Hanover is one of the more culturally and racially diverse areas on the state. Thanks to Dartmouth College, DHMC, and a few large tech companies in the area, people come from all over the world to live and work here. I would actually say the area has a fairly large Indian population with a couple of great restaurants as well.
Hanover is one of a bunch of small towns that make up what we call the "Upper Valley." Home prices, property taxes, amenities, schools and diversity vary widely from town to town try to visit a few places to figure out where best to live and what your budget is.
