How this ranking works

We rank every town by population loss between the 2010 and 2020 censuses. Only towns that shrank are listed. The town with the lowest figure ranks #1. For comparison, the figure for Illinois as a whole is −0.1%.

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.
