In April 2025, the longstanding and contentious issue of delimitation of parliamentary constituencies re-entered the national spotlight. As discussions around population-based seat redistribution gained momentum, tensions flared between India’s southern and northern states, highlighting deep fissures in the federal fabric of the country.
Delimitation refers to the redrawing of the boundaries of electoral constituencies to reflect changes in population. While the last exercise occurred in 2002 based on the 1971 Census, the next delimitation is expected post-2026, following a constitutional freeze that has remained in place for over four decades. The core principle behind delimitation is “one person, one vote,” implying proportional representation based on current demographic realities.
However, this principle poses a dilemma. Southern states like Kerala, Tamil Nadu, and Karnataka argue that they are being penalized for effective population control. These states have successfully implemented family planning measures and, as a result, have lower population growth compared to northern states like Uttar Pradesh and Bihar, where higher fertility rates persist. Under a strict population-based formula, northern states could gain significantly more seats in Parliament, while southern states risk losing their share of representation.
Critics of immediate delimitation warn that such an exercise may undermine the federal balance, reduce the political voice of progressive and developed regions, and reward states with weaker governance on population issues. They demand weighted representation, where factors such as human development indices, literacy rates, and economic contributions are considered along with population.
Supporters, however, maintain that democratic fairness requires proportional representation and that each citizen, regardless of state, should have equal weight in a parliamentary democracy. They argue that frozen representation has led to overrepresentation of less populous states, diluting the power of voters in more populous ones.
The Union Government has not yet taken a definitive stand but has constituted a high-level Delimitation Commission to study the implications. The debate has also triggered legal and constitutional discussions, especially regarding Article 81 and the scope of Parliament’s power to amend electoral boundaries.
As the 2026 deadline nears, the delimitation debate is not merely about numbers but reflects broader issues of federalism, equity, and regional identity. The outcome of this debate will significantly impact the future of India’s representative democracy.
