A focused population profile of Sri Lankan Tamils, their island South Asian background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Sri Lankan Tamils are a Tamil-speaking population of Sri Lanka, especially associated with the Northern and Eastern provinces, Jaffna, Trincomalee, Batticaloa, and diaspora communities worldwide. They are distinct from, but related to, Tamil-speaking populations in South India.
Tamil is a Dravidian language with a long literary history and major communities in both Sri Lanka and Tamil Nadu. Sri Lankan Tamil varieties have their own regional features and community histories.
As a genetic reference, Tamil Sri Lanka should be compared with Sri Lankan, Sinhalese, Telugu, South Indian, and Tamil or Dravidian-speaking references.
In the World Genetics modern G25 table, Tamil Sri Lanka is closest to Sri Lankan, Sinhalese, Telugu, Telugu Yadav, Indian South, Piramalai Kallar, Marathi, and Telugu Balija. The profile sits in a Sri Lankan and South Indian comparison space, with island references and Telugu/South Indian references close.
