In 143 sq miles
Philly City Center - Google Maps
Dallas Downtown Dallas - Google Maps, Uptown - Google Maps

In 385 sq miles
Philly City Center - Google Maps
Dallas Downtown Dallas - Google Maps, Uptown - Google Maps, Dallas Galleria area - Google Maps, North Central Expressway - Google Maps

To centralize the industrial, commercial, commerce and employment centers I can understand Dallas city size. “some cities don’t put all there eggs in one basket” metaphorically Dallas have to have a larger area to cover all it’s (eggs) CBD’s that being said Dallas is going to be less dense. Philly on the other hand has all it’s eggs in one basket if Philly was the size of Dallas it would over annex, gain nothing more than dense suburbs. Posters seem to care more about the density of neighborhoods than there actual functions.

First NYC, which, clearly, is going to outperform any other city, when it comes to density concentration, by far:

Is there a best way to determine comparative city population-nyc.jpg



The top 3 zips, pop per sq mile 2007:
10128: 145460 per sq mile
10028: 140054.3
11109: (Long Island City) 121400

It takes a study such as this to illustrate how far ahead the NYC area is, even to Boston, which previously appeared to be the most dense MSA. The NYC area has 183 zip codes that have over 10,000 people per square mile. This includes several zip codes in Northern New Jersey.

In comparison, some of the other cities most densely populated zip codes:
Kansas City: 9331.9
St. Louis: 9465
Denver: 17385
Charlotte: 5771.4
Raleigh: 5537.9
Houston: 17697.7
Boston: 57940

New York City's (and surrounding area) disparity with other cities is even more pronounced than I would have previously considered.

Atlanta, using 10k as the highest classification, like most other cities, sans NYC and Boston:
Is there a best way to determine comparative city population-atlanta.jpg

Top 3 most dense zips in 2007:
30313: 9034.7 per sq mile
30308: 8602.9
30312: 7032.7

Chicago:

Top 3 zips in 2007 per sq mile
60660: 37358.1 per sq mile
60626: 33550.3
60611: 33382.1

Chicago has 46 zip codes with over 10k per sq mile population density.

Mike can you do me a favor and do Houston, Dallas, Atlanta, Philly, Boston, and DC, and put them on the same scale and density.

This capture what I’m taking about how cities are built different, Boston core is denser than Atlanta but Atlanta sprawl more, but the legends are off so the comparison is off. I’m trying show why sunbelt cities have larger MSAs.

Unbelivably, these two posted maps of Boston and Atlanta are at the same exact scale (1:622000). That's pretty incredible to consider, and it also magnifies how small New England is, scale-wise, compared to the rest of the country. In fact, every map I made is at 1:622000, with the exception of the second Boston map, and the Miami map, which was at 1:585000, slightly smaller, but done in portrait instead of landscape, to depict the unique vertical nature of population dispersion there.

The density classification was different for NY and Boston, because they are much more unique in settlement than the rest of the country. That said, I'll make one overall post, and have the entire setting at 1:622000, and, with 10k being the highest break on density. Is that agreeable, or did you want something different?

Mike we are killing you, but i think this is in a different density distribution

It is. I can adjust Philly to 10k, or make all the others 5k as well. I think you guys need to get consensus, then I'll do a one-off project. Since the files are all saved, it won't take that long to make them all one density classification.
