It varies based on where you live. I'm not in or near a major metro area, but we do have a Hindu temple within 2 miles of me, a couple of mosques not much further out, even a forest Buddhist temple, monastery, and meditation center within 10 miles. My neighbors across the street are from India.
I know people living in or around small cow towns that don't have any of that in their communities, but they are still aware of things. I know one farm couple who live way out and they're big fans of the old "Little Mosque on the Prairie" TV sitcom.
