The Census in India is conducted in two phases. The first phase known as House listing & Housing Census was conducted during April-September, 2010 and the Population Enumerations throughout the country were conducted between 9th February to 28th February, 2011 through State Governments/Union Territories Administrations.
Census taking in India is a very challenging task, in view of its multi-ethnic, multi-lingual, multi-cultural and multi-level society. The complexity of the exercise can be visualized from the fact that Census Schedules were canvassed in 16 languages and the training given in 18 languages. About 5.4 million Instruction manuals and 340 million Census Schedules were printed. 2.7 million Enumerators and Supervisors were engaged in the task of Census taking across 35 States, 640 districts, 5924 sub-districts, 7936 towns and 6.41 lakh villages. The task of these functionaries is quite strenuous and entails great responsibility. As such, the Census Operations depend heavily on the intelligence and diligence of various functionaries in States/UTs.
