Stockholm is the capital of Sweden and the most populous city in the Nordic countries 949,761 people live in the municipality, approximately 1.5 million in the urban area, and 2.3 million in the metropolitan area.
Stockholm is the cultural, media, political, and economic centre of Sweden. The Stockholm region alone accounts for over a third of the country's GDP.
Stockholm hosts the annual Nobel Prize ceremonies and banquet. It is the seat of the Swedish government and most of its agencies, including the highest courts in the judiciary, and the official residencies of the Swedish monarch and the Prime Minister. It is the main centre for corporate headquarters in the Nordic region, and is home to some of Europe's top ranking universities.
The vast majority of Stockholm residents work in the service industry, which accounts for roughly 85% of jobs in Stockholm. The almost total absence of heavy industry (and fossil fuel power plants) makes Stockholm one of the world's cleanest metropolises. The last decade has seen a significant number of jobs created in high technology companies. A major IT centre is located in Kista, in northern Stockholm. Stockholm is also Sweden's financial centre, and home to Sweden's foremost stock exchange.
