How this ranking works

We rank every town by the share of residents aged 65 and older. Retirement, lake and coastal towns lead this list. The town with the highest figure ranks #1. For comparison, the figure for South Dakota as a whole is 18%.

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.
