A focused population profile of Greeks from Attica, their central Greek background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Greeks from Attica are associated with Athens, Piraeus, the Attic peninsula, and surrounding areas of central Greece. Attica has an ancient Greek urban history, Byzantine and Ottoman layers, Arvanite-speaking communities in some rural areas, and heavy modern migration into Athens from across Greece.
Greek is the main language. Because Athens is a major capital and migration center, the Attica reference should be read as a regional central Greek profile rather than a perfect proxy for every Athenian family.
As a genetic reference, Greek Attica is useful for comparison with Laconia, Arcadia, southern Euboea, Samos, Phocis, Corinthia, Achaea, Arbëreshë, Argolis, and other central/southern Greek references.
In the World Genetics modern G25 comparison, the closest non-self match for Greek Attica is Greek Euboea South. Other nearby references include Greek Peloponnese Laconia, Greek Central Greece Phocis, Greek Central Greece Boeotia, and Greek Western Greece Aetolia-Acarnania. This gives the Greek Attica profile its nearest modern genetic context inside the current reference database.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Attic Greek is best interpreted as a central Greek profile, close to Laconia, Arcadia, southern Euboea, Samos, Phocis, Corinthia, Achaea, and Argolis.
The heatmap should emphasize Attica, Athens, Laconia, Arcadia, Euboea, Samos, Phocis, Corinthia, Achaea, and Argolis.
The closest non-self match in this World Genetics comparison is Greek Euboea South. Other nearby references include Greek Peloponnese Laconia, Greek Central Greece Phocis, Greek Central Greece Boeotia, and Greek Western Greece Aetolia-Acarnania.
In the current modern G25 reference set, Greek Euboea South is the closest listed match to the Greek Attica average after removing Greek Attica itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Greek Attica G25 average, giving the closest-match results a geographic view.
