Metropolitan peripheries or the issue of revitalisation of cities

Intensive development of the Upper Silesian region in recent years has resulted in the official establishment of the first urban organism in 2017 - the metropolis. The Upper Silesian and Zagłębie Metropolis is a diverse region which currently covers 41 communes. The subject of this paper, however, is not so much a description of differences as an attempt to capture the pace and course of revitalisation taking place in cities selected for analysis, in order to answer the question of how they affect the development of those cities and whether the fact that they belong to the same urban organism, which is the metropolis, determines their relatively balanced development. The following cities have become the subject of the comparative sociological-economic analysis in the selected area: Katowice, Zabrze, Tarnowskie Góry, Bytom and Ruda Śląska.
