A focused population profile of Bangladesh Bengalis, their eastern South Asian background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Bangladesh Bengalis are the majority population of Bangladesh, part of the wider Bengali-speaking world of the Bengal delta. Bangladesh includes regional histories tied to Dhaka, Chittagong, Sylhet, Rajshahi, Khulna, Barisal, Brahmanbaria, and southeastern Bengal.
Bengali, or Bangla, is an Indo-Aryan language and the national language of Bangladesh. It has regional dialects and deep literary, religious, musical, and political importance in Bengali identity.
As a genetic reference, Bengali Bangladesh should be read as an eastern South Asian profile with both South Asian and East/Southeast Asian-adjacent signals relative to many western and northern South Asian groups.
In the World Genetics modern G25 comparison, the closest non-self match for Bengali Bangladesh is Bengali. Other nearby references include Bengali Bangladesh Sylhet, Bengali Bangladesh Southeast, Bengali Bangladesh Brahmanbaria, and Kumaoni Scheduled Caste. This gives the Bengali Bangladesh profile its nearest modern genetic context inside the current reference database.

The ancestry model gives deeper component proportions, while closest matches show modern similarity. Bengali Bangladesh results are best interpreted as eastern South Asian, with the closest references concentrated in Bangladesh and Bengal.
The heatmap should emphasize Bangladesh, West Bengal, eastern India, and nearby Bengal-region references.
The closest non-self match in this World Genetics comparison is Bengali. Other nearby references include Bengali Bangladesh Sylhet, Bengali Bangladesh Southeast, Bengali Bangladesh Brahmanbaria, and Kumaoni Scheduled Caste.
In the current modern G25 reference set, Bengali is the closest listed match to the Bengali Bangladesh average after removing Bengali Bangladesh itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Bengali Bangladesh G25 average, giving the closest-match results a geographic view.
