Basically Boston Shudra's method is a bunch of BS and easily manipulated by whichever zipcode you pick, especially in cities with large bodies of water.

I'm still laughing that he is here arguing with a straight face that Seattle has about the same 50 sq mi urban mass as Milwaukee.

Water is also a problem for Chicago, Boston, and Providence if the tool doesn't account for it. I hoped that the tool did account for it. If not, then I can only rely on people who know the area enough to move the center away from barren area.

But ultimately, I think "4 miles in a straight line" from the center is a pretty good metric point, even with un-populated water a part of the calculation!

Then pick a center with less water?! If you centered the 4mi radius in Bellevue, would the population be larger?

Nice and yes (I'm not too surprised. LA is a beast). Good find!

It seemed more central! Downtown LA seems to disappear as you go north. Compton seemed to have development in every direction out from it.

But you're absolutely welcome to update my ranking with data about the 4mi radius circle from DTLA.

I found a different zip code - 98103 - that added nearly 100K to Seattle and bumped it to number 8. But I agree it's still not a good representation with the water issue.

So many cities face some sort of "water issue" when being judged by "50 square miles around x point".

That poster used that flawed method that included questionable and arbitrarily chosen zip codes, to go along with the other flaws that you and others have mentioned with the intention to boost Boston to #3 on the density metric.

Using this tool, here are the following cities ranked by "population within a 4 mile radius of the given zip code" using the "Let CAPS decide based on smallest radius" feature.

1) NYC (pop 1,997,622 & zip 11211)
2) Chicago (pop 831,738 & zip 60612)
3) Boston (pop 713,858 & zip 02116)
4) Philadelphia (pop 680,939 & zip 19123)
5) San Francisco (pop 658,482 & zip 94102)
6) Washington, DC (pop 551,330 & zip 20005)
7) Los Angeles (pop 542,383 & zip 90221)
8) Baltimore (pop 405,989 & zip 21201)
9) Miami (pop 396,418 & zip 33128)
10) Minneapolis (pop 348,762 & zip 55402)

---

11) Denver (pop 335,403 & zip 80202)
12) Providence (pop 325,689 & zip 02903)
13) Seattle (pop 323,598 & zip 98101)
14) Milwaukee (pop 322,034 & zip 53201)
15) San Diego (pop 310,506 & zip 92101)
16) Houston (pop 2179,138 & zip 77002)
17) Austin (pop 254,770 & zip 78701)
18) Dallas (pop 249,322 & zip 75202)
19) Atlanta (pop 249,321 & zip 30303)
20) Detroit (pop 219,087 & zip 48202)
21) Hartford (pop 215,108 & zip 06103)
22) Charlotte (pop 161,708 & zip 28202)
23) Nashville (pop 156,562 & zip 37203)

For a lot of the cities, I looked with my untrained eye at the Google Maps satellite view and decided "this looks about right" to determine the center zip code. If you find a higher value for a different zip code for a listed city or you want to add a city to the list using the same tool and the same parameters (4mi radius & let CAPS decide), then feel free to update my ranking with the new numbers.

Know that I will fact check you, though.

If you start from a radius that makes sense in Los Angeles like 90005 (Koreatown), you get 960,000 which puts L.A. behind NYC (where it belongs) with Chicago a pretty distant third. If someone doesn’t think that is fair, we still get over 900,000 from 90017 (DTLA).

Before even opening this thread I assumed Boston would be top 6 easily. Three is hardly boosting..density is what Boston does

I'm not surprised. Sometimes LA can be depicted as the second 2nd most dense large city from a purely statistical standpoint. Its just that LA is not that dense in a traditional urban sense leading (due to LA autocentric and architectural attributes for example) to the overwhelming well reasonably supported subjective views of LA's lack of urbanity.

3) Chicago (pop 831,738 & zip 60612)
