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.
