The "delimitation freeze" ends after 2026, and the upcoming exercise is being reimagined to address federal imbalances between northern and southern states.

• The "North-South" Gap: If representation is based strictly on population, northern states (e.g., UP, Bihar) could gain over 30 seats, while southern states (e.g., Tamil Nadu, Kerala) risk losing roughly 24 seats.
• Government Assurance: Union Home Minister Amit Shah has stated that "not a single seat will be reduced" in any southern state, suggesting a potential increase in the total number of Lok Sabha seats rather than redistribution.

Core Conflict

The "core conflict" of reimagining delimitation in 2026 centers on the tension between the democratic principle of population parity ("one person, one vote") and the federal principle of state equality.
1. The Population vs. Performance Dilemma

• The Northern Argument: States like Uttar Pradesh and Bihar argue that their current representation is inadequate, with each MP representing nearly 3 million voters compared to roughly 1.75 million in Kerala. They maintain that excluding population growth from seat allocation violates the constitutional mandate for equal voter influence.
• The Southern Concern: Southern states (Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, Telangana) argue that they are being penalized for success in population control, healthcare, and education. They fear a "demographic jackpot" for the North that would permanently diminish the South's political clout. 

2. Projected Shifts in Power
If seat allocation follows a strict population-based formula after 2026:

• Gainers: The "Hindi heartland" (UP, Bihar, Rajasthan, MP) could gain a combined 34 to 63 seats.
• Losers: The five southern states could lose as many as 24 seats (nearly 20% of their current total) if the Lok Sabha size remains at 543. Kerala alone could face a 30% reduction in its parliamentary voice. 

3. Fiscal and Policy Consequences

• Tax Inequity: Southern states contribute a disproportionately higher share of national GDP and tax revenue. They fear that lower political representation will lead to even more skewed Finance Commission allocations, where funds are diverted from "high-performing" states to "populous" ones.
• Language and Cultural Identity: There is deep apprehension that a Northern-dominated Parliament could impose policies—particularly regarding language rights—that are at odds with the cultural identity of non-Hindi speaking states. 

Possible Solutions to Prevent Unfair Outcomes

Experts and political bodies have proposed the following solutions to prevent unfair outcomes:

Increasing House Capacity to 848+ Seats

• To avoid a "zero-sum game" where some states lose seats for others to gain, a common proposal is to expand the Lok Sabha total.
• The 848-Seat Model: Increasing the total to roughly 848 or 866 seats allows for a proportionate increase that ensures no state loses its existing representation while adding seats to high-growth regions.
• Baseline Multiplier: One specific proposal suggests using the state with the lowest population growth (Kerala) as a baseline. Every state’s seat count would increase by a fixed multiplier (e.g., 68%), ensuring fairness across regions. 

Implementing "Degressive Proportionality"

• Based on the European Parliament model, this principle balances population size with state equality.
• Weighted Representation: Larger states (like UP and Bihar) get more seats overall but fewer seats per person, while smaller states get more representation per person.
• Compromise Formula: This ensures larger states do not completely dominate national legislation while still acknowledging their massive demographic size. 

Multi-Criteria Allocation (60:40 Formula)

Instead of raw population figures, new formulas propose using a "weighted index" for seat allocation:

• 60% weight to population size.
• 40% weight to performance indicators, such as demographic stabilization (Total Fertility Rate), human development indices, literacy, and tax effort. 

Strengthening the Rajya Sabha

To counterbalance a population-heavy Lok Sabha, reforms to the Upper House are being discussed:

• Equality of States: Adopting the U.S. Senate model where every state has an equal number of seats (e.g., 10 per state), regardless of population size.
• Enhanced Jurisdiction: Transforming the Rajya Sabha into a "Revenue Sabha" with a greater say in fiscal devolution to protect the economic interests of high-contributing southern states. 

Decoupling and Decentralization

• Cap on Lok Sabha Seats: Capping the Lok Sabha at 543 seats permanently to uphold federal status quo, while increasing the number of MLAs in State Assemblies to address representation needs at the local level.
• Fiscal Safeguards: Increasing devolution of funds to states and revising the Union/State lists to grant states more autonomy, thereby reducing the high stakes of central seat counts.
• Empowering Local Bodies: Shifting real governance power to panchayats and municipalities, which engage with citizens on a daily basis, making the federal seat imbalance less critical. 

Steps Taken by the Finance Commission (FC) to Ensure Fairness Between States

As of January 2026, the 16th Finance Commission (16th FC) is actively formulating its recommendations for the 2026–2031 period to balance the political and economic shifts caused by the post-2026 delimitation.
The Finance Commission has integrated several mechanisms to ensure that high-performing states (largely in the South) are not unfairly penalized for their demographic and economic progress:

Introduction of "Demographic Performance" Metric

To address fears that using recent census data (Census 2011 or upcoming 2027 data) would punish states with low birth rates, the Commission uses a Demographic Performance criterion. 

• How it works: This metric rewards states that have achieved lower Total Fertility Rates (TFR).
• Weightage: In previous cycles, this carried a 12.5% weight, acting as a direct financial reward for states that effectively managed population growth. 

Rewarding "Tax Effort" and Efficiency

The Commission includes a Tax Effort criterion (typically 2.5% weight) to incentivize states that show high efficiency in their own tax collection. This benefits economically advanced states that contribute significantly to the national exchequer but have smaller populations. 

Performance-Based and Sector-Specific Grants

Beyond the general divisible pool of taxes, the 16th FC is expanding the use of performance-linked grants: 

• Health and Education: Grants are earmarked for states that meet specific benchmarks in healthcare outcomes and educational quality.
• Million-Plus Cities Challenge Fund: For large urban centers, 100% of municipal grants are now performance-linked, rewarding cities that improve air quality and service delivery. 

 Addressing the "Income Distance" Gap

While the Income Distance criterion (45% weight) primarily helps poorer states catch up, the Commission is reviewing proposals to lower this weight. This would reduce the automatic diversion of funds from "rich" southern states to "populous" northern states. 

Conclusion
The Southern States must build consensus around the principle of degressive proportionality before the Delimitation Commission is constituted to safeguard federal fairness and long-term stability.
