Abstract: India is a country which is best known for its culture and tradition. Tribal groups are homogeneous, culturally firm and they wish to survive in their own style. Irular tribes of Tamil Nadu occupy the second largest groups of tribes after the Badgas. They are situated at the base of the western ghat. The road which takes us to the village is undeveloped and rocky. The huts are little developed into houses with cement sheet. Unlike the earlier tribal people, 21st century tribes have normal dress code like other people. The major occupation of these tribal people is field work as farmers. Neither hospital nor any other medical facility is available with in 15 Kms. There is a government school situated about three to four kilometers away from the village premises. When the girls attain their puberty, there will be seven days celebration at their houses. The marriage is not considered as an important custom of the villagers. Death is considered as an important ritual in this community. The irular tribes are mostly non vegetarians. It can be concluded that the tribal people of India need still more improvement in all walks of their lives.
