Administrative structure of India

In India, a Community development block (CD block) or simply Block is a sub-division of Tehsil, administratively earmarked for planning and development.[1] In tribal areas, similar sub-divisions are called tribal development blocks (TD blocks).[2] The area is administered by a Block Development Officer (BDO), supported by several technical specialists and village-level workers.[3] A community development block covers several gram panchayats, the local administrative units at the village level. A block is a rural subdivision and typically smaller than a tehsil. A tehsil is purely for revenue administration, whereas a block is for rural development purposes. In most states, a block is coterminous with the panchayat samiti area.[4][5][6]


The nomenclature varies from state to state, such as common terms like "block" and others including community development block, panchayat union block, panchayat block, panchayat samiti block, development block, etc. All denote a CD Block, which is a subdivision of a district, exclusively for rural development.[7][6][4]


The concept of the community development block was first suggested by Grow More Food (GMF) Enquiry Committee in 1952 to address the challenge of multiple rural development agencies working without a sense of common objectives.[8] Based on the committee's recommendations, the community development programme was launched on a pilot basis in 1952 to provide for a substantial increase in the country's agricultural programme, and for improvements in systems of communication, in rural health and hygiene, and in rural education and also to initiate and direct a process of integrated culture change aimed at transforming the social and economic life of villagers.[9] The community development programme was rapidly implemented. In 1956, by the end of the first five-year plan period, there were 248 blocks, covering around a fifth of the population in the country. By the end the second five-year plan period, there were 3,000 blocks covering 70 per cent of the rural population. By 1964, the entire country was covered.[10]

Block Development Officer

In India, a Civil service officer of the rank of Block Development Officer (BDO) is the in-charge of a CD Block in India. BDO are usually officers of representative state-governments. BDO reports to the Sub Divisional Magistrate (SDM).
