The article is devoted to the study of geographical images of the administrative regions of Western Siberia, which have formed in the public consciousness of the population of Russia. The analysis of geographical images as group mental models of territories (which reflect both real and fictional, stereotypical and fantasy characteristics of them) has important practical significance, since they form the general everyday idea of this space and attitude to it. At the same time, administrative-managerial and personal decisions based on these mental representations are made in real space. The article reflects the results of a sociological study in which 685 people from 29 regions of Russia participated as respondents. Based on their surveys, the analyzed database of geographical images of administrative entities, the West Siberian Economic Region was formed. In the course of the study, not only the main geographical images of each of the 9 subjects of the Russian Federation studied were identified (for them, in particular, imaginal maps were compiled using the word cloud method, taking into account the significance of each image), but also erroneous ideas, stereotypical and even mythological images present in the philistine consciousness were identified. Also, in the course of the work, it was possible to identify patterns of differentiation of the mental space of Western Siberia, differences in information capacity and reliability of geographical images of different regions. The factors and mechanisms of forming people's ideas about different territories and the geographical picture of the world as a whole are determined. In particular, the phenomena of "privatization of images" and "inertia of image change" are characterized. Based on the genesis of geographical images, their classification is carried out with the allocation of 6 main types of geographical images. For each studied region, an analysis of the ratio of images of different types was carried out, which was graphically reflected using lip-stick diagrams, the configurations of which quite clearly reflect the degree of formation and typological orientation of the mental space of each region. An assessment of the formation, images, and their reliability was carried out, which showed significant regional differences. Analysis of the level of positivity and compliance with the goals of regional development of geographical images, which provides incentives for improving the media policy of the respective regions.
