Distribution of surnames and linguistic-cultural identities of the Slovenian and German minorities of northeastern Italy

In this study we have compared the structure of surnames of Slovenian and German (Carinthian) minorities of northeastern Italy with other municipalities of the neighbourhood. The analysis has been carried out by using estimates of the similarities between populations and the topological representation obtained by them, as well as the spatial autocorrelation. On the whole, this research shows some distinctions which depend on the territorial geography, especially in the mountainous area. Moreover, movements of individuals in the limited zones of the plain are evident, probably due to socioeconomic conditions, the moving of the people and their change of dwelling. Finally, it is probable that different Slovenian dialects generated characteristic structures of surnames which were well preserved in the most peripherical municipalities of the territory.
