India's First Digital Census Preparations

Summary of Digital Census 2027 in India

Constitutional and Legal Context:

• The Census is governed under the Census Act, 1948.
• The first census after 2026 can be utilized to redraw Lok Sabha constituencies, as mandated by the Constitution.
• The next general elections are anticipated in 2029.

Census Schedule:

• The final enumeration will occur between April 1, 2026 and February 28, 2027.
• The Government officially notified the intent to conduct the Census on June 16, 2025.
• The previous Census was conducted in 2011.

Pre-test Phase:

• A two-phase pre-test is currently being conducted, known as House Listing and Housing Operation (HLO).
• The first phase is ongoing from November 10-30 across all States and Union Territories.
• A window for self-enumeration occurred from November 1-7.

Methodology and Execution:

• Data collection includes geotagging homes and conducting a survey with 35 questions regarding household amenities, construction materials, drinking water sources, etc.
• The enumeration blocks are finalized, with approximately 24 lakh blocks anticipated, each consisting of 150-180 houses or 650-800 people.

Technological Incorporation:

• The Census utilizes two applications: Digital Layout Map (DLM) for geotagging and Census 2027-Houselist for data input.
• The DLM app requires real-time presence at the geotagged location to ensure data accuracy.

Demographic Representation:

• Government officials engaged in the census exercise, primarily teachers and women, to facilitate easier communication with households.
• Enumerators’ training was conducted to familiarize them with the digital interface and the questions posed.

Judicial and Legislative Background:

• In a 2021 affidavit to the Supreme Court, the Union government criticized the 2011 data from the Socio Economic and Caste Census (SECC), citing inaccuracies that affect reservations based on caste.

Financial Aspects:

• Enumerators receive an honorarium of ₹10,000 for participating in the pre-test.

Challenges in Caste Enumeration:

• Methodology for enumerating Other Backward Classes (OBCs) remains under debate. The last comprehensive caste count was in the 1931 Census.

Community Engagement:

• Training programs and help desks are set up to assist enumerators, enhancing understanding of the digital census operation.

Public Awareness:

• Though the Census exercise is primarily official, community members showed varying degrees of awareness regarding its purpose, with some mistaking it for voter registration.

This pre-test exercise is pivotal in ensuring the success of India’s first digital Census, anticipated to adapt to modern data collection technologies and address historical complexities of census data enumeration.
