I just came across this very cool interactive map of languages spoken in New York City from the Endangered Language Alliance, with breakdowns by world regions, countries, language families, neighborhoods, etc.

From the project info:

With speakers of approximately 10 percent of the world’s 6000-7000 languages, the New York metropolitan area is the most linguistically diverse urban center in the world, probably in the history of the world.

This map is committed to representing in particular the smaller, minority, and Indigenous languages that are primarily oral and have neither public visibility nor official support.
