Median household income is $97,344 in Boston versus $66,849 in Louisville, so typical pay runs 46% higher in Boston (about $30,495 more household income a year). Higher median income usually signals a stronger local job market and better negotiating leverage on salary. Remote workers should weigh this against cost of living rather than treating it as a direct personal benefit. For people who will actually work in town, Boston is the stronger labor market on paper. Louisville can still win if housing is cheap enough to offset the weaker median or if your specific role already pays well there.
