Who are Catalans from Catalonia?
Catalans from Catalonia are a northeastern Iberian population associated with Barcelona, Girona, Lleida, Tarragona, the Pyrenees, the Ebro lands, and the Mediterranean coast. Catalan history includes Roman Hispania, medieval Catalan counties, the Crown of Aragon, Mediterranean trade, industrial Barcelona, and modern Catalan identity.
Catalan and Spanish are both widely used, with Catalan central to regional identity and public life. Catalonia has coastal, inland, Pyrenean, and metropolitan subregions, so the broad Catalonia reference is best read alongside more specific Catalan regional pages.
As a genetic reference, Spanish Catalonia Catalan is useful for comparison with Lleida, peri-Barcelona, Barcelones, Girona, Penedes, Valencia, Aragon, Cantabria, Madrid/Castilian, Balearic Catalan, and nearby southern French references.
What is Spanish Catalonia (Catalan) DNA closest to?
