Census operations throughout India are being postponed due to ongoing covid pandemic which is continuing for the second year. Restrictions under the pandemic were expected to have been relaxed to a very large extent but after the resurgent of another covid variant –omicron- all plans to return to normalcy has been shelved. The postponement of census operations was announced last year by the Registrar General of India (RGI) and Census Commissioner. The RGI had written to the states and union territories in December 2021, extending the date for making changes to administrative boundaries till end of June 2022. Originally, the field work of house-listing and housing Census, the first phase of Census 2021, along with the updating of National Population Register (NPR) was to be conducted in a period of 45 days during April 2020 to September 2020 in different states and territories, depending on their local conditions and other priorities. After the house-listing, the population enumeration was to be carried out between February 9 and 28 last year. The world’s decadal population growth shows that there is an increase of around eight crore people annually. For instance, in 2001 the global population was 6,222,626,606 and in 2011 it rose seven billion or 7,041,194,000. By 2021 it is estimated that the global population will increase to 7,874,965,825 billion. India recorded a total of 1,027,015,247 people in 2001 and by 2011 the number shot up to 1,210,854,977. The estimate for 2021 is expected to be 1,400,000,000. With regard to Nagaland, the census in 2001 was recorded at 19,90,036 and in 2011 it was-19,78,502 and as per the 2021 census, it is estimated to be 21,89,297 . The census between 2011 and 2021 shows an increase by 2,10,795 and which indicates that each year there were around 21,000 people added or around 1700 additions every month. It may be recalled that Nagaland’s decadal population growth between 1991 to 2001 was so inflated that it made it to the ignominious record books. As per the controversial census from 1991 and 2001, while the country’s decennial growth rate for 1991-2001 was 21.54%, Nagaland’s growth rate for the same period stood at 64.53 %, which was the highest in the country. The importance of proper census undertaken cannot be under stressed. As the state is passing through a crisis due to clamour for ILP and RIIN, census operations are very crucial indicators of the composition of people belonging to various communities both indigenous and non-indigenous. Census will also directly impact the process of readjustments of assembly constituencies. Delimitation was to have been effected in 2002 but the Constitution of India specifically amended (84th amendment) in 2002, not to have interstate delimitation of constituencies till 2026.Thus, the present constituencies carved out on the basis of the 2001 census shall continue to be in operation till 2026 and it will be done on the basis of population 2021. Like creation of new districts and demands for more districts or administrative headquarters, population density will be crucial factors to justify decisions. Census would also have impact on number of voters and in turn, also impact on delimitation or adjustments of assembly constituencies.
