Russian Federation is a multi-national state with over 170 ethnic groups designated as nationalities, population of these groups varying enormously, from millions in the case of Russians and Tatars to under ten thousand in the case of Nenets and Samis. Among 83 subjects which constitute the Russian Federation, there are 21 national republics (meant to be home to a specific ethnic minority), 5 autonomous okrugs (usually with substantial or predominant ethnic minority) and an autonomous oblast. However, as Commissioner for Human Rights of the Council of Europe Gil-Robles noted in a 2004 report, whether or not the region is "national", all the citizens have equal rights and no one is privileged or discriminated against on account of their ethnic affiliation.
