Bhubaneswar, June 4, 2025:The Government of India has announced that the upcoming 2027 national census will include caste-based population data for the first time in nearly a century—a landmark step that could trigger the redrawing of Lok Sabha and state assembly seats before the 2029 general elections.
Scheduled to begin on March 1, 2027, this will be India’s first caste-inclusive enumeration since 1931. Delayed due to the COVID-19 pandemic, the census process, including house listing and population counting, is now split across two phases starting in 2023. The 2027 census will be India’s first fully digital census, utilizing a mobile app and online portal for data collection.
Delimitation on the Horizon
Once completed, the 2027 census is expected to provide critical inputs for delimitation, the redrawing of parliamentary and legislative constituencies—a process that has remained frozen since 1976. The Delimitation Commission, upon reviewing the updated data, is likely to realign representation based on population shifts.
This is especially significant for northern states like Uttar Pradesh and Bihar, which have witnessed high population growth and may gain additional seats. In contrast, southern states such as Tamil Nadu, Kerala, and Andhra Pradesh, with comparatively lower fertility rates, could potentially lose representation.
In 2019, there was a proposal to expand the Lok Sabha from 543 to 848 seats, but critics argue that the larger states in the north would still gain disproportionately, affecting the federal balance.
Caste Census: Push and Pull of Political Demand
Union Minister Ashwini Vaishnaw, announcing the digital rollout on April 30, said that integrating caste data will boost transparency and development planning. He noted that while the 2011 census provided detailed data for Scheduled Castes (201 million) and Scheduled Tribes (104 million), it lacked comprehensive figures for Other Backward Classes (OBCs) and other castes.
Congress leader Rahul Gandhi, a strong proponent of the caste census, responded on X (formerly Twitter):
“Because of our demands, the government is now considering caste-based population counting.”
However, he also criticized state-level surveys by opposition-run governments in Bihar and Karnataka as politically motivated and lacking in credibility.
Social Justice and Representation in Focus
The Gazette of India will notify the 2030 census plan under the Census Act of 1948 on June 16, 2025, but political debate has already begun. Caste census data is expected to influence reservation policies, resource allocation, and welfare programs, giving rise to more assertive calls for social justice.
While supporters view it as essential for equitable development and policy-making, critics warn of social tensions and regional imbalances. Southern states fear the redistribution of power and funds, citing concerns over being penalized for better population control.
Looking Ahead to 2029 Elections
As India inches closer to the 2029 general elections, the 2027 census may emerge as a game-changer, reshaping the electoral map, social justice narrative, and federal equations. With caste data expected to drive demands for revised quotas and regional power shifts, the road to 2029 promises intense debate and high-stakes politics.
