The surname space of the Czech Republic: examining population structure by network analysis of spatial co-occurrence of surnames.

In the majority of countries, surnames represent a ubiquitous cultural attribute inherited from an individual's ancestors and predominantly only altered through marriage. This paper utilises an innovative method, taken from economics, to offer unprecedented insights into the "surname space...
