Demographic disproportions of the new administrative-territorial system of the Lviv Oblast

Анотація

The concept of «demographic disproportions of the administrative-territorial system» is defined as the differences between territorial communities in terms of population, population distribution in central and other settlements, population density, and density of the settlement network, which is the result of diversity of natural and geographical conditions, population-recovery and migration processes. The new administrative-territorial division of Lviv Oblast consists of 73 communities in seven districts. They are characterized by sufficiently contrasting demographic parameters: number and density of population, natural population growth, relative migration balance, level of urbanization, and density of settlement network. The article proposes a method of assessing demographic disproportions between territorial communities using coefficients of deviation from mean statistical values, as well as the standard deviation. For Lviv Oblast, it revealed large disproportions in the number of the population, population density, and population of the center of territorial community; average disproportions by area, number of settlements, and density of the settlement network; and small according to population of territorial communities and population of their centers, without considering Lviv, as well as population density, not taking into account the Lviv community. According to the types of territorial communities, the greatest demographic disproportions were found between urban communities and the lowest between village and urban-type settlement communities. The hierarchical-clustering method was used to group the territorial communities according to fourteen relative values and deviations from the statistical average. Eight clusters were identified, which were united into three groups. The Lviv community with the population of 790,500 people, which should become the basis of the future Lviv agglomeration, was designated separately. According to the spatial patterns, the Lviv agglomeration could include the Zymna Voda village community, which is functionally connected with Lviv and is in sharpt contrast to the other village communities. Demographic disproportions between the territorial communities must be accounted for when charting out a regional development strategy of Lviv Oblast, with a differentiation by types of territories. Also, the results of our research may be used in designing special approaches to assessing the financial capacity of similar communities and planning their spatial development. In particular, this is relevant for the optimization of educational and healthcare institutions, centers of administrative services in communities, work of public transport, and the organization of municipal services.
