Digital Census 2026: Challenges, NRI Representation and Data Accuracy

The 2026-2027 Census is India’s first fully digital census. It was delayed from 2021 due to COVID-19 and is critical because its data will form the basis for future delimitation (re-fixing of constituency boundaries).

• Process and Phases: The census involves two phases: House Listing followed by Population Enumeration.
• Counting Methodology: India uses an “Extended De-facto” method. This means a person is counted at their usual residence if they have stayed there for at least one day in the last 20 days, rather than strictly where they are found on the day of the census.
• The NRI Dilemma: Currently, Non-Resident Indians (NRIs) are often excluded from the census. This can lead to states like Kerala or Punjab losing parliamentary seats because a significant portion of their population (over 1.58 crore NRIs nationally) is not counted.
• Digital Challenges:
  • Technical Literacy: Many of the 30 lakh teachers conducting the census may struggle with the digital app, leading to manual paper entries that risk errors and privacy breaches.
  • Data Complexity: Overly complex manuals (e.g., a six-page manual for defining disability) often lead teachers to skip details, resulting in “garbage data”.
• Self-Enumeration Risks: Allowing citizens to fill their own data can lead to fraudulent entries or errors if they do not read the detailed instructions.

Conclusion

For the digital census to be effective, the government must ensure simple questions in local languages, robust field testing, and a mechanism to include the NRI population to ensure fair political representation.
