How this ranking works

We rank every town by population growth between the 2010 and 2020 censuses. These are official census counts, not estimates. The town with the highest figure ranks #1. For comparison, the figure for Connecticut as a whole is +0.9%.

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.
