Moving to nice weather

U.S. residents have been moving en masse to places with nice weather. Well known is the migration towards places with warm winters, which is often attributed to the introduction of air conditioning. But people have also been moving to places with cooler, less-humid summers, which is the opposite of what is expected from the introduction of air conditioning. Nor can the movement to nice weather be primarily explained by shifting industrial composition or by migration of the elderly. Instead, a large portion of weather-related movement appears to be driven by an increased valuation of nice weather as a consumption amenity, probably due to broad-based rising per capita income.
