A focused population profile of Cantabrians, their northern Iberian background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Cantabrians are the people of Cantabria on Spain's northern Atlantic coast, between Asturias, the Basque Country, Castile and Leon, and the Bay of Biscay. Cantabrian history includes ancient Cantabrian groups, Roman conquest, mountain valleys, maritime towns, pastoral communities, and northern Spanish regional identity.
Spanish is the main language, with local Cantabrian speech traditions. Cantabria's position between the Atlantic coast, Castile, Basque-adjacent regions, and eastern Iberia gives it a distinctive northern Iberian comparison profile.
As a genetic reference, Spanish Cantabria Cantabrian is useful for comparison with Valencian, Madrid Castilian, Catalan Pirineu, Catalan, La Rioja, Aragonese, Castilla-La Mancha, and northern Iberian regional references.
In the World Genetics modern G25 comparison, the closest non-self match for Spanish Cantabria (Cantabrian) is Spanish Valencia (Valencian). Other nearby references include Spanish Madrid (Castilian), Spanish Catalonia Alt Pirineu (Catalan), Spanish La Rioja (Riojan), and Spanish Aragon (Aragonese). This gives the Spanish Cantabria (Cantabrian) profile its nearest modern genetic context inside the current reference database.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Cantabrian is best interpreted as a northern Iberian profile, with Valencian, Madrid/Castilian, Catalan, La Rioja, Aragonese, and Castilla-La Mancha references nearby.
The heatmap should emphasize Cantabria, northern Spain, Valencia, Madrid, Catalonia, La Rioja, Aragon, Castilla-La Mancha, and the Bay of Biscay region.
The closest non-self match in this World Genetics comparison is Spanish Valencia (Valencian). Other nearby references include Spanish Madrid (Castilian), Spanish Catalonia Alt Pirineu (Catalan), Spanish La Rioja (Riojan), and Spanish Aragon (Aragonese).
In the current modern G25 reference set, Spanish Valencia (Valencian) is the closest listed match to the Spanish Cantabria (Cantabrian) average after removing Spanish Cantabria (Cantabrian) itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Spanish Cantabria (Cantabrian) G25 average, giving the closest-match results a geographic view.
