Apart from the rural and urban local self governments, there is administrative machinery in every district. In every district, there are Sub-Divisions and Blocks or Talukas and the officials posted there assist the district administration.
District Magistrate is in-charge of the whole district administration. This post is also named as Deputy Commissioner, District Collector or Upayukta. He or She belongs to the Indian Administrative Service (IAS). District administration is responsible to implement the policies and programmes of the State and Central governments.
For better administration, each district is divided into smaller units called Sub Divisions. An officer called the Sub Divisional Officer (SDO) is made in-charge of this unit. The SDO is there to assist the District Magistrate in the field of administration and also works as his or her representative. The SDO belongs to the Indian Administrative Service (IAS) or to the cadre of State Civil Service.
The Block is the unit of administration at the lowest level. The officer in-charge of the Block is called Block Development Officer (BDO). He or She belongs to State Civil Service cadre and looks after various activities of the Block. The BDO is linked with the middle tier of Panchayati Raj as he or she is the ex-officio Secretary of the Panchayat Samiti and keeps the record of the meetings, prepares budget and coordinates various developmental activities.
