There are quite a few words of Yiddish origin in English, for example some more common ones (at least to me):
However, is there a significant correlation between certain social groups and their (non-)usage? In other words, is belonging to a particular social group indicative of using these words? I already know that this is (supposedly) restricted mainly to American English. Moreover, I personally understand many of these words but only rarely use them actively-- I'm unsure if this is typical or not for most speakers of (American) English.
