Southeastern Connecticut
The Southeastern Connecticut region comprises, as the name suggests, the southeastern corner of the state of Connecticut. It is sometimes referred to as New London County or by the tourist slogan Mystic and More. Southeastern Connecticut has historically been an area heavily dependent on traditional New England economic activities such as fishing, whaling, oystering, and the defense industry. In the present day, the area remains the primary home of the state's fishing and shellfish activity but has since diversified its economic base to include tourism, gambling, and other services. The area is home to the United States Coast Guard Academy in New London, a United States Navy base in Groton (also home to Electric Boat where the first U.S. nuclear submarine, , was launched, on January 21, 1954), a Pfizer research facility, and the Mohegan Sun and Foxwoods casinos.

There is an African-American presence in many municipalities, and many Asian communities in different parts of the region. The Pequot and Mohegan tribes both have their own reservations and casinos, along with a strong identity to their culture, though most tribal members only have partial Native American ancestry. Southeastern Connecticut is an ethnically diverse region. References
