Characteristics of most populous midwest counties

This is a list of the ten most populated midwest counties, with the most populous city that lies within each county, and that city's percentage of the county's total population. All data is from 2006:

1. Cook, IL 5,288,655; Chicago- 2,833,321 (54%)
2. Wayne, MI 2,972,853; Detroit- 918,849 (31%)
3. Cuyahoga, OH 1,314,241; Cleveland- 396,910 (33%)
4. Oakland, MI 1,214,255; Troy- 81,168 (7%)
5. Hennepin, MN 1,122,093; Minneapolis- 369,051 (33%)
6. Franklin, OH 1,095,662; Columbus- 733,203 (67%)
7. St Louis, MO 1,000,510; Florissant- 49,325 (5%)
8. DuPage, IL 932,670; Naperville- 147,779 (16%)
9. Milwaukee, WI 915,097; Milwaukee- 602,782 (66%)
10. Marion, IN 865,504; Indianapolis- 785,597 (91%)

It's easy to distinguish the strictly-suburban counties, which contain no dominant city. Oakland is suburban Detroit, DuPage is suburban Chicago, and St Louis contains suburbs of the City of St Louis, (an independent city.)

Conversely, note how Indianapolis (372 square miles) dominates Marion County (403 square miles) with 91% of the county's population.

Troy is a 34 sq. mi. mid-ring suburb of Detroit. It is mostly made up of newer subdivisions and office parks. It is the "office center" of Oakland County, but it isn't the "main" city. Pontiac is the original "major" city of Oakland County, while the Royal Oak area represents the population "center". Pontiac has a little under 70,000 people in about 20 sq. mi., but the Royal Oak area (which actually includes 10 different cities) has a population of over 200,000 in about 38 sq. mi. Troy currently is the largest it has ever been, Pontiac peaked in 1970 with over 85,000 people, and the Royal Oak area peaked in the late 60's with nearly 280,000 people, again in just 38 sq. mi.

This is due to Unigov.
what would the percentage be if the city of St Louis was merged into the county?

The list would then look like this:

2. Wayne, MI 2,972,853; Detroit- 918,849 (31%)
3. St Louis, MO 1,354,347; St Louis- 353,837 (35%)
4. Cuyahoga, OH 1,314,241; Cleveland- 396,910 (33%)
5. Oakland, MI 1,214,255; Troy- 81,168 (7%)
6. Hennepin, MN 1,122,093; Minneapolis- 369,051 (33%)
7. Franklin, OH 1,095,662; Columbus- 733,203 (67%)
8. DuPage, IL 932,670; Naperville- 147,779 (16%)
9. Milwaukee, WI 915,097; Milwaukee- 602,782 (66%)
10. Marion, IN 865,504; Indianapolis- 785,597 (91%)
I didn't notice the first time, but Wayne County doesn't have nearly 3 million people. It has about 2 million people (with the official "estimate" at 1,971,853). That means that Detroit is about 47% of Wayne County.
BTW, these are the numbers from census.gov. They are the estimates as of July, 2006 and don't include any corrections that the Census Bureau may have made since their initial release.

1. Cook, IL - 5,280,306 - Chicago - 2,833,321 - 54%
2. Wayne, MI - 2,012,376 - Detroit - 871,121 - 43%
3. Cuyahoga, OH - 1,309,262 - Cleveland - 444,313 - 34%
4. Oakland, MI - 1,207,898 - Troy - 81,118 - 7%
5. Hennepin, MN - 1,128,798 - Minneapolis - 372,833 - 33%
6. Franklin, OH - 1,109,867 - Columbus - 733,203 - 66%
7. St. Louis, MO (city+county) - 1,345,885 - St. Louis - 347,181 - 26%
8. Milwaukee, WI - 952,315 - Milwaukee - 573,358 - 60%
9. DuPage, IL - 927,757 - Naperville - 142,901 - 15%
10. Marion, IN - 872,986 - Indianapolis - 785,597 - 90%
11. Hamilton, OH - 847,368 - Cincinnati - 332,252 - 39%
12. Macomb, MI - 829,539 - Warren - 134,589 - 16%

You should probably make the corrections yourself, though, to give a more accurate picture. Also, why'd you decide to use the 2006 numbers when the 2007 numbers are available? Was it to keep Wayne above 2 million? lol
Because they don't have data for cities from 2007 yet. If I did use 2007 data, Macomb County would be closer to approaching the top ten. It will probably pass Hamilton County by 2010 and if the estimates are remotely accurate could pass Marion County sometime after. Hamilton supposedly lost nearly 3,000 people between 2000 and 2006, Marion added about 16,400 during that same period, but Macomb added nearly 43,000.
I thought that Marion Co & Indy were totally combined, kind of like a midwestern Miami Dade. I guess I was wrong.
edsg25, there is a consolidated city-county government, but like most consolidations, previously existing municipalities were not absorbed into the new entity. The Census Bureau treats those places as their own independent cities, and only counts the "remainder" population as the core city.
I would think that Dupage County has reached 1,000,000 by now. Giving Chicagoland two couties with 1,000,000 +

Oops, sorry for the typo. I mean to say that Wayne County had 1,972,853 people in 2006.
Think of Indianapolis (balance) as the former city plus all of the formerly unincorporated land within Marion County. There are quite a few "independent" towns that exist within the boundaries of Marion County that are a part of the "uni-gov" but are statistically separate from Indianapolis (balance). They are:

Cumberland (part) - 5,500
Meridian Hills - 1,713
Warren Park - 1,656
Clermont - 1,477
Homecroft - 751
Rocky Ripple - 712
Williams Creek - 413
Wynnedale - 275
Spring Hill - 97
Crows Nest - 96
North Crows - 42

Basically they are able to maintain separate autonomy, but are not able to do anything that is not in accordance with Indianapolis ordinances. In other words they can maintain their own roads, police, schools, etc. if they wish, otherwise those services would be provided by the city-county government.

There are also four cities within Marion County that are autonomous on a local level. They have their own mayors, police forces, school districts, etc. However, they do have the ability to vote for Indianapolis mayor and certain city-council members, as they are still under the authority of the "county" portion of the government. They are:

Lawrence - 38,915
Beech Grove - 14,880
Speedway - 12,881
Southport - 1,852

Pssht... Detroitland did that decades ago...

;)
BTW, on an intersting side-note, if every community in Detroit's Tri-County area had maintained its peak population, it would have had a population of 5.4 million people in 1,967 sq. mi. If you removed the rural outer townships, the "peak population" would have still been 5.1 million in 1,182 sq. mi. In comparison, Cook County had a 2000 population of 5.4 million people in 945 sq. mi.

In reality, the "core communities" only have a population of 3.7 million, with the Tri-County area having a population of 4.0 million.

Here is the breakdown for each individual county:

Wayne - 3,222,718 (what could have been) - 2,061,162 (reality)
Oakland - 1,304,121 - 1,194,156
Macomb - 885,318 - 788,149

DuPage County is not over 1 million - it only has 929,000 and growth has slowed significantly. It may be that DuPage County never reaches one million, though the odds would still favor it I think. Inner ring DuPage County burbs are already showing signs of population decline.

Interesting. Dupage is probably losing tons of would-be home buyers to less expensive Will County or Kendall County.

I believe Jacksonville, Florida and Columbus, Ohio have similar city-county governments.
Columbus does not. It's just that half the damn county is Columbus though there is a regional government commission.
