Moreover, the fact that women are more likely to complete higher education is associated with a greater tendency to leave smaller towns and migrate to metropolises, and then remain there. This leads to situations in which in smaller towns and municipalities there is often a radical surplus of men over women - according to the National Census, this proportion can amount to a dozen or so percent advantage of men over their peers.

This cannot be blamed on too high expectations on the part of the fair sex, because the selection of couples based on similarity in status is not an invention of modernity or supposedly of "bad feminists". So we can say that the reason is objective.
