According to the Constitution, the Russian Federation is divided into 85 federal subjects (constituent units), 22 of which are "republics". Most of the republics represent areas of non-Russian ethnicity, although there are several republics with Russian majority. The indigenous ethnic group of a republic that gives it its name is referred to as the "titular nationality". Due to decades (in some cases centuries) of internal migration inside Russia, each nationality is not necessarily a majority of a republic's population.
