Depends on the area. You'll find speakers of lots of foreign languages all over in NYC or coastal California. What might be unusual in the US though is that it's a big country in both population and geographic size, and yet the amount of regional variation in the primary tongue is quite limited. I think the UK and Germany have considerably more variation, even though they're smaller countries.
