1. Census of India
It includes every element of the population and covers every individual unit in the entire population. It is carried out every 10 years and is published by the Registrar General and Census Commissioner of India. These surveys are done for getting information on the size, growth rate, and distribution of population, population projections, density of population, gender composition of the population, and state of literacy.
All this information is required to understand many economic and social issues in India and according to this plans and policies are formulated.
2. National Sample Survey Office (NSSO)
NSSO is a government organization under the ministry of statistics and program implementation. This organization conducts regular surveys to collect sample surveys to collect basic statistical information relating to a variety of economic activity in rural and urban parts of the country.
For example, the 74th round of the NSSO survey was on the “Establishment focussed survey on the service sector”.
