North Asia or Northern Asia, also referred to as Siberia, is the northern region of Asia, which is defined in geographical terms and is coextensive with the Asian part of Russia and consists of three federal districts of Russia: Ural, Siberian, and the Far Eastern. North Asia is bordered by the Arctic Ocean to its north; by Eastern Europe to its west; by Central and East Asia to its south; and by the Pacific Ocean and North America to its east. It covers an area of 13,100,000 square kilometres (5,100,000 sq mi), or 8.8% of Earth's total land area; and is the largest subregion of Asia by area, but is also the least populated, with a population of around 37 million, accounting for merely 0.74% of Asia's population.
