Haplogroup H is typically found among Indo-Aryan, Dravidian and Tribal(Indian Tribals and Pakistani Kalash tribe) populations in the Indian subcontinent, with highest concentration in India]( West India and South India in particular) and Bangladesh. In Europe it is found almost exclusively among the Gypsies (Romani), who belong predominantly (between 15% and 50%) to the H1a (M82) subclade of Indian origin. The highest frequencies of haplogroup H among non-Romani Europeans are found in regions with large Romani populations, such as Romania, Slovakia, the southern Balkans, and Andalusia, suggesting that these lineages are also of Romani origin.
