That poster is only able to copy/paste some silly stat that is pretty much meaningless, he will not be able to comprehend any actual meaning behind the data.

Philly has 4.5M people in a 20 mile radius from City Hall; a 20 mile radius is 1,256 sq miles (Pi x r2), so essentilly what you are saying is Philly has 4.5M people in 1,256 sq miles.
Chicago has 2.7 million people in 227 sq miles and 5,200,000 in 946 sq miles (cook county).

So no, Philly is not larger than Chicago. Seriously, how do you not understand simple math?
agree

Philly actually holds up pretty well out to about 200-250 sq miles, something like 2.4 based on some calculations I did. Where the distance grows is the next 500-1000-1500 sq miles (philly gets to about 4.5 million in like 850 sq miles but isnt radial, the population is more linear SE to NE with a larger concentration radius in the middle, the combined UA is 5.6 million in like 1400 sq miles I believe where the concentration starts to fall off less extending more linerally along the NE corrider but again into NYC territory or so says the census). going larger there are more people in a range of Philly but that is when you start adding in NYC areas and getting pretty damn far from the core.


Chicago is the bigger area though no doubt

Thank you. I did a calculation once with Philly at 227 sq mi (the size of Chicago) and it cam out to ~2.2M people.

that makes sense. I think I did ~250 at 2.4 - sounds about right give or take

I also did a count to 200 on connected zips, was like 2.05 so again the 2.2 sounds right to me based on what I have seen at a comparable 227. At that size I believe Philly would be 4th behine NYC/LA/Chicago with SF right on the heals at 227 as I think SF was at like 1.85 or so at 200 when I did a comparison.

It's interesting in how that number is close to what Philly's peak population was back in 1950. Of course it's still smaller than Chicago's peak population of 3.6 million.

Right, Philly was definitely 4th, about 200K ahead of San Fran, followed by Boston.
