The city of Portland, Maine, is the hub city of a metropolitan area in southern Maine, commonly known as Greater Portland or the Portland metropolitan area. For statistical purposes, the U.S. federal government defines three different representations of the Portland metropolitan area. The Portland-South Portland-Biddeford, ME Metropolitan Statistical Area is a region consisting of three counties in Maine, anchored by the city of Portland and the smaller cities of South Portland and Biddeford. As of the 2010 census, the MSA had a population of 514,098. A larger combined statistical area (CSA), the Portland–Lewiston–South Portland Combined Statistical Area, is defined as the combination of this metropolitan statistical area (MSA) with the adjacent Lewiston-Auburn MSA. The CSA comprises four counties in southern Maine. The Portland-South Portland Metropolitan New England City and Town Area is defined on the basis of cities and towns rather than entire counties. It consists of most of Cumberland and York counties plus the town of Durham in Androscoggin County.
The Portland-South Portland-Biddeford MSA is defined as consisting of Cumberland, Sagadahoc, and York counties. Portland, South Portland, and Biddeford are the three largest cities in this area and are defined as principal cities of the MSA. Other cities in the MSA are:

Owned and operated by the City of Bangor, the airport has a single runway measuring 11,439 by 200 ft (3,487 by 61 m). Formerly a military installation known as Dow Air Force Base, Bangor International Airport remains home to the 101st Air Refueling Wing of the Maine Air National Guard, although most of the Air Force's aircraft and people left in the late 1960s.
The airport owes its prosperity to its location on major air corridors between Europe and the East Coast of the United States.
State Routes in Maine
A state of the United States of America is one of the 50 constituent political entities that shares its sovereignty with the United States federal government. Because of the shared sovereignty between each U.S. state and the U.S. federal government, an American is a citizen of both the federal republic and of his or her state of domicile. State citizenship and residency are flexible and no government approval is required to move between states, except for persons covered by certain types of court orders (e.g., paroled convicts and children of divorced spouses who are sharing custody).
States are divided into counties or county-equivalents, which may be assigned some local governmental authority but are not sovereign. County or county-equivalent structure varies widely by state. Kentucky, Massachusetts, Pennsylvania, and Virginia use the official title of Commonwealth rather than State.
