At 450295 km2 , Sweden is the third-largest country in the European Union by area , with a total population of 10.0 million . Sweden consequently has a low population density of 22 PD/km2 , 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 .
