The Centre has asked states and Union Territories to make any proposed changes in the boundaries of administrative units before December 31, when they will be considered final for the census exercise.
In a letter to all states and Union Territories, Registrar General and Census Commissioner of India Mritunjay Kumar Narayan has said that for the Census, all villages and towns are divided into uniform enumeration blocks and for each block, an enumerator is assigned to avoid any miss or repetition during the population count.
According to norms, the Census can be conducted only three months after the freezing of boundary limits of administrative units such as districts, sub-districts, tehsils, talukas and police stations. PTI
