Bottom line: Boston, MA leads this ranking for clear, data-backed reasons — but the "best" city depends on your priorities.

If you're seriously considering a move, use our salary calculator to model your specific income against these numbers. There's an argument to be made — and I think the data supports it — that the cities getting all the attention right now are exactly the wrong places to move. The spotlight drives migration, migration drives demand, demand drives costs, and eventually the value proposition disappears. Meanwhile, cities like this one keep quietly being affordable, and the people who find them early are the ones who benefit most.
