Miami also meets every single one of these metrics and has later night life than NYC. New Orleans has 24 hr night life. Vegas too.
Los Angeles has a higher foreign born population than NYC.
Las Vegas operates 24 hours a day if that's what you want.
I think what you mean by "World City" is actually just "Party Zone".
> except in a few specific areas
Yeah that's what I meant. I don't mean "the whole city is awake". I mean that there are amenities available in certain areas more or less 24/7, because of the density, there is a critical mass of 2nd and 3rd shift workers, and other "off-hours" workers who have different schedules and make use of it.
For those interested, here's where the alpha beta gamma and -/ /+[+] classification system comes from: https://en.wikipedia.org/wiki/Globalization_and_World_Cities...
You've got a very cosmopolitan view of what the world is. You should consider changing that.
On NYC, it has the best subway system in the US, but by global standards, it is filthy, disgusting, and unreliable. Any criticism leveled at the NYC subway is countered by Newyorkers saying "but we have 24/7 service while city XYZ does not!" However that same 24/7 service is arguably a big contributing factor for the NYC subway's many ills.
Seoul, and perhaps Tokyo and Hong Kong and other cities, arguably have an even more hardcore workaholic and party culture than NYC, but get along just fine with subways that don't run 24/7 so basic maintenance and cleaning can take place.
Edit: None of this comment was meant to detract, just a comparison in agreement to the city I'm nore familiar with. Maybe Toronto's different
For me, personally, I'm disappointed by how few world cities the US has. NYC and Chicago are really it. My silly benchmark for what makes a city a world city is that it operates 24hrs a day (at least parts of it). Chicago barely does but I think it counts. Everywhere else in the US just dies past 10pm and especially past 2am.
