People of Ukraine
The population of Ukraine is about 47.72 million. Ethnic Ukrainians make up about 73% of the total; ethnic Russians number about 22%, ethnic Belarusians number about 5%. The industrial regions in the east and southeast are the most heavily populated, and the urban population makes up about 67% of the population. Ukrainian and Russian are the principal languages. Although Russian is very widely spoken, in the 1989 census (the latest official figures) 88% of the population identified Ukrainian as their native language. The dominant religions are the Ukrainian Orthodox Church and the Ukrainian Greek Catholic Church (which practices Orthodox rites but recognizes the Pope as head of the Church). The largest part of the Ukrainian Orthodox Church belongs to the Moscow Patriarchy; however, following Ukrainian independence a separate Kiev Patriarchy was also established, which declared independence from Moscow. In addition to these, there is also a Ukrainian Autocephalous Orthodox Church.

The birth rate of Ukraine is declining. About 70% of adult Ukrainians have a secondary or higher education. Ukraine has about 150 colleges and universities, of which the most important are at Kiev, Lviv, and Kharkiv. There are about 70,000 scholars in 80 research institutes.
