During the 1950s and 1960s, Soviet citizens were urged to settle in the Virgin Lands of the Kazakh Soviet Socialist Republic. The influx of immigrants, mostly Russians, skewed the ethnic mixture and enabled non-Kazakhs to outnumber natives. As a result, the use of the Kazakh language declined, but has started to experience a revival since independence, both as a result of its resurging popularity in law and business and the growing proportion of Kazakhs. The other nationalities included Ukrainians, Germans, Jews, Belarusians, Koreans and others; Germans at the time of independence formed about 8% of the population, the largest concentration of Germans in the entire Soviet Union. Kazakh independence has caused many of these newcomers to emigrate.
