Greenland is an autonomous territory of the Kingdom of Denmark and is the largest of the kingdom's three constituent parts by land area, the others being Denmark proper and the Faroe Islands. Citizens of Greenland are citizens of Denmark. They are thus citizens of the European Union (EU), although Greenland is not part of the EU. It is the world's largest island and lies between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. It shares a small 1.2-kilometre (0.75 mi) border with Canada on Hans Island. The capital and largest city is Nuuk. Kaffeklubben Island off the northern coast is the world's northernmost undisputed point of land – Cape Morris Jesup on the main island was thought to be so until the 1960s. Economically, Greenland is heavily reliant on aid from Denmark, which has averaged 5.4 billion kr. annually in the period 2019–2023, amounting to more than 20% of the territory's gross domestic product.
