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, Arunthathiyar is closest to Sakilli, Pallan, Bhil, Madiga Andhra Pradesh, Tamil Nadu Dalit, Uttar Pradeshi Chamar, Marathi, Sinhalese, Indian South, and North Kannadi. The result places Arunthathiyar in a South Indian and broader Indian caste/community comparison space.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Arunthathiyar is best interpreted as a Tamil/South Indian profile, close to neighboring South Indian Dalit, caste, regional, and broader Indian references. The small sample size means it should be interpreted carefully.
The heatmap should emphasize Tamil Nadu, Andhra Pradesh, Karnataka, Maharashtra, broader South India, northern Indian caste references, Sri Lanka, and the Indian subcontinent.

Several South Asian caste/community references can overlap in G25 space, including Dalit and regional Indian profiles.
