Kazakhstan, which was formerly part of the Soviet Union, reflects this history through the ethnicity of itâ€™s people, language, and religion among other things. The primary ethnic group is Kazakh (approximately 53%) and ethnic Russians (approximately 30%). The state language of Kazakhstan is Kazakh which is spoken by the majority of Kazakhstaniâ€™s. The official language however is Russian which is considered the language of â€œinterethnic communicationâ€ and is spoken by almost all Kazakhstaniâ€™s. Families adopting from Kazakhstan may want to consider learning words in both Kazakh and Russian. The majority of Kazakhstaniâ€™s would claim to be either Muslim or Russian orthodox, with an almost even split between the two religions.
