The Census of India 2027 marks an important milestone in the country’s demographic history. It will be India’s 16th Census overall and the 8th Census since Independence.
The upcoming census is particularly significant because the 2021 Census could not be conducted as scheduled due to the COVID-19 pandemic. The 2027 exercise also introduces major technological changes, including digital data collection and self-enumeration, while incorporating caste enumeration.
Which Census Is the 2027 Census of India?
The Census 2027 is the 16th Census of India and the 8th Census after Independence.
India’s first census exercise was conducted in 1872, although it was not carried out simultaneously across the entire country. The first synchronous census took place in 1881. Since then, census operations have generally been conducted every ten years.
The 2027 Census will be conducted under the Census Act, 1948, by the Office of the Registrar General and Census Commissioner, India, under the Ministry of Home Affairs.
The exercise will be conducted in two broad phases:
- Phase 1 – Houselisting and Housing Census: This phase focuses on collecting information about houses, housing conditions and household facilities.
- Phase 2 – Population Enumeration: This phase records demographic, social and economic information about the population.

Census During the British Era: 1872 to 1941
1872: First Census Exercise
The 1872 census was the first major attempt to collect population information systematically across different parts of India. However, it was not a synchronous, all-India census because enumeration took place at different times in different regions.
1881: First Synchronous Census
The 1881 Census was a major turning point. It was the first synchronous census of India, with enumeration carried out simultaneously across the country.
From this point, census operations developed into a more regular decennial exercise.
1891 to 1931: Expansion of Census Data
Over the following decades, census operations became increasingly detailed. Information relating to religion, language, literacy, occupation, migration and other demographic characteristics was collected.
The 1931 Census is particularly important in India’s census history because it was the last census conducted under British rule to provide detailed caste-related information.
1941: Census During World War II
The 1941 Census was conducted during the Second World War. Wartime conditions affected the processing and publication of some census information.
Post-Independence Census: 1951 to 2011
1951 Census: First Census of Independent India
The 1951 Census was the first population census conducted after India became independent. It recorded a population of approximately 36.1 crore.
It was an important administrative exercise for a newly independent country dealing with the aftermath of Partition and major demographic changes.
1961 Census
The 1961 Census expanded the scope of demographic data collection. Greater attention was given to employment, migration and economic characteristics.
1971 Census
The 1971 Census introduced questions related to fertility patterns among currently married women, adding greater depth to population studies.
1981 Census
The 1981 Census further expanded information on migration and socio-economic characteristics, helping policymakers understand changing population patterns.
1991 Census
The 1991 Census followed a more standardized approach to literacy, with literacy being considered for people aged 7 years and above.
2001 Census
The 2001 Census marked an important technological shift. Digital technologies, including Intelligent Character Recognition (ICR), were used to process census forms and improve data handling.
2011 Census
The 2011 Census was the 15th Census of India and the last completed population census before the upcoming 2027 exercise.
India’s population was recorded at more than 121 crore. The census also involved the house-listing exercise associated with the National Population Register (NPR).
Why Is Census 2027 Important?
Census 2027 is significant not only because it follows a long gap after the 2011 Census but also because of its technological and methodological changes.
1. India’s First Digital Census
The 2027 exercise is designed around a digital framework, with mobile applications and digital systems being used to support field-level data collection and monitoring.
2. Self-Enumeration Facility
One of the major changes is the introduction of self-enumeration, allowing eligible residents to provide certain information through an online system before field verification.
This is expected to make the census process more technology-driven and accessible.
3. Caste Enumeration
Census 2027 also includes caste enumeration, making it particularly significant from a demographic and policy perspective.
The last census conducted in British India that included detailed caste data was the 1931 Census.
4. Two-Phase Census Exercise
The census will be carried out through two major stages:
Phase 1: Houselisting and Housing Census
Phase 2: Population Enumeration
Together, these phases will provide updated information about India’s population, households and socio-economic characteristics.
