Maine Population 2018

1,341,582

At the very northeastern tip of the United States is the state of Maine: a land known for its mountainous terrain and rocky coastline on which there is perhaps the one thing that Maine is famous for outside of its own country (other than Stephen King of course) -- the Maine Lobster. Maine is also the 41st most populated state in the US, with an estimated population of 1.34 million in 2018.

The varying landscape results in a very sparsely populated territory but in terms of pure numbers, the 2010 Census revealed that there were 1,328,361 people living in Maine. A further estimate in 2011 suggested that those numbers had decreased slightly to 1,328,188, making Maine the 41st most populous state in the country.

As a result of that fluctuation, the population of Maine in 2016 is a little hard to pinpoint, but current estimates show there are now 1,329,328 people living in the state, a slight rise from the last Census. Maine currently has one of the slowest population growth rates in the country of only 0.03%, which ranks 48th out of 50.

Maine Population Density and Area

Maine has a current population density of just 43.1 people per square mile, over an area consisting of 35,380 square miles, which makes it the least densely populated state in New England, the American northeast and the eastern seaboard, as well as all states with an Atlantic coastline and all of those states east of the Mississippi River.

The Greater Portland metropolitan area is the most densely populated in the state and claims 40% of Maine's total population. Much of Maine is comprised of uninhabited lands in remote parts of its interior.

The largest county in Maine by population size is Cumberland County. The most populated city in Maine is Portland with a population of over 67,000 individuals.

Maine Demographics

Age/Sex, Race, Religion

The median age of the popoulation in Maine is 44 years of age, and the states male to female ratio is approximately 51% female to 49% male.

In terms of racial diversity, Maine has a population consisting of 94.8% Caucasians, 2% two or more races, 1.2% African Americans, 1.1% Asians, and .8% other races including Natives.

When it comes to religious preferences, Maine has 60% of its population affiliated with a Christian based faith, 7% affiliated with a non-Christian based faith, and 31% unaffiliated with any faith.

Maine Boundary, Census, and Statehood History

Although geographically separate, Maine was legally part of Massachusetts from early Colonial times until March 15, 1820, when it was admitted as a separate State. The far northern portion of Maine was in dispute with Canada until the present boundary was agreed to in 1842.

Census coverage included virtually all settled portions of Maine from 1790 on, with the Maine counties reported separately from those of Massachusetts proper.

Maine Population Chart

Maine Population History

Its location at the edge of the new world means that the earliest recorded population figures were healthier and more stable than they may have been in other parts of the country.

The first set of available figures date back to 1790 and at the time, the population of Maine was recorded at a healthy 96,540. The following two censuses resulted in population increases of over 50%, and by 1810, it was shown that 228,705 people resided in the state.

From this point, the changes in population fluctuated somewhat but the overall picture was one of healthy growth. By the time the 20th century rolled in, Maine’s population had grown to a figure of 694,466. Further rises followed and in the present day, the population of Maine in 2016 had edged past 1.3 million.

Maine Population Projections

Occasional decreases in the overall numbers within the state, as well as one of the slowest population growth rates in the US, mean that it is relatively difficult to judge the exact population of Maine in the future. In terms of population and growth, this is one of the least remarkable states in the union, and while the overall picture is one of growth, only the 2020 census will give a more accurate picture.

It is projected that Maine's population will peak in 2020 at 1.332 million people, and then fall beyond that to 1.326 million. It's also estimated that the age composition in the state will change dramatically, as 26% of the population currently consists of people under 19. By 2030, it's estimated that this group will make up just 21% of the population. Meanwhile, the population over 65 continues to grow.
