REGIONAL DIFFERENCES IN STREET NAME STRUCTURES IN POLAND

Summary/Abstract: Abstract: Street names have long been of scholarly inter- est, yet their regional variation remains surprisingly un-derexplored, despite several compelling reasons to expect its presence. This article presents findings from a study of the regional differentiation in the structure of streetnames across Poland’s administrative regions (voivode-ships). Drawing on data from the TERYT register, the names were cleaned, coded, and subjected to quantitative analysis using similarity measures and hierarchical clus-tering methods. The results reveal that all voivodeshipsexhibit a similarly high degree of internal unevenness intheir street name structures, and – except in the case ofgeographical and topographical names – demonstrate a generally high level of inter-regional similarity. For both the full set of street names and the subset of geographical-topographical names, the analysis identified spatially coherent groupings of voivodeships with comparable naming structures. These groupings closely reflect the patterns of historical (relict) boundaries and the configuration of major physiographic regions.
