Soviet Union [SEP] Nationalities and ethnic groups
The Soviet Union was an ethnically diverse country, with more than 100 distinct ethnic groups. The total population was estimated at 293 million in 1991. According to a 1990 estimate, the majority were Russians (50.78%), followed by Ukrainians (15.45%) and Uzbeks (5.84%). All citizens of the USSR had their own ethnic affiliation. The ethnicity of a person was chosen at the age of sixteen by the child's parents. If the parents did not agree, the child was automatically assigned the ethnicity of the father. Partly due to Soviet policies, some of the smaller minority ethnic groups were considered part of larger ones, such as the Mingrelians of Georgia, who were classified with the linguistically related Georgians.
