Located in the middle and northern latitudes of the Northern Hemisphere, the Soviet Union's 22.4 million square kilometers included one-sixth of the earth's usable land area. Its western portion, more than half of all Europe, made up 25% of its area; this, however, was where 72% of the people lived and where most industrial and agricultural activities were concentrated. The largest region was the lightly populated [[Siberia]], a land between the Urals and the Pacific that for centuries was infamous as a place of exile, a land of endless expanses of snow and frigid temperatures. | Located in the middle and northern latitudes of the Northern Hemisphere, the Soviet Union's 22.4 million square kilometers included one-sixth of the earth's usable land area.
