Context: The efficacy of the self-enumeration module for the first phase of Population Census 2027 will be tested from Saturday (November 1, 2025) with enumerators visiting the homes of prominent citizens in their areas and helping them fill the details on a website, a senior government official told The Hindu. This will be the first digital Census, and the first to enumerate caste in independent India.
What Is a Census?
A census is the official enumeration of the population, conducted periodically by the government. It provides critical data on the size, composition, socio-economic features, and geographical distribution of the population.
- India’s first Census was held in 1881 under British rule.
- Since then, it has been conducted every 10 years.
- The exercise includes demographic, cultural, and economic information of the entire population.
Why Is the Census Important?
Evidence-Based Policy Making: Census data provides a solid foundation for planning public health, education, housing, and employment schemes.
Electoral and Political Utility: Census data supports delimitation of parliamentary and assembly constituencies, and helps implement reservation policies (e.g., one-third women’s reservation).
Welfare Delivery and Budget Allocation: Data disaggregation helps ensure targeted benefits to SCs, STs, OBCs, minorities, senior citizens, and other vulnerable groups.
Demographic and Social Analysis: It captures fertility, mortality, migration, urbanization, ageing, and literacy patterns, critical to understanding human development.
Benchmark for Surveys: Surveys like NFHS, NSSO, etc., use census data as a benchmark for extrapolating trends. Without the census, these surveys lack accuracy.
Legal Provisions for Census in India
| Provision | Description |
|---|---|
| Entry 69, Union List | Empowers only the Central Government to conduct the Census. |
| Census Act, 1948 | Provides legal framework for conducting and managing the Census. |
| Registrar General and Census Commissioner | Authority under Ministry of Home Affairs responsible for execution. |
| No constitutional mandate | The Constitution does not mandate a fixed periodicity; it is governed by statute. |
Timeline and Status of India’s Upcoming Census
- Census 2021 postponed due to COVID-19.
- Next Census will be conducted in two phases:
- Oct 2026: For snow-bound regions (e.g., J&K, Himachal, Ladakh).
- March 2027: For rest of India.
- Data Release expected by end of 2027.
What Is the National Population Register (NPR)?
The NPR is a register of all “usual residents” (living in a locality for 6+ months) of India, created under the Citizenship Act, 1955.
- Managed by the Registrar General of India.
- Includes foreigners.
- Data from NPR feeds into National Register of Indian Citizens (NRIC/NRC).
NPR vs NRC: A Quick Comparison
| Feature | NPR | NRC |
|---|---|---|
| Who’s Included | All residents (incl. foreigners) | Only Indian citizens |
| Legal Basis | Citizenship Act, 1955 | Citizenship Act, 1955 |
| Purpose | Resident database | Verified citizenship registry |
| Status | Nationwide (except Assam) | Implemented only in Assam (so far) |
Census and Caste Enumeration
- The upcoming census will include caste and sub-caste data for the first time post-Independence.
- Past censuses recorded only SC/ST data.
- This enables:
- Better welfare budgeting.
- Assessment of access to schemes like PMAY, Skill India.
- Improved social justice indicators.
Innovations in the 2026–27 Census
- Digital data collection through mobile apps (in 16 languages).
- Self-enumeration option for citizens.
- Census Management & Monitoring System (CMMS) portal for real-time coordination.
- Faster compilation and analysis with GIS mapping and real-time dashboards.
Determinants of Population Change
| Factor | Indicators |
|---|---|
| Fertility | Crude Birth Rate, Total Fertility Rate, Son preference |
| Mortality | Crude Death Rate, Infant Mortality Rate (IMR), Maternal Mortality Rate (MMR), Life Expectancy |
| Migration | Immigration and Emigration |
Example:
- India’s IMR declined from 37/1000 (2015) to 30/1000 (2019).
- MMR improved from 8.1 (2015–17) to 7.3 (2016–18).
Factors Influencing Population Distribution in India
| Category | Examples |
|---|---|
| Geographical | Water availability (Doab), fertile soil (Ganga Plains), climate (Ladakh sparse) |
| Economic | Urbanization (Delhi NCR), industrial hubs (Mumbai, Jamshedpur) |
| Social & Cultural | Pilgrimage towns (Varanasi), areas of unrest (migration from Myanmar, Afghanistan) |
Role in Tracking Sustainable Development Goals (SDGs)

- SDG 1 (No Poverty)
- SDG 3 (Good Health and Well-being)
- SDG 4 (Quality Education)
- SDG 10 (Reduced Inequalities)
