In southern nh there are many Hispanic areas. The bottom half of NH is just a Boston/Portsmouth/Manchester suburb.
Way up north in the rural areas you have the standard couple of stores in every couple of towns.
Not really....NH is 95% white & about 2+% asian. There are no “hispanic areas” in the state. The state is less than 3% black & hispanic. In general southern NH is conservative & very wealthy. There are some problem spots in Manchester & Nashua.
Overall the state is very safe & the quality of life is outstanding. North of Concord, which is in central NH, it gets rural quick....you don’t have to go too far north. There’s only 1.3 million people in the state. My retirement place is up there & I can’t wait to decamp where I am right now and get up there.
In northwestern NJ the chain supermarkets are few and far between; the population is so scattered. Those places are nice to visit, but I couldn’t imagine living there (especially as a kid - you need a car to go anywhere).
