Maine

Settlement & growth (pre-1960)

Long before European arrival, Maine was home to several Algonquian-speaking nations, including the Wabanaki Confederacy—the Penobscot, Passamaquoddy, Maliseet, and Micmac—who lived along the coast and river valleys, subsisting on fishing, hunting, and seasonal agriculture. The Penobscot Nation’s ancestral seat on Indian Island near Old Town remains a cultural and political center today, with roughly 2,400 enrolled members statewide.

European colonization began in earnest in the early 1600s, with French and English explorers competing for the fur trade. The first permanent English settlement was established at Popham Colony (near present-day Phippsburg) in 1607, though it lasted only a year. More lasting were the fishing and trading posts at Monhegan Island and the settlement at York, founded in 1636. The region was contested between New France and New England for over a century, with raids and skirmishes shaping a defensive, independent-minded population.

After the American Revolution, Maine was part of Massachusetts until 1820, when it entered the Union as a free state under the Missouri Compromise. The early 19th century saw a wave of settlers from southern New England—primarily English-descended Yankees—who pushed inland along rivers like the Kennebec and Penobscot. Towns such as Augusta, Bangor, and Portland grew as lumber and shipbuilding hubs. The lumber industry drew a smaller but notable wave of Irish immigrants in the 1840s and 1850s, many of whom settled in Portland and Lewiston to work in mills and on the waterfront.

The late 19th and early 20th centuries brought a second wave of immigration: French Canadians from Quebec, who crossed the border in large numbers between 1860 and 1920 to work in the textile and paper mills of Lewiston, Biddeford, and Waterville. By 1900, roughly one-third of Maine’s population was of French-Canadian descent, a demographic legacy that remains visible today in the state’s Franco-American culture, surnames, and Catholic parishes. Other immigrant groups were small: a scattering of Swedish immigrants settled in the Aroostook County potato-growing region around New Sweden, and a few Italian and Polish families arrived in Portland, but Maine never experienced the mass European immigration that reshaped other Northeastern states.

Through 1960, Maine’s population remained overwhelmingly rural, white, and native-born. The state’s economy—timber, fishing, shipbuilding, and textiles—sustained a stable but slow-growing population. The Great Depression and World War II prompted some out-migration to industrial cities in southern New England, but Maine’s character as a quiet, homogeneous, and self-reliant place was firmly set.

Modern era (post-1965)

The 1965 Hart-Cellar Act, which reshaped U.S. immigration, had a minimal effect on Maine. The state’s foreign-born population remains the lowest in the nation at 1.8%, compared to the national average of 13.7%. The small immigrant communities that have formed since 1965 are concentrated in a few urban centers. Portland has seen the most visible change: a modest but growing Somali and East African community, numbering roughly 5,000, began arriving in the early 2000s as secondary migrants from other U.S. cities. Lewiston also received a wave of Somali refugees in the 2000s, now estimated at 3,000-4,000, making it one of the most notable African immigrant enclaves in northern New England. Asian (East/Southeast Asian) communities are tiny, at 1.0% of the state population, with small Vietnamese and Cambodian clusters in Portland. The Indian-subcontinent population is negligible at 0.1%.

Domestic migration has been more consequential than immigration. Since the 1970s, Maine has attracted retirees and second-home buyers from Massachusetts, Connecticut, and New York, drawn by lower property taxes, scenic coastlines, and a slower pace of life. This in-migration has concentrated in coastal towns like Kennebunkport, Camden, and Bar Harbor, as well as the Portland suburbs of Falmouth and Scarborough. The 2020 pandemic accelerated this trend, as remote workers from Boston and New York purchased homes in York County and the Midcoast region, driving up housing prices and fueling a cultural tension between newcomers and year-round residents.

Suburbanization has been modest by national standards. Portland’s metro area—the state’s only significant urban center, with about 550,000 people—has seen suburban growth in towns like Windham, Gorham, and Saco, but Maine lacks the sprawling exurbs common in other states. The state’s rural character persists: over 60% of Mainers live in towns with fewer than 10,000 people. The Hispanic population, at 2.1%, is small and dispersed, with no major enclave; the largest concentrations are in Portland and Lewiston, driven by Puerto Rican and Mexican migrants working in service industries and agriculture.
