts of the urban county cluster associated with Washington-Baltimore-Arlington, DC-MD-VA-WV-PA CSA.  Frederick (Winchester) are part of the Winchester MSA which has its core as the Winchester Urbanized Area.  Counties to the east such as Clarke and Warren are outlying counties of Washington-Arlington-Alexandria, DC-VA-MD-WV MSA but the Washington urbanized area does not stretch that far (Loudoun is a central county of the Washington MSA).   The pattern extends across the border into West Virginia, Maryland, and Pennsylvania where portions of the Hagerstown and Chambersburg MSA are included in the Washington-Baltimore-Arlington CSA, while Jefferson County, WV is directly in the Washington MSA, but not urbanized.

The Kansas portion of the cluster based on the Kansas City-Overland Park-Kansas City, MO-KS CSA is in two parts, with Doniphan County qualifying as part of the St.Joseph MSA.



Hamblen County, Tennessee is a disjoint portion of the cluster based on the Knoxville-Morristown-Sevierville, TN CSA, but is in the Morristown MSA based on the Morristown UA, which at 59,000 persons barely qualifies as an urbanized area, as opposted to an urban cluster.

This is a minimalist version.  Counties in a urban county cluster share a metropolitan statistical area and 25% or more of their population in an urbanized area.  The commuting standard for inclusion of a MSA in a CSA is less than for including an outlying county in an MSA, so a CSA may represent a weaker link.  The 25% threshold eliminates counties removed from the core that are only linked by commuting ties.

CSA are named based on their largest cities, which is not always that of their largest MSA.  In the following tables, the main MSA of a CSA is considered to be the one with the largest population.  Thus the San Francisco-Oakland MSA is considered to be the main MSA of the San Jose-San Francisco-Oakland CSA, and thus the San Jose MSA is treated as secondary.  Similar situations occur in Johnson City-Kingsport-Bristol, where the Kingsport-Bristol-Bristol MSA is larger than Johnson City MSA, and Charleston-Huntington, where Huntington-Ashland MSA is more populous than Charleston.

My fair LA:



Bringing CD2 into Lafayette makes CD6 more compact and competitive. Romney actually performed worse than McCain, winning it 56/42 instead of 58/41.

CD4 would be better for Republicans, at 60/38 Romney.

CD3 is more of a fair fight, at least on the R side. It splites 55/45 in favor of Boustany instead of 75/25, as with the actual map.
