Greenland
Both Greenlandic (an Eskimo–Aleut language) and Danish have been used in public affairs since the establishment of home rule in 1979; the majority of the population can speak both languages. Greenlandic became the sole official language in June 2009, In practice, Danish is still widely used in the administration and in higher education, as well as remaining the first or only language for some Danish immigrants in Nuuk and other larger towns. Debate about the roles of Greenlandic and Danish in the country's future is ongoing. The orthography of Greenlandic was established in 1851 and revised in 1973. The country has a 100% literacy rate.
