How many people live within a 50 mile radius of your city?

That was the reason, great game and great time.

uh, wouldn't that be true for LA and SF too?

Anything more than 50 miles or so (I would say less, even) is beyond the distance of commutability and isn't really contribute anything to a city.

Philadelphia is probably the one exception here, as it's 50mi radius no doubt bleeds into NYC's NJ suburbs. Still, it does reflect it's potential commuter shed and media market to draw upon though.

LA's metro population doesn't really stretch to Arizona, that's nuts. I'd guess 90% of the Inland Empire population 40-90 miles from downtown LA or so.

It's cool, but the approximations are much better along the east coast than elsewhere because of the smaller land areas of the counties in that region. For instance, Detroit and Woodhaven, MI have the same radius population count but they should not. Woodhaven should pick up Toledo in the 50 mile radius and drop some of the areas in Detroit's northern suburbs. I assume the count doesn't change for Woodhaven because it is in the same county as Detroit, because if I choose Southfield, MI - which actually borders Detroit - the 50 mile radius population count jumps up by almost 700K.

Another example is Newark, NJ and Elizabeth, NJ. Like Detroit and Southfield, they border each other but are in different counties. The count of population in the 50 mile radius differs by almost 1M.

Agreed - When looking at San Diego (a county the size of Connecticut), the 25 mile and 50 mile radii populations are identical (3.3 million). Switch to 75 miles, and it suddenly grabs two very large counties, incorporating the entirety of their populations (8.9 million)

I think when people think "LA" they think all of Southern CA sans San Diego.

[mousquet]

50 miles!? Hè, that's a long ride on a daily basis, people... Like 80km.

Frankly, I have no idea. It must be in the 12+ million.
Not counting illegals. Bwahaha!

I was born there. I visit family about once a year. It's become a lot fancier in the 45 years since I was born. When I was born, there were riots in the old Idaho State Penitentiary, which my parents' home was directly adjacent to. I don't think the two events were related, though.

And NYC and just about any City worth visiting ... :-D

For Shanghai, a 50 mile radius would include the cities of Kunshan, Suzhou, and Jiaxing, so probably 35+ million people.

For Tokyo, a circle with a 50 mile radius centered on the Imperial Palace ends to the north a little south of Nikko, in the middle of Kofu City to the west, a few miles out to sea off Yokosuka to the south, and a few miles short of the Chiba beaches to the east. So not the entire Kanto Plain, but close to it.

That's about 37 million people. The northern burbs of the Tokyo metropolis in southern Tochigi and Gunma get left out.

Anyhow it's interesting how this differs from MSA rankings:

50-mile radius population:
New York 20,812,722
Los Angeles14,208,130
Chicago 9,380,730
Philadelphia 8,666,832
San Francisco 7,756,158
Boston 7,355,243
Dallas 7,132,900
Washington DC 6,910,078
Houston 6,892,427
Atlanta 6,024,185
Phoenix 4,737,270
Miami 4,687,674
Detroit 4,670,928
Seattle 4,592,151
Tampa 4,190,864
Minneapolis 3,722,902
Cleveland 3,526,126
Denver 3,515,374
San Diego 3,337,685
Portland 2,901,364
St. Louis 2,857,604

One thing I notice immediately is that the population in SW Ontario is missing from Detroit's numbers. Despite being in a different country, they still have as strong socio-economic linkage to the city.

When they're accounted for, Detroit's true populqtion is much bigger than 4.6 million.

For Toronto it would be somewhere between 8-9 million. A 50 mile radius from downtown Toronto would take in Guelph and parts of Waterloo Region in the West, all of Metro Hamilton and most of Niagara Region, as well as Buffalo's Northern suburbs. It would reach the South end of Barrie/Simcoe County in the North and go past Cobourg in the East.

This is also true of San Diego, but it would be interesting to compare how Tijuana and Windsor differ in their integration with the respective border cities.

Doesn’t this just sum up county populations?

50 miles radius is is 7800 square miles

LA + riverside urban areas are much smaller in area (around 2400 square miles) with 15.6 million if I remember correctly

[Centropolis]

south dingleberry makes another .64 millon tho

[AviationGuy]

Austin 2,332,449 for 50 miles.

5,849,125 for 100 miles

21,364,786 for 200 miles (pulls in Houston, DFW, San Antonio, Corpus Christi)

Yeah it sums up counties. Pretty lame IMO. Using census blocks would be much better (but perhaps too computationally intensive to be deployed wantonly as a service). Sounds like a fun project though... if I get a few spare cycles before I forget about it it'd be fun to make a tool to do this.
