Slavs
Slavs are an Indo-European ethno-linguistic group who speak the various Slavic languages of the larger Balto-Slavic linguistic group. They are native to Eurasia, stretching from Central, Eastern, and Southeastern Europe all the way north and eastwards to Northeast Europe, Northern Asia (Siberia), the Caucasus, and Central Asia (especially Kazakhstan and Turkmenistan) as well as historically in Western Europe (particularly in East Germany) and Western Asia (including Anatolia). From the early 6th century they spread to inhabit the majority of Central, Eastern and Southeastern Europe. Today, there is a large Slavic diaspora throughout North America, particularly in the United States and Canada as a result of immigration.
Demographics of Russia
The Kazakhs in Russia are mostly not recent immigrants. The majority inhabit regions bordering Kazakhstan such as the Astrakhan (16% of the population are Kazakhs), Orenburg (6% of the population are Kazakhs), Omsk (4% of the population are Kazakhs) and Saratov (3% of the population are Kazakhs) oblasts. Together these oblasts host 60% of the Kazakh population in Russia. The number of Kazakhs slightly decreased between 2002 and 2010 due to emigration to Kazakhstan, which has by far the strongest economy in Central Asia (Russia does receive immigration from Kazakhstan, but they are mainly ethnic Russians); other Central Asian populations, especially Uzbeks, Tajiks, and Kyrgyz, have continued to rise rapidly. (Turkmen are an exception; citizens of Turkmenistan do not have visa-free access to Russia.)
