Total selection indices and their components in the Kursk Oblast, calculated from Crow's equations, are: Itot = = 0.403, I(f) = 0.345, Im = 0.043. The selection intensity was higher in rural than in urban populations. The levels of total selection and differential fertility in rural populations depended on the genetic and demographic structure of these populations. An increase of homozygosity in the rural populations (decreases in the mean square distance between spouses' birthplaces and in the frequency of long-range migrations, increase in ethnic assortativeness, etc.) increased the selection intensity.
