European Russia is the western and most populated part of the Russian Federation. It is geographically situated in Europe, as opposed to the country's sparsely populated and vastly larger eastern part, Siberia, which is situated in Asia, encompassing the entire northern region of the continent. The parts of Russia are divided by the Ural Mountains, the Ural River, and the Miass River, which bisect the Eurasian supercontinent. European Russia spans roughly 40% of Europe's total landmass, with over 15% of its total population, making Russia the largest and most populous country in Europe. The region is divided into six Federal districts.
