Sweden, officially the Kingdom of Sweden , is a Scandinavian country in Northern Europe. It borders Norway to the west and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund. At 450,295 square kilometres, Sweden is the third-largest country in the European Union by area, with a total population of over 9.8 million. Sweden consequently has a low population density of 21 inhabitants per square kilometre, with the highest concentration in the southern half of the country. Approximately 85% of the population lives in urban areas. Southern Sweden is predominantly agricultural, while the north is heavily forested. Sweden is part of the geographical area of Fennoscandia. The climate is in general very mild for its northerly latitude due to significant maritime influence, that in spite of this still retains warm continental summers.
