In terms of the "big six" urban cities in the US, I also thought it would be interesting to look at the 1950 census. Essentially this was taken at the very beginning of the postwar era when many major American cities were at their peak population and built urbanism. I decided to just get the top 19 cities only.
1950 Census
1 New York 7.8 million
2 Chicago 3.6 million
3 Philadelphia 2 million
4 Los Angeles 1.9 million
5 Detroit 1.8 million
6 Baltimore 950 thousand
7 Cleveland 915 thousand
8 St. Louis 857 thousand
9 Washington 802 thousand
10 Boston 801 thousand
11 San Francisco 775 thousand
12 Pittsburgh 677 thousand
13 Milwaukee 637 thousand
14 Houston 596 thousand
15 Buffalo 580 thousand
16 New Orleans 570 thousand
17 Minneapolis 522 thousand
18 Cincinnati 504 thousand
19 Seattle 468 thousand
Based on this list, many of the actual big six are on top, but it's still interesting to see that LA was in the top 5 even back then, overtaking Detroit during the 1940s. But, damn, if only Detroit, Cleveland, and other Rust Belt cities had surpassed their peak populations.

L.A. had a large population in 1950, but it was much less dense than the other big cities:

- Valley minus Burbank, Calabasas, Glendale, Hidden Hills, and San Fernando: 1,473,236 in an area of 194 sq. miles for a density of 7,577 ppsm.
- Los Angeles minus Valley population: 2,425,511 in an area of 275 sq. miles for a density of 8,802
So removing the Valley just slightly increases L.A.'s 2020 density from 8,312 ppsm to 8,802 ppsm.
Prewar L.A. also did not really match the big eastern cities in terms of scale of density. Los Angeles's 1950 population was 1.9 million and roughly 200k-300k of the population was in the San Fernando Valley by then. Los Angeles would have still easily been in the top 5 by population without the Valley, but its population density would've still been far lower than the rest of the top 5 in 1950:
U.S. cities with greater than 1 million in 1950 by population density (in people per square mile)- New York - 26,306.52
- Chicago - 15,951.37
- Philadelphia - 15,459.74
- Detroit - 13,402.67
- Los Angeles - 4,201.18 (w/o Valley between 6,074 ppsm and 6,437 ppsm)
