In 2000, the government sold one-third of the state-owned oil company Statoil in an IPO. The next year, the main telecom supplier, Telenor, was listed on Oslo Stock Exchange. The state also owns significant shares of Norway's largest bank, DnB NOR and the airline SAS. Since 2000, economic growth has been rapid, pushing unemployment down to levels not seen since the early 1980s (unemployment in 2007: 1.3%). The international financial crisis has primarily affected the industrial sector, but unemployment has remained low, and was at 3.3% (86,000 people) in August 2011. In contrast to Norway, Sweden had substantially higher actual and projected unemployment numbers as a result of the recession. Thousands of mainly young Swedes migrated to Norway for work during these years, which is easy, as the labour market and social security systems overlap in the Nordic Countries. In the first quarter of 2009, the GNP of Norway surpassed Sweden's for the first time in history, although its population is half the size.
