What Happened
- A resident of Pasighat in East Siang district, Arunachal Pradesh, flagged that the self-enumeration map on the official Census 2027 portal (se.census.gov.in) was displaying his hometown under the label "Medog" — a town in China located across the Line of Actual Control (LAC).
- The error appeared in the address confirmation field during the digital self-enumeration exercise, which requires residents to verify their location on an integrated map interface.
- The Registrar General of India (RGI) acknowledged the issue via its official social media handle and stated it had been escalated to the third-party map services provider; the error was rectified within hours.

Census of India — Constitutional and Administrative Framework
The Census of India is conducted under the Census Act, 1948, with the Registrar General and Census Commissioner of India (under the Ministry of Home Affairs) serving as the nodal authority. Census 2021, delayed due to COVID-19, was rescheduled to 2027. The upcoming census is India's first fully digital census, with self-enumeration (SE) forming a key phase where residents fill in their own household data via an online portal, verifying their address through an integrated map layer.
- Census Act, 1948 provides the legal basis; decennial census is administratively mandated (not constitutionally).
- Census 2027 will be the first to use digital self-enumeration at scale; over 5.72 lakh households had already completed SE by early April 2026.
- The portal at se.census.gov.in uses a third-party map service for address verification, creating a dependency on commercial geospatial data accuracy.
Connection to this news: The map interface error — displaying an Indian town with a Chinese placename — directly compromised the data integrity of the self-enumeration process and raised questions about the government's oversight of third-party geospatial services used in critical national exercises.
China's Systematic Renaming of Arunachal Pradesh Locations
China has repeatedly published "standardised" Chinese names for locations in Arunachal Pradesh as part of its assertion that the state is "Zangnan" (South Tibet/southern Tibet). China rejects the McMahon Line — demarcated at the 1914 Shimla Convention between British India and Tibet — arguing that Tibet lacked sovereign authority to enter such an agreement. India administers all 83,743 sq km of Arunachal Pradesh and categorically rejects these renaming exercises. As recently as April 10, 2026, China published its sixth such list of "standardised" names covering 23 passes, peaks, rivers, and settlements in Arunachal Pradesh.
- The McMahon Line forms the de facto border between Arunachal Pradesh and China's Tibet Autonomous Region.
- "Medog" (Chinese: 墨脱) is a county in China's Tibet Autonomous Region situated north/beyond the LAC — distinct from Pasighat, which lies well within Indian territory.
- China has published renaming lists in 2017, 2021, 2023, 2024, 2025, and April 2026.
Connection to this news: The inadvertent display of "Medog" — a Chinese geographic label — overlaid on Pasighat in a Government of India portal, even if a technical glitch, illustrates the risks of using third-party maps not calibrated to India's official boundary depictions, and it coincided with renewed Chinese renaming activity just days earlier.
MapmyIndia and India's Indigenous Geospatial Data Policy
India's Geospatial Data Guidelines (2021) liberalised mapping regulations and encouraged the use of domestic map providers. MapmyIndia (CE Info Systems) is India's primary indigenous mapping company and is licensed to provide government-approved map data. In the context of the Census 2027 portal incident, MapmyIndia publicly offered its services as an alternative to address the boundary depiction concerns.
- The 2021 Geospatial Data Guidelines removed licensing restrictions on Indian entities and encouraged Indian-origin geospatial data.
- Government portals dealing with border areas are required to use maps consistent with the Survey of India's official depiction.
- Survey of India (under Ministry of Science and Technology) is the apex national surveying authority.
Connection to this news: The incident highlighted a governance gap — the RGI's portal relied on a commercial map provider whose boundary data did not align with India's official position, underscoring the need for critical government platforms to use domestically certified map services.
