India is carrying out its first fully digital census, a major change in how it collects population data. Instead of paper forms, the process now uses online and digital tools to gather information. This is especially important because India has the world’s largest population, and the results will affect government funding, services, and political representation. At the same time, the move has raised concerns about privacy, data accuracy, and how safely such a large amount of digital information will be handled. India’s census began on April 1, 2026, and will run for about a year, with an estimated cost of 1.24 billion dollars, according to government planning figures. The process looks very different from the past, and what makes it “digital” is that data is no longer collected mainly on paper. Instead, information is entered, stored, and managed through online systems and mobile-based tools. For a short period of time, people can even enter their own data directly online.
The system tracks which households have already submitted their information online, so enumerators can see this when they arrive. If a household has self-reported, they mainly verify the details. If not, they collect the information directly during the visit. This helps ensure full coverage and prevents gaps or duplication. Even with the digital system, around 3 million enumerators are still essential. They visit homes, help people who didn’t complete the online form, and check that all data is accurate, especially in rural or hard-to-reach areas where internet access is limited.
The census is happening in two main phases. The first phase focuses on homes and buildings. Every structure is recorded, living conditions are documented, and many homes are geo-tagged so they can be placed precisely on digital maps. It creates a kind of national “living map” of housing across the country. The second phase shifts the focus to people. This is where the deeper details come in, including population data, education levels, employment, income, and social categories like caste. It is one of the most detailed snapshots of society the country has ever attempted. The inclusion of caste data has become one of the most controversial parts of the census.
The shift to a fully digital system has raised concerns about data security, privacy, and how such a large database will be protected from misuse or breaches. At the same time, questions remain about accuracy and how smoothly the system will work in practice. With a population this large and a new digital-first approach, experts point to risks like duplicate entries, missed households, or inconsistent data collection. Because census results shape everything from public services to electoral boundaries, even small errors can carry serious consequences. What makes India’s new census stand out is that most countries still aren’t fully digital. Many rely on workers going door to door, using tablets or even paper forms. Places like the United States and parts of Europe have added online options, but they still depend heavily on in-person follow-ups to make sure the data is accurate.
Going mostly digital from the start, especially in a country this large and diverse, is still uncommon—and some experts question whether the technology and infrastructure can handle it without gaps, errors, or people being left out.
