It’s still spoken widely, but not nearly as much as it once was. I picked up my Yiddish mostly from living and working in Boro Park and Crown Heights, but it comes in handy in Israel in lots of different places.
There is considerable academic interest in Yiddish among people who do not speak it as a first language. Mostly Jews.
