Helsinki is a bilingual municipality with Finnish and Swedish as its official languages. The population consists of Finnish speakers, Swedish speakers, and speakers of other languages. Helsinki has hosted the 1952 Summer Olympics, the first CSCE/OSCE Summit in 1975, the first World Athletics Championships in 1983, the 52nd Eurovision Song Contest in 2007 and it was the 2012 World Design Capital. The city is recognized as a "Design City" in 2014 by UNESCO's Creative Cities Network. Helsinki has one of the highest standards of urban living in the world.

In an international Cities of Choice survey conducted in 2021 by the Boston Consulting Group and the BCG Henderson Institute, Helsinki was ranked the third-best city in the world to live in, with London and New York City coming in first and second.
