Sample Registration System
- The SRS is a demographic survey for providing reliable annual estimates of infant mortality rate, birth rate, death rate and other fertility and mortality indicators at the national and sub-national levels.
- It was initiated on a pilot basis by the Registrar General of India in a few states in 1964-65, it became fully operational during 1969-70.
- The field investigation consists of continuous enumeration of births and deaths in selected sample units by resident part time enumerators, generally anganwadi workers & teachers, and an independent survey every six months by SRS supervisors. The data obtained by these two independent functionaries are matched.
Registrar General of India
- Registrar General of India was founded in 1961 by the Government of India under the Ministry of Home Affairs.
- It arranges, conducts and analyses the results of the demographic surveys of India including Census of India and Linguistic Survey of India.
