Distribution of surnames over the Alto Adige-Südtirol region according to local geographic, historical and linguistic features.

This paper aims at analysing the distribution of surnames over the Alto Adige-Südtirol, which is an Italian alpine sub-region coinciding with the province of Bolzano-Bozen. Two thirds of the Alto Adige-Südtirol inhabitants are German mother-tongue, whereas the remaining one third is Italian mother-tongue. There is also a minority represented by Ladin-speaking people.

Distribution of surnames and linguistic-cultural identities in Western Slovenia.

The following study compares the distribution of surnames in the populations of Western Slovenian municipalities, which were part of the Italian state until the end of the Second World War. The analyses have been carried out firstly by assessing the similarity of different populations to one another so as to verify possible aggregations; secondly, by figuring these relationships of similarity in a representation through unrooted tree (NJ); finally, by applying spatial autocorrelation to the distribution of surnames in the territory so as to highlight possible processes in the diffusion of people in the area under examination. On the whole, it seems likely that the population living in the area is geographically quite stable, although some differences may be noted depending both on the geography of the territory, particularly in the northern part, and on peculiar historical and socioeconomic conditions, which at the same time have characterized and modified the demographic structure of some of these municipalities.

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.

Distribution of surnames and identities in the Cimbro-Mòcheno communities of Italy.

The surnames of populations of the municipalities with Cimbro and Mòcheno origins are compared with each other and with other municipalities of the neighbourhood. This study starts from the supposition that a community of surnames shares a common cultural origin, maintained by reciprocal mobility. The analysis has been carried out by using estimates of the similarities between populations, the topological representations obtained by them and the spatial autocorrelation.

An analysis of the spatial distribution of surnames in the Lecco area (Lombardy, Italy).

The internal mobility of the population of the province of Lecco (Lombardy, Italy) was evaluated on the basis of the frequency of characteristic surnames in three territorial areas as a function of their geographical distance. Nearly three fourths of the patterns are statistically significant in one of the three areas, where the process of diffusion of surnames could be interpreted as due to socioeconomic factors. On the contrary, a similar distribution is less evident in the other two areas of the same territory.
