How this ranking works

We rank every town by the median age of residents. College towns rank high here, because students pull the median down. The town with the lowest figure ranks #1. For comparison, the figure for South Dakota as a whole is 38.0.

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.
