India Launches Comprehensive Census Amid Population Shifts

As India initiates its most extensive population survey in over a decade, more than a billion residents will be asked 33 key questions covering everything from housing conditions to digital connectivity. The exercise, spanning two phases, aims to capture detailed insights into demographics, economic activity, and social structures, with over three million enumerators expected to complete the work within a year.

The census, now in its 16th iteration and the eighth since independence in 1947, will include caste data as well as information on internet access, mobile phone usage, and household composition. This comes at a pivotal time, as the nation’s population surpasses 1.4 billion, with the UN Population Fund noting India’s 2023 milestone. Despite this growth, the country remains one of the youngest in the world, with nearly 70% of its citizens in the working-age group.

Complicating the timeline, the 2021 census was postponed due to pandemic disruptions and administrative scheduling, marking the first time the decennial survey missed its deadline. The survey will cover 36 states and federal territories, encompassing over 7,000 sub-districts, 9,700 towns, and nearly 640,000 villages. Enumerators, often schoolteachers or local officials, will conduct fieldwork, while digital tools will streamline data collection.

Modernization and Innovation in Data Gathering

For the first time, the census will feature self-enumeration, allowing residents to input details online via a 16-language portal. Each participant will receive a unique ID for verification by census workers. The first phase, focusing on housing conditions and household assets, will run from 1 April to 15 May in selected regions, including Delhi, Karnataka, and Mizoram. The second phase, targeting population demographics, is set for February 2027.

India’s census has evolved significantly since its colonial origins. The initial 1872 survey, a simple headcount, included just 17 questions. By 1881, it had expanded to record identity, social markers, and basic education levels. Over time, the questionnaire incorporated more nuanced aspects like employment status, migration patterns, and disability classifications, reflecting the nation’s shifting priorities.

“A couple in a live-in relationship can be recorded as married if they consider their ‘relationship as a stable union’—signalling a quiet shift towards redefining household structures.”

The 1941 census marked a turning point, adding questions about daily life and economic behavior. Post-independence censuses further broadened the scope, addressing nationality, land ownership, and displacement from events like Partition. In recent years, the focus has turned to tracking modernization, including commuting habits, education trends, and detailed fertility data. This latest iteration continues that trend, adapting to contemporary societal changes.
