Tribals in Kerala are the indigenous population found in the southern Indian state of Kerala. Most of the tribal people of Kerala live in the forests and mountains of Western Ghats, bordering Karnataka and Tamil Nadu. Tribal people groups who are food-gatherers (without any habit of agricultural practice), with diminishing population and very low or little literacy rates can be called as Primitive Tribes. Cholanaikkans, Kurumbas, Kattunaikans, Kadars and Koragas are the five primitive tribal groups in Kerala. Cholanaikkans can be said as the most primitive of them and found only in the Malappuram District. Only a handful of families are living in the Mancheri hills of Nilambur forest division. Kattunaikans, another lower-hill community related to Cholanaikkans, are mainly seen in Wayanad district and some in Malappuram and Kozhikode districts. Kadar population is found in Trisur and Palakkad districts. Kurumbas are living in the Attappady Block of Palakkad district. The Koraga habitat is in the plain areas of Kasaragod district.
