Census 2027 – Phase II Overview
The second phase of the Census 2027 will begin door‑to‑door enumeration on 1 December in Uttar Pradesh, Uttarakhand, Goa and Punjab, and on 25 January 2027 for the rest of the country. This phase, called Population Enumeration, is markedly different from the first phase (House‑Listing Operations) because it asks many sensitive and new questions.
Key Developments
- 34 lakh enumerators, mainly government school teachers, will be deployed; private teachers and members of NGOs are now also eligible.
- Enumerators will use a mobile app for data capture – India’s first fully digital census.
- The training pyramid starts with National Trainers, then Master Trainers, Field Trainers and finally enumerators, with mandatory hands‑on practice of the app.
- A new PRAMAN framework will be embedded in all training modules.
- 13 new questions are added, including parents’ religion and place of birth, Aadhaar and other identity numbers, digital literacy, and detailed caste information.
Important Facts
Each enumeration block covers about 750‑800 people. Enumerators must spend 20‑25 minutes per household because of the expanded questionnaire. The most sensitive additions are:
- Aadhaar number (Q 37). Respondents can refuse; the question is optional.
- Caste name (Q 10C). Apart from SC/ST, respondents must type their caste; there is no drop‑down list for OBC or other categories.
- Parents’ religion, mother‑tongue, and village‑level place of birth.
- Bank‑account, passport, driving‑license, mobile and voter‑ID numbers, if available.
Exam Relevance
Understanding the Census process is vital for GS 1 (Demography) as it provides the primary data source for population trends, migration, fertility, and socio‑economic indicators. The role of the Registrar General of India and the emphasis on gender‑sensitisation tie into GS 2 (Polity) and GS 4 (Ethics). The digital shift and the PRAMAN model illustrate the use of technology and citizen‑centric governance, linking to GS 3 (Economy & Technology). Finally, the inclusion of caste data for the first time raises questions about social equity and data‑driven policy, relevant to both GS 1 and GS 4.
Way Forward
For aspirants, focus on:
- Memorising the new questionnaire structure and the rationale behind each sensitive question.
- Analyzing how accurate Census data influences planning in health, education, and employment sectors.
- Evaluating the challenges of digital data collection in a diverse country and the safeguards (confidentiality, optionality) built into the process.
- Connecting the PRAMAN framework to broader government‑citizen interaction models.
Keeping abreast of training updates and field reports will help answer UPSC questions on data‑driven governance, demographic policy, and the ethical dimensions of large‑scale surveys.
