As of 2008, Maine has an estimated population of 1,321,504, which is an increase of 6,520, or 0.5%, from the prior year and an increase of 46,582, or 3.7%, since the year 2000. This includes a natural increase since the last census of 6,413 people (that is 71,276 births minus 64,863 deaths) and an increase due to net migration of 41,808 people into the state. Immigration from outside the United States resulted in a net increase of 5,004 people, and migration within the country produced a net increase of 36,804 people. The population density of the state is 41.3 people per square mile.
Maine is a very popular tourist destination, but it also experiences harsh winters, and consequently, the great temporary influx of visitors occurs during the warmer months. Many of these visitors establish an alternate secondary residence in Maine during the warm months and then depart for their primary residence in the off-season. These are the summer people of Maine lore. Official census figures normally count a person as a resident only once, at the place of the primary home. Therefore, there are some situations in which official census figures could be misleading for Maine. For example, some communities may have a much larger seasonal retail sector than their official, small population figure would imply.
The mean population center of Maine is located in Kennebec County, in or near the town of Mount Vernon. The Greater Portland metropolitan area is the most densely populated with nearly 20% of Maine's population. As explained in detail under "Geography", there are large tracts of uninhabited land in some remote parts of the interior.
The largest ancestries in the state are: English American (21.5%), Irish (15.1%), French or French Canadian (14.2%), American (9.4%), and German (6.7%).
Maine is second only to New Hampshire in the percentage of French Americans among U.S. states. It also has the largest percentage of non-Hispanic whites of any state and the highest percentage of current French-speakers who come from Quebec. Franco-Mainers tended to settle in rural northern Maine (particularly Aroostook County) and the industrial cities of inland Maine (especially Lewiston), whereas much of the midcoast and downeast sections remain mostly of British heritage. Smaller numbers of various other groups, including Italian and Polish have settled throughout the state since the early 20th c. immigration waves.
The 2000 Census reported 92.25% of Maine residents age 5 and older speak English at home. Census figures show Maine has a greater proportion of people speaking French at home than any other state in the nation, a result of Maine's large French-Canadian community, who migrated from adjacent Quebec and New Brunswick. 5.28% of Maine households are French-speaking, compared with 4.68% in Louisiana. Spanish is the third most spoken language at 0.79%, followed by German at 0.33% and Italian at 0.12% [4].

Maine receives passenger jet service at its two largest airports, the Portland International Jetport in Portland, and the Bangor International Airport in Bangor. Both are served daily by many major airlines to destinations such as New York, Atlanta, and Orlando. Essential Air Service also subsidizes service to a number of smaller airports in Maine, bringing small turboprop aircraft to regional airports such as the Augusta State Airport, Hancock County-Bar Harbor Airport, Knox County Regional Airport, and the Northern Maine Regional Airport at Presque Isle. These airports are served by US Airways Express with small 19 to 30 seat planes. Many smaller airports are scattered throughout Maine, only serving general aviation traffic.
Interstate 95 runs through Maine, as well as its easterly branch I-295. In addition, U.S. Route 1 starts in Fort Kent and runs to Florida. The eastern terminus of the eastern section of U.S. Route 2 starts in Houlton, near the New Brunswick, Canada border to Rouses Point, New York, at US 11 . There is also another US 2A connecting Old Town and Orono, Maine, primarily serving the University of Maine campus. U.S. Route 2, Route 6 and Route 9 are often used by truckers and other motorists of the Maritime Provinces en route to other destinations in the United States or as a short cut to Central Canada.
The Downeaster passenger train, operated by Amtrak, provides passenger service between Portland and Boston's North Station, with stops in Old Orchard Beach, Saco, and Wells. The Downeaster makes five southbound trips and five northbound trips every day.
Seasonal passenger excursions between Brunswick and Rockland are operated by the Maine Eastern Railroad, which leases the state-owned Rockland Branch rail corridor.
Freight service throughout the state is provided by a handful of regional and shortline carriers: Pan Am Railways (formerly known as Guilford Rail System), which operates the former Boston & Maine and Maine Central railroads; St. Lawrence and Atlantic Railroad; Maine Eastern Railroad; Montreal, Maine and Atlantic Railway; and New Brunswick Southern Railway.
