Italian-American communities that still speak Italian/Sicilian/Napoli?

From my experience, Italian-Americans don't really speak the native tongue of their grandparents/great grandparents. I'd say that most Italian-Americans don't speak Italian/a italo-Romance language once you go past the 1970s.

What's crazy is that I heard that Italian, and other Italian languages, were pretty common in NYC during the early-mid 20th century. It wasn't uncommon to hear people speak the language(s) but I barely hear anyone speak it now. It's not like Spanish, or Russian in Coney Island.

I was wondering if anyone here knows any communities where the language(s) is/are still spoken by a decent number of people. I was really excited to hear about how many Italian-Americans lived in Staten Island when I lived there for a bit but they can't speak the language(s) at all.
