Migration Rates of Human Populations From Surname Distributions
Nature, 1987Migration is an important factor in the biological evolution of human populations, and surnames provide one of the simplest records of identification. The distribution of surnames can supply quantitative information on the structure of human populations.

SummaryA method is described for obtaining migration matrices from data on frequency distributions of transmissible traits in at least two different periods. In the present case, surname frequency distributions were used. In this way migration matrices describing rates of movement among nine areas of Sardinia were found for the period 1850–1970.

Distribution of surnames and identities in the Cimbro Mòcheno communities of Italy
Anthropologischer Anzeiger, 2002The 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

A study of the spatial distribution characteristics of Chinese surnames
American Journal of Human BiologyAbstractObjectivesThe spatial distribution of Chinese surnames is diverse and provides rich information about the evolution of human society. This study aims to propose several indices to quantify the spatial distribution characteristics of Chinese common surnames and to explore how these distributions are related to historical evolution.MethodsThis ...

Geography of surnames in the Azores: Specificity and spatial distribution analysis
American Journal of Human Biology, 2005In order to obtain a better understanding of the genetic structure of the Azorean population, a specificity and spatial distribution analysis was performed, based on 2,454 different surnames present in the Azorean telephone directory (2002). We considered as specific surnames those with an absolute frequency ratio equal to or higher than 50%.

An analysis of the spatial distribution of surnames in the Lecco area (Lombardy, Italy)
American Journal of Human Biology, 1999The 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
