Greenland is a self-governed Danish territory. An Arctic island nation located in the continent of North America, both geographically and ethnically; politically and historically, however, Greenland is closely associated with Europe. The Atlantic Ocean and Iceland lie to Greenland's Southeast; the Greenland Sea to the East; the Arctic Ocean to the North; Baffin Bay and Canada to the West. Greenland is the world's largest island, and is the largest dependent territory by area in the world. It also contains the world's largest national park. About 81 percent of its surface is covered by ice, known as the Greenlandic ice cap. Nearly all Greenlanders live along the fjords in the south-west of the island, which has a milder climate. Most Greenlanders have both Kalaallit (Inuit) and Scandinavian ancestry, and speak Greenlandic (Kalaallisut) as their first language. Greenlandic is spoken by about 50,000 people, which is more than all the other Eskimo-Aleut languages combined. A minority of Danish migrants with no Inuit ancestry speak Danish as their first language. Both languages are official, with the West Greenlandic dialect forming the basis of the official form of Greenlandic.
