A focused population profile of Arunthathiyar, their Tamil Nadu and South Indian background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Arunthathiyar are a community primarily associated with Tamil Nadu and parts of South India. Like many South Asian caste and regional references, this page should be read as a population average rather than a complete description of every family or local subgroup.
Tamil is the main regional language, while Telugu, Kannada, and other South Indian languages may be relevant in some migration or borderland contexts.
As a genetic reference, Arunthathiyar is useful for comparison with Sakilli, Pallan, Bhil, Madiga Andhra Pradesh, Tamil Nadu Dalit, Uttar Pradeshi Chamar, Marathi, Sinhalese, Indian South, and North Kannadi.
In the World Genetics modern G25 comparison, the closest non-self match for Arunthathiyar is Telugu Mala Andhra Pradesh. Other nearby references include Chakkiliyan, Tamil Kuga Vellalar, Telugu Jew (Bene Ephraim), and Tamil Devendrakulathan. This gives the Arunthathiyar profile its nearest modern genetic context inside the current reference database.
