Solution:The Fifth Schedule of the Constitution deals with the administration and control of Scheduled Areas as well as of Scheduled Tribes residing in any State other than the States of Assam, Meghalaya, Tripura and Mizoram.The Dhebar Commission (1960-61), laid down the following criteria for declaring any area as a 'Scheduled Area' under the Fifth Schedule: Preponderance of tribal population, which should not be less than 50 percent.
Compactness and reasonable size of the area. Underdeveloped nature of the area. Marked disparity in the economic standard of the people as compared to the neighboring Areas.
Later, a viable administrative entity, such as a district, block, or taluk, has been also identified as an important additional criterion. According to the Ministry of Tribal Affairs, these criteria are not spelt out in the Constitution of India but have become well established.
