A Multistage Agglomerative Approach for Defining Functional Regions of the Czech Republic: The Use of 2001 Commuting Data/ Vícestupňový aglomerační přístup k vymezení funkčních regionů České republiky: využití údajů o dojížďce z roku 2001

The issue of defining functional regions in the Czech Republic is presented in this paper, which contributes to both theoretical discussions (e.g. the modifiable areal unit problem) and practical applications (e.g. spatial administration, regional planning). A multistage agglomerative approach to functional regional taxonomy is applied, which has been used in Czech geographical research for the first time only recently. The regionalisation algorithm provided four optional solutions for this issue, based on the analysis of daily travel-to-work flows from the 2001 census. The resulting regions correspond to the micro-regional level and two additional tiers were identified at this level. The basic statistics for all variants are presented.
