There are hundreds of tribes in India. Most of the tribes are Scheduled under constitutional provisions. That is why they are called Scheduled Tribes of India or more commonly STs. India is the second largest country in the world on the basis of tribal population, the first being South Africa. It is worth mentioning here that the Constitution of India does not define Scheduled Tribes as such. Article 366(25) refers to scheduled tribes as those communities who are scheduled in accordance with Article 342 of the Constitution. According to Article 342 of the Constitution, the Scheduled Tribes are the tribes or tribal communities or part of or groups within these tribes and tribal communities which have been declared as such by the President through a public notification. As per the 1991 Census, the Scheduled Tribes account for 67.76 million representing 8.08 percent of the country's population. Scheduled Tribes are spread across the country mainly in forest and hilly regions. The 1991 Census figures reveal that 42.02 percent of the Scheduled Tribes populations were main workers of whom 54.50 percent were cultivators and 32.69 per cent agricultural laborers. Thus, about 87 percent of the main workers from these communities were engaged in primary sector activities. The literacy rate of Scheduled Tribes is around 29.60 percent, as against the national average of 52 percent. More than three-quarters of Scheduled Tribes women are illiterate. These disparities are compounded by higher dropout rates in formal education resulting in disproportionately low representation in higher education. Not surprisingly, the cumulative effect has been that the proportion of Scheduled Tribes below the poverty line is substantially higher than the national average. The estimate of poverty made by Planning Commission for the year 1993-94 shows that 51.92 percent rural and 41.4 percent urban Scheduled Tribes were still living below the poverty line. The Constitution of India incorporates several special provisions for the promotion of educational and economic interest of Scheduled Tribes and their protection from social injustice and all forms of exploitation. These objectives are sought to be achieved through a strategy known as the Tribal Sub-Plan strategy, which was adopted at the beginning of the Fifth Five Year Plan. The strategy seeks to ensure adequate flow of funds for tribal development form the State Plan allocations, schemes/programmes of Central Ministries/Departments, financial and Developmental Institutions. The cornerstone of this strategy has been to ensure earmarking of funds for TSP by States/UTs in proportion to the ST population in those State/Uts. Besides the efforts of the States/UTs and the Central Ministries/Departments to formulate and implement Tribal Sub-Plan for achieving socio-economic development of STs, the Ministry of Tribal Affairs is implementing several schemes and programmes for the benefits of STs. There are now 194 Integrated Tribal Development Projects (ITDPs) in the country, where the ST population is more than 50% of the total population of the blocks or groups of block. During the Sixth Plan, pockets outside ITDP areas, having a total population of 10,000 with at least 5,000 scheduled tribes were covered under the Tribal Sub-Plan under Modified Area Development Approach (MADA). So far 252 MADA pockets have been identified in the country. In addition, 79 clusters with a total population of 5,000 of which 50 per cent are schedule tribes have been identified. In order to give more focussed attention to the development of Scheduled Tribes, a separate Ministry, known as the Ministry of Tribal Affairs was constituted in October 1999. The new Ministry carved out of the Ministry of Social Justice and Empowerment, is the nodal Ministry for overall policy, planning and coordination of programmes and schemes for the development of Scheduled Tribes. __Tribal communities in India__ ((Kota tribe))
