The public sector, including publicly owned enterprises and the municipalities, plays the dominant role in the economy.http://www.economywatch.com/world_economy/greenland/export-import.html
Greenland is a massive island and autonomous Danish territory between the North Atlantic and Arctic oceans. Much of its land surface is covered in ice. Most of its small population lives along the ice-free, fjord-lined coast, particularly in the southwest. Its northerly position, largely above the Arctic Circle, results in natural phenomena such as summer’s midnight sun and winter’s Northern Lights.

However, you can be absolutely assured that although some towns are more popular than others, there aren’t any overrun towns in Greenland. There aren’t any tourism traps that you should steer clear off. You will experience the true Greenland everywhere! The great natural beauty and the meeting with the local population is right outside your hotel door.
