How this ranking works

We rank every town by the median age of residents — often lake, mountain and retirement towns. The town with the highest figure ranks #1. For comparison, the figure for Montana as a whole is 40.4.

Only towns with at least 2,500 residents are ranked; Census estimates for smaller places are too uncertain. Population and income: U.S. Census Bureau American Community Survey 5-year estimates. Town photos: Wikimedia Commons, credited on each town’s page.
