> Numerically, statistically, per capita, any way you want to slice it.
Per capita SF might beat NYC (couldn't find good sources and honestly I'm a little tired at the moment) but "Numerically" and "any way you want to slice it" NYC wins hands down. In 2015 it was estimated that San Francisco had 7,539 [1]. NYC, on the other hand, had 60,456 in 2016 [2].
I couldn't find many sources that differed much than these figures I found even though they're about a year separated.
