Maine's real gross state product in 2012 was estimated to be $45,986 which was $141,454 and 76% lower than the national state average, $187,440.
Maine has the 44th highest GSP out of the 50 states.Maine has a wealth of natural resources that support a large part of the state's economy. Nearly
89% of Maine's land area is covered by forest. As a result, the state is one of the world's leading producers of paper products. Mineral deposits within
the state include granite (used for construction throughout the United States), sand and gravel, and zinc.
Wooden shipbuilding was historically one of Maine's most important industries. Shipbuilding has greatly declined in recent decades, but the state now
produces warships at the Bath Iron Works. It is one of the state's largest single employers.
Large amounts of lobster and sardines are harvested from the waters off the coast. Rich farmlands to the west produce dairy products, poultry, eggs,
potatoes, blueberries, hay and apples.
Tourism remains a significant industry for the state. Resorts along Maine's coast and on its numerous islands attract many visitors to the state each
year.

The Bureau of Economic Analysis estimates that Maine's total gross state product for 2003 was $41 billion. Its per capita personal income for 2003
was $29,164, 29th in the nation.
Maine's agricultural outputs are seafood (notably lobsters), poultry and eggs, dairy products, cattle, blueberries, apples, and maple sugar. Aroostook
County is known for its potato crops. Western Maine aquifers and springs are a major source of bottled water (Poland Spring water is the Northeast's
preferred brand). Its industrial outputs are paper, lumber, and wood products, electronic equipment, leather products, food processing, textiles, and
tourism. Naval shipbuilding and construction remain key as well, with Bath Iron Works in Bath and Portsmouth Naval Yard in Kittery.
Maine ports play a key role in national transportation. Around 1880, Portland's rail link and ice-free port made it eastern
Canada's principal winter port, until the aggressive development of Halifax, Nova Scotia, in the mid-1900s. In 2001, Maine's largest city surpassed
Boston as New England's busiest port (by tonnage), due to its ability to handle large tankers.
Maine has a small trapping industry, which, with 3,157 resident trappers, is nevertheless larger than that of most Eastern states (Source: Portland
Press Herald, January 23, 2005. Note: Many trappers are part-time). The principal pelt taken by value is beaver. Historically, however, beaver trapping
was much more significant in the North Woods and Canadian Maritimes than the small industry of today and was the cause of much early wealth and many
trading settlements.
Maine has very few large companies that maintain headquarters in the state, and fewer than before due to consolidations and mergers, particularly in
the pulp and paper industry. Structurally, this could be a weakness in an economy that depends on extracting forest and sea resources, because decisions
that affect the long-range stability of the resource base are being made in distant locations which do not have to live on a day to day basis with
the consequences of their policies. Some of the very few large companies that do maintain headquarters in Maine include Fairchild Semiconductor (South
Portland) , IDEMaine Laboratories (a large veterinary biotech company in Westbrook) and the famous outdoor supply retailer L. L. Bean (Freeport). Maine
is also the home of The Jackson Laboratory, a non-profit institution and the world's largest mammalian genetic research facility.
