The biggest North American cities without MLB: 1920/1930

 

I'm mostly putting this here as a resource for myself. 

Compiling the 1920 US Census, 1921 Canadian Census, Mexican data from 1921, the 1919 Cuban Census, and the 1920 Santo Domingo Census, the largest cities without MLB and their populations circa 1920 were:

1. Baltimore (733k)
2. Montreal (619k)
3. Mexico City (615k)
4. Los Angeles (577k)
5. Toronto (522k)
6. Buffalo (507k)
7. San Francisco (507k)
8. Milwaukee (457k)
9. Newark (415k)
10. New Orleans (387k)
11. Minneapolis (381k)
12. Havana (364k)
13. Kansas City (324k)
14. Seattle (315k)
15. Indianapolis (314k)

In Alt-1915 (Alt-1916 by now), four of these cities do have MLB: #1 Baltimore, #6 Buffalo, #9 Newark, and #13 Kansas City.  Some of the remaining cities are non-starters for teams before the 1940s for various reasons (I'm considering a post about the pros and cons of expansion to various cities).

I don't imagine expansion before the mid 20's, though. Here are the same numbers for c. 1930, with the Alt-1915 teams removed:

1. Los Angeles (1.2M)
2. Mexico City (1.0M)
3. Montreal (819k)
4. Havana (728k)
5. San Francisco (634k)
6. Toronto (631k)
7. Milwaukee (578k)
8. Minneapolis (464k)
9. New Orleans (458k)
10. Seattle (365k)
11. Indianapolis (364k)
12. Rochester NY (328k)
13. Louisville (307k)
14. Portland OR (302k)

So, again, some of these teams are non-starters but I'm including them for completeness. Houston isn't too far below Portland but doesn't necessarily offer much advantage. 

Let's see if I can figure out transit times for some of these cities for the next relevant post. I think Minneapolis-St. Paul (St. Paul adds another 235k to the 1920 Minneapolis number and 272k to the 1930 number) may be somewhat further from other cities than I'd thought, though I still think it's much closer than New Orleans would be.
