Who are Castilians from Madrid?
Castilians from Madrid are associated with Spain's capital region in central Iberia. Madrid has grown through centuries of internal migration from across Spain, royal and administrative centralization, urban expansion, and modern metropolitan life, so a Madrid reference can reflect central Spanish ancestry with wider Iberian influences.
Spanish, historically Castilian, is the main language. Because Madrid is both a city and a region, this population average should be interpreted carefully and compared with nearby Castilian, Aragonese, Valencian, Catalan, Cantabrian, and Castilla-La Mancha references.
As a genetic reference, Spanish Madrid Castilian is useful for comparison with Valencia, Aragon, Cantabria, Catalonia, Castilla-La Mancha, Balearic Catalan, and other central or northeastern Iberian references.
