Interactive: population change in Maine towns, 2010-2013

The U.S. Census Bureau's Population Division recently released updated population estimates for 533 Maine municipalities for the year 2013. These data, compared with population counts from the 2010 Census, indicate which Maine towns and cities are growing in population, and which are shrinking.

In the 2010 census, Maine's population was 1,328,361. The Census Bureau estimates that Maine as a whole lost 59 residents over the 2010-2013 interval – less than a hundredth of one percent of its population.

Still, some municipalities, especially in southern and coastal Maine, are seeing significant growth, while many others, mostly in rural areas of the state, are losing residents.

Greater Portland

Greater Portland saw the state's greatest population growth. While the city of Portland itself saw a modest gain in population (124 new residents between 2010 and 2013), most of the growth occurred in the city's suburbs. The five municipalities that posted the state's biggest population gains are all in this region.

The Census Bureau estimates that Cumberland and York Counties each gained 3,782 and 2,300 new residents, respectively, in the 2010 to 2013 period. With the exceptions of Bridgton and Frye Island, every town in these two counties posted population gains.

 

Greater Bangor

In the Bangor area, population gains in the towns of Hermon, Ellsworth and Orono were largely offset by losses in the city of Bangor, which had an estimated loss of 366 residents.

Penobscot County as a whole lost an estimated 559 residents in the 2010-2013 period, but Hancock County gained 427 people, with significant growth in Ellsworth.

Northern Maine

According to the Census Bureau, tiny Springfield, Maine in eastern Penobscot County was the northernmost municipality registering any population growth between 2010 and 2013, with a gain of 8 residents.

Aroostook County lost an estimated 1,815 residents. Presque Isle and Caribou, the county's two largest cities, trailed Augusta and Bangor in the ranks of Maine towns with the largest population losses.

Small towns, big impact

Another view of the data looks at population gains and losses in terms of annual percentage rates, which gives an idea of population changes on a per-capita basis. This emphasizes the effects of population gains and losses in comparatively small towns. For instance, Hope, in Knox County, gained 115 new residents between 2010 and 2013 — almost as many as Portland – in a town of only 1,651. That's more than 7 new residents moving in for every 100 residents who lived in Hope in 2010.

By contrast, Portland's 124 new residents, in a city of 66,318, add up to a paltry 0.06% annualized growth rate.

Census estimates of population changes in such small towns are less statistically reliable than for larger towns, and so this list excludes towns with fewer than 500 residents, such as Burlington in Penobscot County, where the estimate of 34 new residents out of 397 would have yielded a 3.0% annualized growth rate.
