A focused population profile of Bulgarians, their eastern Balkan background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Bulgarians are a South Slavic population native to Bulgaria in the eastern Balkans, between the Danube, the Black Sea, the Balkan Mountains, Thrace, and Macedonia. Bulgarian history includes Slavic, Bulgar, Byzantine, Ottoman, and Balkan layers.
Bulgarian is a South Slavic language written in Cyrillic and closely related to Macedonian. It has distinct grammatical features compared with many other Slavic languages and has been shaped by Balkan linguistic contact.
As a genetic reference, Bulgarian should be read in an eastern Balkan context. It is useful for comparison with Pomaks, Romanians, Gagauz, Macedonians, Serbs, Bosniaks, and neighboring Balkan references.
In the World Genetics modern G25 comparison, the closest non-self match for Bulgarian is Pomak Bulgaria. Other nearby references include Moldovan Ștefan Vodă, Bulgarian Sofia, Bulgarian Greece, and Pomak Greece. This gives the Bulgarian profile its nearest modern genetic context inside the current reference database.

The ancestry model gives deep component proportions, while the closest matches show modern similarity. Bulgarian results are best interpreted in a Balkan context, with Pomak, Romanian, Moldovan, Macedonian, Gagauz, and South Slavic references nearby.
The heatmap should emphasize Bulgaria, the eastern Balkans, Romania, North Macedonia, northern Greece, and nearby South Slavic or Balkan reference zones.
The closest non-self match in this World Genetics comparison is Pomak Bulgaria. Other nearby references include Moldovan Ștefan Vodă, Bulgarian Sofia, Bulgarian Greece, and Pomak Greece.
In the current modern G25 reference set, Pomak Bulgaria is the closest listed match to the Bulgarian average after removing Bulgarian itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Bulgarian G25 average, giving the closest-match results a geographic view.
