Kolkata: For enumerators heading to remote villages, forest settlements and other areas where mobile connectivity remains patchy, a disappearing network signal will not hamper the field work. An app has been designed with an offline facility, allowing field staff to fill in the 33-question household schedule even without an internet connection.“The feature on the Houselisting Operations (HLO) mobile app is crucial as Census will be India’s first fully digital population census, with enumerators using mobile devices instead of paper schedules. The application allows data to be entered and stored on the device while offline and synchronised with the central system once connectivity is restored,” said Nikhil Pawan Kalyan, the Bengal Census director.Officials explained this means an enumerator can continue visiting households in a no-network zone, complete the required questions and upload the information later after reaching an area with internet access. The arrangement is expected to be particularly useful in hilly, forested, island and other geographically difficult areas where uninterrupted mobile connectivity cannot be guaranteed.The HLO questionnaire covers 33 questions relating to housing conditions and household amenities. It seeks details such as the type and use of the dwelling, construction material, number of rooms, ownership status, drinking water, toilet facilities, electricity and cooking fuel, besides household assets and internet availability.Govt has retained paper as a contingency option only in unavoidable circumstances. Such information will subsequently have to be digitised.The offline capability is part of a wider digital architecture being deployed for Census 2027, which includes the HLO app, a self-enumeration facility, digital mapping tools and a central monitoring system. The objective is to reduce paperwork, speed up data processing and ensure that connectivity gaps do not translate into gaps in enumeration.
