  The article presents the results of multivariate classification of Russian
regions by the indicators characterizing the population income and their
concentration. The clusterization was performed upon an author approach to
selecting the characteristics which determines the academic novelty in the
evaluation of regional differentiation by population income and the
interconnected characteristics. The performed analysis was aimed at the
evaluation of the real scale of disproportions in spatial development of the
country territories by the considered characteristics. The clusterization
results allowed to formulate the condition of a relatively "strong" position of
a group of high-income regions (the changes in the array of regions
constituting it is highly unlikely in the foreseeable future). Additionally
there has been revealed a group of Russian regions that the population is
struggling to live on quite low income. These so-called "poor" regions, within
the crisis conditions caused by Covid-19 are in need of additional public
support, without which their population will impoverish.
