According to the 2001 census the scheduled tribal population is 651,000 therefore representing 1.04% of the population.
Approximately 32% of the tribal population of the Nilgiri District live in the Pandalur taluk, and 14.33% live in the Gudalur taluk - the two key taluks in which CTRD works.
The target tribal beneficiaries of CTRD are the Kattunayakans, the Paniyans and the Kurumbas.
The majority of tribes live in often remote and geographically inaccessible hilly or forested areas, which tend to be under developed and poorly integrated with mainstream society.
