How is the allocation of funds decided for the tribal areas mentioned in this text?
The allocation of funds for the tribal areas mentioned in this text is decided by considering two factors: (1) the average excess of expenditure over revenues during the two years immediately preceding the commencement of this Constitution in respect of the administration of these areas, and (2) the costs of such schemes of development as may be undertaken by the State with the approval of the Government of India for raising the level of administration of the said areas to that of the rest of the State. Additionally, after the formation of an autonomous State under Article 244A, the President can specify how funds should be allocated between the State of Assam and the autonomous State if it comprises only some of the tribal areas referred to in the text.
