Abstract

The paper analyses migration flows with the purpose of defining functional regions at a micro level. It proposes an innovative approach to the processing of migration data. It includes a reflection on local level migration analysis in relation to local labour markets, and it is inspired by time geographical concepts and research into human spatial behaviour. Relevant identified migration flows are those that occur when a migrant only changes the place of permanent residence, and does not necessarily need to change workplace or most of the localities within a daily timespace context. The paper uses these migration data to delineate local migration areas (daily spatial systems) of the Czech Republic through the application of a standard rule-based procedure of functional regional taxonomy.

5. Conclusion

Migration flows at a micro regional level represent a frequent and, in some regions, even a dominant component of intrastate migration flows. The migrants change their residences but, especially during the working day, their behaviour in a timespace is not considerably modified, with the exception of their location of return. This type of migration flow can be motivated by several factors, such as moving in with a life partner, moving into a different milieu, and these offer a person at a particular life cycle stage some comparative advantages; environmental, social, the elimination of wasted time during commuting, etc. It is not easy to identify these migration flows but the paper has relatively successfully attempted to present a procedure for doing so. The analysis of distances of intrastate migration flows in the Czech Republic between 2001 and 2012 has shown that 39.2% of migration flows between municipalities occurred at a distance up to 15 km, 55.7% up to 25 km, and 70.8% up to 50 km. These are undoubtedly high percentages, although it is not possible to identify precisely whether these numbers are made up of the formerly described migration type. However, the percentage form a majority, which can be proof of a lower level of labour force mobility in the Czech Republic, and evidence of the dominance of migration flows where migrants (economically active persons) do not change their workplaces. The remaining portion of migration flows; interregional migration, is a minor one.
