Together with the cities of Espoo, Vantaa, and Kauniainen, and surrounding commuter towns, Helsinki forms the Greater Helsinki metropolitan area, which has a population of over 1.5 million. Often considered to be Finland's only metropolis, it is the world's northernmost metro area with over one million people as well as the northernmost capital of an EU member state. After Stockholm and Oslo, Helsinki is the third largest municipality in the Nordic countries. Finnish and Swedish are both official languages. The city is served by the international Helsinki Airport, located in the neighboring city of Vantaa, with frequent service to many destinations in Europe and Asia.
Helsinki was the World Design Capital for 2012, the venue for the 1952 Summer Olympics, and the host of the 52nd Eurovision Song Contest in 2007.
Helsinki has one of the world's highest standards of urban living. In 2011, the British magazine Monocle ranked Helsinki the world's most liveable city in its liveable cities index. In the Economist Intelligence Unit's 2016 liveability survey, Helsinki was ranked ninth among 140 cities. On July 20, 2021, the American magazine Time ranked Helsinki one of the greatest places in the world in 2021 as a city that "can grow into a sprouting cultural nest in the future," and which has already been known in the world as an environmental pioneer. An international Cities of Choise survey conducted in 2021 by the consulting firm Boston Consulting Group and the BCG Henderson Institute raised Helsinki the third best city in the world to live, with London and New York City ranking the first and the second. Also, together with Rovaniemi in the Lapland region, Helsinki is one of Finland's most significant tourist cities in terms of foreign tourism.
