With the upcoming post-2027 Census, India is expected to undertake a fresh delimitation exercise—a process that could significantly reshape parliamentary representation and political power across states.
📜 What is Delimitation?
Delimitation refers to the redrawing of boundaries of electoral constituencies to ensure:
-
Equal representation based on population
-
Fair distribution of seats
-
Balanced democratic participation
It is carried out by a Delimitation Commission appointed by the Government of India.
🏛️ Constitutional Basis
Delimitation is governed by:
-
Article 82 – After every Census, Parliament shall enact a Delimitation Act.
-
Article 170 – Pertains to state legislative assemblies.
The Delimitation Commission’s orders have the force of law and cannot be challenged in court.
🔒 Why Was Delimitation Frozen?
The allocation of Lok Sabha seats was frozen in 1976 (42nd Constitutional Amendment) to encourage population control.
Later, the freeze was extended until 2026 by the 84th Constitutional Amendment (2001).
This means that after the Census conducted post-2026 (likely Census 2027), a new delimitation exercise can be undertaken.
⚖️ Why It May Reconfigure Political Power
1️⃣ Population Shifts
Northern states (e.g., Uttar Pradesh, Bihar, Madhya Pradesh) have experienced higher population growth compared to southern states.
If seats are reallocated strictly on population basis:
-
Northern states may gain more Lok Sabha seats
-
Southern states may see relatively reduced proportional influence
2️⃣ Federal Balance Debate
Southern states argue that they should not be penalized for:
-
Effective population control
-
Better socio-economic indicators
This creates a debate between:
-
Population-based representation
-
Equitable federalism
3️⃣ Impact on Lok Sabha Strength
Currently:
-
Lok Sabha has 543 elected members
Post-delimitation:
-
Total number of seats may increase
-
Constituency boundaries will change
This could alter coalition dynamics and electoral strategies.
🌍 Broader Implications
-
Changes in political bargaining power
-
Redistribution of fiscal influence
-
Shift in national policy priorities
-
Potential regional tensions
It may also affect:
-
Reservation of SC/ST seats
-
Urban vs rural representation

🏁 Conclusion
The post-Census 2027 delimitation exercise could be one of the most consequential political reforms in contemporary India. While it aims to ensure democratic fairness through population-based representation, it also raises complex federal and regional questions.
