Here are the results of a very interesting study, which I participated in (along with 30,000 other people).
FWIW, I usually pronounce the o in “orange” like “a” in farce, though the longer I’ve lived outside New York, the less consistent I’ve become; call the place that I attend services “synagogue”‘; am proficient in Hebrew; never even heard of the word “tachlis” despite spending nine years in Orthodox yeshivot in New York; have people stay “with” me, not “by” me; say “Shabbat Shalom” and “Sukkot”; and would never, ever, consider naming my children “Mendy” or “Basia.”
