This site´s home page gives general information about the GSM project and team. A panel on the right displays the following data:
DATA SOURCE
The data provided are from the 2001 population census carried out by the Instituto Nacional de Estatística (Madrid).
TOTAL NUMBER OF SURNAMES IN THE DATA BASE
The data base is made up of all the surnames in the 2001 population census for Galicia.
Since registers give two surnames per person, the total number results from adding first and second surnames, and does not therefore
represent the total number of bearers of those names.
DISTINCT SURNAMES IN THE DATA BASE
This is the number of different forms of surnames that appear in the 2001 census.
