People under 30 in Kazakhstan have only known one leader -- Nursultan Nazarbayev, who announced his resignation this week after shepherding the country from the Soviet era. "The word 'Nazarbayev' means something like the word 'parent'," said 18-year-old film student Madi Makanov, who lives in the country's largest city Almaty. Kazakhstan has a young population, with around 40 percent of people under 24, according to estimates based on UN figures.
