Norway officially the Kingdom of Norway, is a Nordic country in Northern Europe occupying the western portion of the Scandinavian Peninsula, as well as Jan Mayen and the Arctic archipelago of Svalbard. Norway has a total area of 385,252 square kilometres and a population of about 4.8 million. It is one of the most sparsely populated countries in Europe. The majority of the country shares a border to the east with Sweden; its northernmost region is bordered by Finland to the south and Russia to the east; and Denmark lies south of its southern tip across the Skagerrak Strait. The capital city of Norway is Oslo. Norway's extensive coastline, facing the North Atlantic Ocean and the Barents Sea, is home to its famous fjords. The Kingdom of Norway also includes the Arctic island territories of Svalbard and Jan Mayen. Norwegian sovereignty over Svalbard is based upon the Svalbard Treaty, but that treaty does not apply to Jan Mayen. Bouvet Island in the South Atlantic Ocean and Peter I Island and Queen Maud Land in Antarctica are external dependencies, but those three entities do not form part of the kingdom.
