The spatial redistribution of population in the context of urban development has not yet been the topic of thorough research in Slovakia. Some research leading to the identification of processes of urban development and their impact to the spatial redistribution of population was carried out only in the Bratislava urban region but the knowledge of recent processes and trends in the regions of other cities and towns in Slovakia is rather limited. Since Bratislava has recorded dynamic economic development and regional disparities among the Bratislava region and other regions in Slovakia has been growing after the Velvet revolution, it is likely that the urban development and intensity of spatial redistribution of population processes are different than in the rest of Slovakia.
Therefore, the aim of this monograph is to examine and assess the processes of spatial redistribution of population in the context of urban development in the Košice functional urban region (FUR). Particular attention is paid to the role of migration in the spatial redistribution of population, both at the inter-regional and intra-regional level. This objective includes some basic partial goals:
- To assess the role of migration and natural reproduction of population in the total population growth of the region and the redistribution of population within the region.
- To identify the changes of position of the Košice FUR in stages and phases of selected urban development models, considering the development within the region as well as comparison of the development of the region as whole with other functional urban regions in Slovakia.
- To analyze the changes in migration trends in the Košice FUR as whole, at the level of its basic components (the core and the ring) and also at the level of individual communities within the region.
- To analyze the changes in the population structure and to assess its relation to the identified processes of spatial redistribution of population.
The research is aimed to capture the development in transition and post-transition period after the Velvet revolution in 1989. However, due to substantial changes in the spatial units of public administration in Košice between 1995 and 1996 and related availability of reliable statistic data, some partial analyzes are starting in 1996. The research is based on two basic sources of statistic data provided by Statistical office of the Slovak Republic: The Population Change in the SR published annually (ŠÚSR 1991 – 2013) and the results of population censuses that took place in 1991, 2001 and 2011 (ŠÚSR 1991, 2001, 2011). Since the data in The Population Change in the SR are adjusted on the basis of the censuses results after every census, to avoid the impact of these adjustments, some analyzes are carried out only in the period 2001 – 2010.
Higher administrative spatial units (districts and regions) in Slovakia in many cases do not reflect real functional relations and ties in space. Therefore, we decided to use functional urban region as main spatial unit for the research. The network of FURs was delimited by Bezák (2000) in Slovakia on the basis of daily urban systems concept. In terms of (daily) commuting, FURs are internally integrated and externally relatively closed. It means that majority of commuting flows (among the communities) takes place within the region and only minority crosses its border. That allows us to assume that the influence of various factors on intra-regional migration within the FUR is also relatively closed. Therefore, the network of FURs in Slovakia can be regarded as an appropriate regional system for the research of population redistribution at both, intra-regional and inter-regional level.
At the level of the region as whole, decisive role of natural reproduction of population in the total population growth was identified. Nevertheless, within the region the migration is the key factor of spatial redistribution of population and its significance has been growing during whole observed period. Also at the level of individual communities, the migration was identified as a decisive component of total population growth in growing majority of communities. Therefore, in the identification of the spatial redistribution of population processes, particular attention was paid to the migration of population.
Košice is the second most populous city in Slovakia, the metropolis of Eastern Slovakia and together with Bratislava it was included in the first category of centres in Slovakia by the hierarchization made by Slavík (1991). Nevertheless, we expected that the development after 1989 could weaken the position of Košice in relation to Bratislava which became the capital of the independent state and recorded strong economic growth related to the integration to the European structures. On the other hand, in Košice as well as majority of towns and regions in Slovakia, the transformation of economy was much more difficult and complicated.
The results of analyzes of the region’s position in the Stages of urban development model and the Differential urbanization model confirmed the aforementioned assumption. Urban development observed in the Košice FUR was similar with those observed in the categories of the regions of smaller town, while the Bratislava FUR underwent dynamic development significantly different from other categories of urban regions. This indicates that the urban development in Slovakia is not determined by the population size of the urban regions or its central cities as expected by the authors of the Stages of urban devel-opment model (Klaassen and Scimemi 1981) and Differential urbanization model (Geyer and Kontuly 1996) but rather regional disparities and the level of economic development of regions play a key role in the processes of spatial redistribution of population at least at the inter-regional level. These findings suggest the dynamics and intensity of migration processes in the Košice FUR might be lower than in the Bratislava FUR on the one hand, but on the other hand it can be assumed that in the Košice FUR identified relations of spatial redistribution of population and changes of population structure might be applicable to some extent to other FURs in Slovakia.
Considering inter-regional migration, the process of concentration of population from other region to the Košice FUR was alternating with the process of deconcentration that was taking place predominantly. However, the intensity of those processes was very weak. Much stronger dynamics and intensity of processes was observed at the intra-regional level. In the early 1990s the process of centralization of population from the region’s ring to its core was observed but in the mid-1990s it changed into the decentralization with rapidly growing intensity.
Ongoing process of decentralization of population resulted also to the changes at the local level. During whole observed period, the number of communities recording migration gains was growing with some fluctuations. The communities recording relatively high values of net migration, net migration rate and migration efficiency index created spatially almost compact area around the region’s core to the end of observed period.
At the beginning of observed period, there was only trivial or rather no correlation be-tween migration gains and the distance of communities from the region’s core. However, during 1990s the relation characterized as negative correlation emerged and its strength was growing till the end of observed period. The biggest migration gains, whether in terms of net migration or net migration rate were recorded in the communities located less than 15 kilometres from the centre of region’s core. Lower, but relatively big gains were recorded also in the category of communities located from 15 to 25 kilometres from the centre of the core. Categories of communities more distant from the core started to record migration gains in the mid 1990s but acquired values of net migration and net migration rate were relatively low there. This indicates the decentralization of population is the most intensive within the radius 25 kilometres from the centre of region’s core and at the greater distance its impact is much lower.
The key part of the study is also the assessment of the relations between changes in the structure of population and the observed processes of spatial redistribution of population. In this analysis, migration is represented by the net migration rate and the migration efficiency index. For more comprehensive understanding of factors influencing the changes in the structure of population the crude rate of natural increase was also included to the analyzes to represent the process of natural reproduction of population.
For the analyses of population structure data on religion, education and economic ac-tivity were available from the population censuses and data on age, sex and nationality of population were available from Statistical office of Slovak Republic annual publications (for age and sex from 1996 and for nationality from 1999; ŠÚSR 1996-2013, 1999-2013).
Changes in any of the observed features of population structure are not inconsistent with the expected impact of decentralization of population. In some cases (e.g. economic activity) the relationship observed is statistically very weak. However, it does not exclude the impact of decentralization. Especially characteristics based on statistical data from the censuses may be influenced by the circumstances and methodology of each census. Strong relationship was observed especially between the values of indicators of migration and changes in the age-structure and nationality (ethnic)-structure of population, where in both cases data were available from annual reports and so it was possible to observe the relation not influenced by corrections based on the census results. Relatively strong relationship was also observed with religious structure and educational structure of population but also the role of natural reproduction of population was significant in these cases.
Generally, it is possible to conclude that the process of decentralization of population identified on the bases of migration is to some extent responsible for the changes of popu-lation structure in the ring of the Košice FUR which is becoming more similar with the population structure in the core. Nevertheless, selective migration is influencing also the structure of population in the region’s core, which is particularly apparent in much faster ageing of population in the core whether compared with the ring or the population of whole Slovakia.
Although the monograph is focused on the topic that has not yet been the subject of thorough research in Slovakia, we believe it provides comprehensive overview based on relevant theoretical, methodological as well as empirical background. We hope, the research results presented in this monograph will be rich source of information for the reader but also the source of inspiration for further geographic research.
