Some very odd comments going on in this thread currently. New Hampshire is a safe place to live and raise a family. While people can be standoffish here, generally they are kind. I wouldn't anticipate any issues regarding your family status. Again, generalizing, but people here tend to leave others alone and not force their religious opinions on others. It is one of the least religious states in the country - for that reason it leans "progressive" on many social issues.

It is conservative here relative to the rest of New England. The weed thing is mostly a result of financial issues stemming from the tax dependence on state run liquor stores. Folks brought up that we've got a Republican governor. Vermont also has a Republican governor. In 2019, all governors in New England except for Rhode Island were in fact Republican. Political party affiliation matters little here.

Cost of living here is high due to high energy prices and lack of real estate development combined with high demand. COL almost certainly eats any tax savings you'd earn by living here compared to neighboring Massachusetts. Infrastructure and social programs are substantially better in MA. It is also much more liberal in every respect. It is cold in New Hampshire, brutally so at times. The road salt can eat cars quickly, so maintenance costs can be higher. People seem move here for the quiet and outdoors focused lifestyle. If that's not you, I'd take a closer look at some other states!
