CORRELATION BETWEEN SPATIAL AND POPULATION CHANGES

The main subject of the paper is a proposal presenting the co-existing dynamic phenomena occurring in an urbanised area. The proposed method is based on an analysis of the trend and the intensity of changes concerning geolocation data. The input data were obtained from state statistical registers kept for administrative units (communes). The method was verified for a group of communes, creating a uniform urbanized area (a city and neighbouring communes). The data selected for the analysis include total population (demographic data) and residential floor space per person. The research assumes that the analysis of the dynamics of changes in the residential floor space per person provides the best indicator of changes occurring in the urbanised area. On the other hand, the population supplements information concerning changes in the urbanised area. In practice, a given area might become depopulated, and an increase in residential floor space per person will be observed. The growth of residential floor space per person can be also accompanied by an increase in population. Because of such complex dependencies, indicators have been proposed to visualise the dynamic changes occurring on the map.
