Between 1906 and 1912, more than half a million ukraines and russians farms were started in Kazakhstan as part of the reforms of the Russian minister of the interior Petr Stolypin. By 1917 there were close to a million slavs in Kazakhstan, about 30% of the total population. 
Analysis of data on migrants who arrived during the Stolypin agrarian reform (1906-1912) on the territory of Kazakhstan shows that 83.1% of the settlers were from Ukraine, the rest came from the southern regions of Russia (16.8%).
