Summary statistics of HVS-I sequences in Spain and Portugal (excluding islands) carried out on main geographic regions.

All the computations were carried out on the common sequence segment of the HVS-I that ranges from 16024 to 16362. Population codes are as follows: a) Cantabrian coast = Galicia + Asturias + Cantabria + Basque Country + Navarra; b) Iberian Plateau = Castilla y León + Castilla La Mancha + La Rioja + Extremadura + Madrid + Aragón; c) Mediterranean coast = Murcia + Valencia + Catalonia; d) Andalusia; e) North Portugal = Viana do Castelo + Braga + Vila Real + Porto + Braganca; f) Centre Portugal = Aveiro + Viseu + Guarda + Coimbra + Castelo Branco + Leiria + Lisboa + Santarem + Portalegre; and g) South Portugal = Setubal + Evora + Beja + Faro. Note that sum of sample sizes of population sub-sets do not fully match with the total numbers mentioned above (4,588 from the literature + 3024 newly generated in the present study) because there was not enough geographic information for a few of them (the same applies to Tables 2 and 3).
