Quick answers
Questions people ask
What is the fastest-growing town in Maine?
Pittston (Kennebec County): it grew 19.0%, from 2,872 residents in April 2020 to an estimated 3,418 in July 2025. Eliot (+13.7%) and Kittery (+13.4%) follow.
How are these towns ranked?
By the percent change in residents from the Census Bureau’s April 2020 estimates base to its latest July 1 estimate, highest first, on the exact change: two towns shown with the same tenth of a percent keep the order of their unrounded figures, and only an identical change shares a rank (T). The base is the 2020 Census count redrawn on today’s town lines, so a town that annexed land since 2020 changes only by births, deaths and moves, not by the people it took in. How grades work.
Why isn’t my town on this list?
The list covers the towns TownRatings grades that had 2,500+ residents in the 2020 estimates base (141 in Maine). Census-designated places (unincorporated communities) have no Census Bureau estimates, so they never appear; a town incorporated since 2020, or one TownRatings merges with its twin township, isn’t listed either. Every town is on the Maine page.
