I feel reasonably confident that there are just as many languages spoken in just Los Angeles county, if there are any parallels to NYC:

Also Sweden’s population is about the size of Los Angeles county. Every time I see Scandinavia held up as something to aspire to folks should remember how small and historically homogenous these countries are.

Comparing the US to the EU as a whole is a much more accurate way to look at things, with us states being akin to eu member countries.
