Jāti (in Devanagari: जाति) (the word literally means thus born) is the term used to denote communities and sub-communities in India. It is a term used across religions. In Indian society each jāti typically has an association with a traditional job function or tribe, although religious beliefs (e.g. Sri Vaishnavism or Veera Shaivism) or linguistic groupings define some jatis. A person's surname typically reflects a community (jati) association: thus Gandhi = perfume seller, Dhobi = washerman, Srivastava = military scribe, etc. In any given location in India 500 or more jatis may co-exist, although the exact composition will differ from district to district.
