A focused population profile of Sylheti Bengalis from Bangladesh, their northeastern Bengal background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Sylheti Bengalis are Bengali-region communities from Sylhet and the surrounding Surma-Barak cultural zone of northeastern Bangladesh.
Sylheti is widely spoken alongside Bengali and Standard Bengali. Sylheti identity is especially visible in the United Kingdom and other diaspora communities, but this page focuses on the Bangladesh reference.
As a genetic reference, Bengali Bangladesh Sylhet is useful for comparison with Bengali Bangladesh Southeast, Bengali, Bengali Bangladesh, Bengali Bangladesh Brahmanbaria, Bengali India, Odia Khandayat, Garhwali Rajput, Indo-Trinidadian, Kapu, and Chenchu.
In the World Genetics modern G25 comparison, Bengali Bangladesh Sylhet is closest to Bengali Bangladesh Southeast, Bengali, Bengali Bangladesh, Bengali Bangladesh Brahmanbaria, Bengali India, Odia Khandayat, Garhwali Rajput, Indo-Trinidadian, Kapu, and Chenchu. The result places Sylheti Bengalis closest to other eastern and Bangladesh Bengali references.
| Population | Distance |

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Sylheti Bengali ancestry is best interpreted as northeastern/eastern Bengali, with close links to southeastern Bangladesh, Brahmanbaria, broader Bengali Bangladesh, and Bengali India references.
The heatmap should emphasize Sylhet, northeastern Bangladesh, the Surma-Barak region, southeastern Bangladesh, the wider Bengal Delta, northeastern India, and Bengali diaspora-linked comparison zones.
Yes. Sylheti Bengalis cluster closely with Bengali, Bengali Bangladesh, and other regional Bengali references.
Yes. Bengali Bangladesh Southeast is the closest match in this comparison.
Sylhet has a distinct regional language and diaspora history, but genetically this profile remains close to other eastern Bengali references.
