That “exurban” shift has become increasingly popular across the state and country, U.S. Census Bureau data shows, as people eschew major urban areas.

Scarborough, Windham, Gorham and Westbrook are growing rapidly — Portland isn’t. Between 2020 and 2023, Maine was the fastest-growing state in New England. More than ever, community planning is going to be crucial, said Joe Oliva, outreach and communications director for GrowSmart Maine.
