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.
