Russia – Ethnic groups and languages, Encyclopedia Britannica „"Although ethnic Russians comprise more than four-fifths of the country's total population, Russia is a diverse, multiethnic society. More than 120 ethnic groups, many with their own national territories, speaking some 100 languages live within Russia's borders."”
Glenn E. Curtis (ed.): Russia - Natural Resources. Washington, D.C.: Federal Research Division of the Library of Congress, 1998. (Hozzáférés: 2021. június 25.) „"Russia is one of the world's richest countries in raw materials, many of which are significant inputs for an industrial economy. Russia accounts for around 20 percent of the world's production of oil and natural gas and possesses large reserves of both fuels. This abundance has made Russia virtually self-sufficient in energy and a large-scale exporter of fuels."”
N. Sönnichsen: Natural gas - countries with the largest reserves 2009-2019. Statista, 2021. június 15. (Hozzáférés: 2021. július 2.) „"Russia has the largest proved natural gas reserves in the world. As of 2019, it had 38 trillion cubic meters worth of the fossil fuel, four trillion cubic meters more than ten years prior."”
Russian. University of Toronto. (Hozzáférés: 2021. július 9.) „"Russian is the most widespread of the Slavic languages and the largest native language in Europe. Of great political importance, it is one of the official languages of the United Nations – making it a natural area of study for those interested in geopolitics."”
