F*ck the CMA: Find Population on Map

I get 10,425,440 for Philadelphia.

New York State boundaries are drawn especially poor, but the state borders around Baltimore and Philadelphia are not *that* skewed when Baltimore is fairly centrally located in Maryland, or that Southern New Jersey should overwhelm Pittsburgh and rural Pennsylvania.

population overlap with New York, Wilmington and Baltimore.
a radius of 62 miles = 12,130 square miles. that's a larger area than 9 states
NYC = 301 square miles = 8,336,817
LA = 468 square miles = 3,979,576
Chicago = 227 square miles = 2,693,976
Philadelphia = 134 square miles = 1,584,064

I think you're right. I was looking around the website 2-3 days ago and couldn't figure out how to find out where they got their information or from what year(s)

I used the polygon option to follow the exact boundaries of the City of Toronto.

It showed a population of less than 2.5M

The last time the City of Toronto had a census population under 2.5M was 2001.

To further check; I followed the boundaries of Brampton, a large Toronto suburb.

It shows a population of 373,000; the most recent census (2016) shows 593,000

This also appears to be 2001 data.

Using the 62.14 mile/100 km parameter;

New Delhi, India: 40,092,790

Lagos, Nigeria: 12,643,320 (Half of the circle is in water)

San Francisco: 9,148,084 (If I place the circle center on Tracy, CA)

Moscow: 17,965,100

London: 18,285,010

NYC: 20,598,460

Paris: 13,120,800

Mumbai: 23,567,500

Shenzhen China: 35,789,020 (Hong Kong is in the coverage)

Jacksonville, FL: 1,569,841 ()

[kool maudit]

Stockholm: 2,382,224.

Seems about right. But let's get into metropolitan Europe, the big old railway groupings:

Amsterdam: 11,355,800
Cologne: 16,834,440
Brussels: 12,979,540

Liège: 10,577,850!

And neither metro has a major body of water or undeveloped zone messing up the numbers.

Southeast England is otherwise more densely settled than Northern France - a 100km radius around London is picking up more towns orbiting the metro. And in either case it's projecting much further than their traditional (similarly sized) metro areas.

Although if you were to extend it by an extra 20km, Paris would pick up another 2 million people as that would then include some not-so-insignificant cities like Rouen, Orleans, and Amiens that are just over 100km from the city centre.

[BigDipper 80]

There are 4,606,091 people within 100 km of Xenia, Ohio (population 27,000).

Here are the Ohio 3C Cities:

Cincinnati: 3,332,118

Columbus: 2,703,420

Cleveland: 4,175,302

Houston: 5,156,490
Miami: 4,965,401
Cleveland: 4,105,153
Seattle: 4,025,621

This might surprise some.

For Miami about 90% of the circle is the Everglades or the Ocean. As you can see with Miami, it is not the geographic center of its CSA, Fort Lauderdale is. The tool struggles with metros that are not circles.

So London is more similar to Los Angeles in that fashion and Paris is more related to New York

I looked for some small metros to spot check. Boise was strange, looked at Reno and Las Vegas with a 20 mile radius and the population is very close to the 2000 census count. I don't know if every return is from 2000 census, or if some returns from other cities and countries are using more recent info.

I don't think that's an accurate comparison at all. New York has many more people living in its hinterlands than Los Angeles. Once you get out of the LA urbanized area (meaning LA, IE, OC, portions of Ventura County) there is almost nothing. Open desert and mountains to the east and north, Pacific to the west. You do have San Diego to the south, but in New York's case, you have countless small towns and cities in Jersey, Connecticut, NE Pennsylvania. It basically bleeds into Philly, which bleeds into Baltimore, which is basically intertwined with Washington. The East Coast much more closely resembles the regional population density of SE England than LA and SoCal.

London isn't similar to NY in that regard at all. Mostly everything within a 100km radius of Manhattan is part of the NY MSA. And, almost nothing within 100km radius of Manhattan is not in the NY CSA (only the parts that overlap with the Philly MSA/CSA).

Huh? I was saying that the NE corridor is more analogous to SE England than Southern California. It has nothing to do with what is and isn't counted in an MSA or CSA. There are lots of little towns and lightly populated areas in the Northeast, while in SoCal you're either part of the contiguous LA/IE urban area, or it's essentially uninhabited.

--- Many super dense rural areas are excluded with the 75km radius. Still, Asian regions are impressive;

--- US metro areas fell a lot without their exurbs. Chicago goes below 10 million. The distance between Chicago and NY/LA are much smaller then CSA numbers show.

Dhaka is the 1st in both measures.

I got New Delhi - 40,837,150

I wonder what point on this planet will yield the highest population?
