Warm weather matters. Florida and Arizona had the highest net migration of retirees in 2018.
Nine of the top 10 cities where retirees are moving are located in areas of the country that are not known for frigid weather. Denver, Colorado is the only city in the top 10 known for its more severe winters.
Retirees are cost-sensitive. In 2018, New York and California, two of the states with the highest cost of living, saw more seniors move out than move in.
