India’s Digital Census 2027: What To Expect From The Smartphone-Based Process
Share this article:
India’s Census 2027 will mark a historic shift as the country’s first fully digital census , with approximately 34 lakh enumerators using their own smartphones and a dedicated mobile application to collect data. Developed initially for the 2021 Census, the app, available in English and regional languages, is being upgraded to align with modern mobile technology. The census will include geo-tagging of buildings, caste enumeration, and a self-enumeration option, ensuring faster and more efficient data collection. This article explores the key features, phases, and innovations of Census 2027.
What is New in Census 2027?
A Paperless and Timely Process
The most notable benefit of this digital approach is the elimination of paper-based data collection. As an official source explained, if an enumerator has to collect data on paper for any reason, they will then be required to manually enter it on a dedicated web portal. This means there will be no need for subsequent scanning or data entry. According to a source, "This means that the Census data will, for the first time, be digitised at the enumerator level itself, ensuring timely availability of the information." This real-time data collection will significantly reduce the time lag typically associated with manual data entry and processing. The RGI , which operates under the Union Ministry of Home Affairs, is also developing a website for real-time monitoring and management of the entire exercise, ensuring the smooth execution of the process.
Two Phases of Census 2027
Census 2027 will be conducted in two distinct phases, as per The Indian Express:
Census 2027 is not just a data-collection exercise; it is a step towards modernising India’s statistical framework. The digital approach will:
Challenges and Considerations
While the digital census promises efficiency, challenges remain:
Digital Divide: Not all enumerators may have access to high-quality smartphones or stable internet connectivity, especially in rural areas.
Training Needs: Enumerators will require training to use the mobile app and web portal effectively.
Data Security: Safeguarding sensitive demographic data during transmission to the central server will be critical.
What is New in Census 2027?
- Smartphone-Based Data Collection: Enumerators will use their own Android or iOS devices to collect and upload data via a mobile app.
- Multi-Lingual App: The app will be available in English and regional languages, ensuring accessibility across diverse regions.
- Geo-Tagging of Buildings: For the first time, all residential and non-residential buildings will be geo-tagged using Digital Layout Mapping (DLM).
- Self-Enumeration Option: Citizens can input their data directly through a dedicated web portal.
- Caste Enumeration: The census will include data on the castes of household members, a significant addition to demographic records.

Two Phases of Census 2027
Census 2027 will be conducted in two distinct phases, as per The Indian Express:
- Houselisting Operation (April to September 2026): This phase will collect data on housing conditions, household amenities, and assets owned by households. Enumerators will also geo-tag all buildings using Digital Layout Mapping (DLM) to assign unique latitude-longitude coordinates on a Geographical Information System (GIS) map.
- Population Enumeration (February 2027): The population count will begin across India, except in Ladakh, Jammu & Kashmir, Himachal Pradesh, and Uttarakhand, where it will take place in September 2026 due to climatic conditions.
Why Census 2027 Matters
Census 2027 is not just a data-collection exercise; it is a step towards modernising India’s statistical framework. The digital approach will:
- Enhance Efficiency: Real-time data transfer and digitisation at the enumerator level will reduce processing time.
- Improve Accuracy: Geo-tagging and digital entry minimise errors associated with manual processes.
- Empower Citizens: The self-enumeration option allows individuals to contribute directly to the census.
- Support Policy-Making: Detailed data on castes, housing, and assets will aid in crafting targeted welfare schemes.
