You do hear about it more in warmer cities, but the city with the largest homeless population is actually NYC by quite a large margin.

I wonder if they have an aggregate comparison of warm vs cold cities. I'd still consider NYC on the warmer side (with the gulf stream on the coast) when comparing it to the midwest or even Albany. For example, even going from Pittsburgh to Connecticut can be an increase of 20 degrees due to the gulf stream even though you are going slightly north.

Per capita? NYC is 2x larger than any other city.

LA/Los Angeles county (what the prior link uses) is a little larger than NYC, 10 million vs 8 million respectively.

I would also be interested in per capita per city. Even more so for aggregates of cold vs warm cities overall.

There is no comparison. LA county is the majority of the LA metro, while NYC is the minority.

The most meaningful comparison is CSA:

NY is 22.5M

LA is 18.7M

I think many people prefer the MSA definition over the CSA, CSA feels like a bit of a stretch in many of its definitions. Are San Jose and San Francisco one entity, or two? CSA says one, MSA says two.

Consider that someone who lives between them could have a 30 min. commute to a job in both. There's definitely a case to be made for some cases to use the concept that encompasses that.

Having lived and worked in the Bay Area I would definitely say they are one entity socially and economically. It was not unusual to have people live in San Jose and commute to SF, nor vice versa.

By contrast, Sacramento was clearly not part of that unit, even though it isn’t _that_ much further away. There’s a notable gap between the cities, and the cross-commute rate was near zero. (Emphatically NOT zero, there were some people who commuted in from Sacramento, but those were rare, and I never heard of anyone commuting the other way).
