A district of an Indian state is an administrative geographical unit, headed by the Deputy Commissioner (DC), which combines the offices of the District Magistrate ultimately responsible for maintaining law and order and is also responsible for collection of the revenue. Generally, an officer belonging to the Indian Administrative Service becomes the DC but occasionally officers belonging to the State Civil Service ( like ACS) too get appointed. The DC is assisted by a number of officials belonging to different wings of the administrative services of the state.
Assam is divided into 33 administrative geographical units of districts, which are further divided into 78 subdivisions, which are the administrative units. Assam has 155 Tehsils, which represent revenue collecting units under a district administration, and both are treated as sub–districts.
