Connecticut Experienced an Increase in Voter Turnout in the 2025 Election
From the 2021 to 2025 municipal election, voter turnout increased from 32% to 36% statewide. This represents almost 85,000 additional voters in the most recent election. Of the 158 towns that had a municipal election in both 2021 and 2025, almost three in four saw a higher turnout in 2025. In this blog post, we explore differences in voter turnout by town.
We will refer to both “percent change” and “percentage point change” throughout this post.
Percent change represents how much a value increases or decreases relative to its starting point. For example, if voter turnout increased from 15% to 20%, that represents a 33% increase, calculated as (20% - 15%) / 15%.
Percentage point change represents comparison by simple subtraction. For example, if voter turnout increased from 15% to 20%, that represents a 5 percentage point increase, calculated as 20% - 15%.
Three in Four Towns Experienced an Increase in Voter Turnout from 2021 to 2025
The maps below display voter turnout by town in 2021 (left) and 2025 (right). Both use the same scale, making it easy to see how many towns move from gold (lower turnout) to gray (medium turnout), and others from gray to green (higher turnout). A few towns even jump from gold to green between the two election years.
Voter Turnout More Than Doubled in Four Towns and Increased by Over 50% in Eighteen Towns
Many towns saw increases of over 50% in voter turnout from 2021 to 2025. Bridgewater experienced a 166% increase from 24% to 63%, followed by Middlebury (149% increase, 19% to 47%), Deep River (140% increase, 24% to 58%), and Sprague (132% increase, 21% to 50%).
