Regional indices get special attention because of their all-inclusive nature, which focuses on variables that are able to describe a region and indicate the level of its development. An analysis of a consumer's decision making indicates that the weights used for the regional variables considered and included in the index should not vary across regions. A regional index has been computed for 76 regions of Russia. The values of all the variables incorporated in this index are (i) scaled from 0 - 100, so that the index is independent of units of measurement, and (ii) weighted (the relevant weights were obtained from an experts' opinion survey). According to the adapted regional index, the best regions (which are the ones with the greater index values) are in the Central - Southern part of the country (with the exception of Sackha Republic, which is in the West). The regions with the lower index values are in the Western part of the country and in part of Central Russia (Mariel republic, Moldovia Republic, Perm region).
