The total selection index for Ukrainians living in Kharkiv equal 0.26, for Russians it is 0.32, and for the group formed from representatives of rare nationalities this index is 0.75. In a group of women with secondary education total selection index is 0.26, in a group with highest education it is 0.35. Conclusions.

Selection indexes differ in ethnic groups and in groups with different levels of education.
