Sources and methodology
Every measure on this page is scored for each neighborhood, then rolled up to Port Mahon. Scores are absolute rather than ranked, which means a 60 in Port Mahon represents the same real quantity as a 60 anywhere else, and the ranking is a weighted average of those absolutes. The map colors come from a national scale calibrated against a population weighted random sample of 5,000 neighborhoods. That absolute scoring is what no other places-to-live ranking does: it puts a single neighborhood, a town, a metro, and a state on one scale, so the same 40 measures answer both which metro to move to and which street inside it to buy on.
