The 2027 Census house listing phase is underway in some states, with questionnaire pre-testing conducted last year.
A question on caste is being included in the Census for the first time since Independence.
The 2027 Census data will be used for the next delimitation of Lok Sabha and State Legislative Assembly constituencies.
The Indian Census follows an extended de facto method of enumeration.
The entire data collection process for the next Census is planned to be carried out using mobile electronic devices.
There will be an option for respondents to self-enumerate using a computer or smartphone.
Detailed Insights:
The inclusion of a question on caste aims to provide comprehensive data, but experiences from surveys in Bihar and Karnataka suggest potential acceptance issues with the results.
The extended de facto method counts people at their usual residence, including those temporarily absent, and defines a household as members sharing a common kitchen.
Discrepancies exist between census data and voter lists due to the six-month residency requirement for voter registration and the inclusion of NRIs in voter lists but not in the census.
Some states with significant NRI populations, like Kerala, Gujarat, Punjab, Telangana, and Tamil Nadu, may experience a loss of Lok Sabha seats due to NRI exclusion from census data.
The use of mobile electronic devices for data collection can improve data quality and processing speed, but requires addressing challenges related to enumerator proficiency and data-entry errors.
Self-enumeration poses risks of respondent fatigue, inaccurate answers, and omission of certain individuals, necessitating well-worded questions and clear explanations.
Measures to improve accuracy include specific questions about the presence of individuals and relatives, but vigilance is needed to prevent fraudulent enumerations.
Key Concepts Involved:
De jure Census: Counting people at their place of legal residence.
De facto Census: Counting people at the place where they are present during the Census.
Delimitation: The process of redrawing the boundaries of parliamentary or assembly constituencies.
