The Nordic countries make up a region in Northern Europe, sometimes called the Nordic region, consisting of Denmark, Finland, Iceland, Norway and Sweden and their associated territories which include the Faroe Islands, Greenland, and Åland. In English, Scandinavia is sometimes used as a rough synonym for the Nordic countries.
The region's five nation-states and three autonomous regions share much common history as well as common traits in their respective societies, such as political systems. Politically, Nordic countries do not form a separate entity, but they co-operate in the Nordic Council. Linguistically, the area is heterogeneous, with two unrelated language groups, the North Germanic branch of Indo-European languages and the Baltic-Finnic and Sami branches of Uralic languages. The Nordic countries have a combined population of approximately 25 million spread over a land area of 3.5 million km² (Greenland accounts for 60% of the total area).
