Delimitation

Why Delimitation in Spotlight?

• Delimitation of Lok Sabha and State Legislative Assembly constituencies is scheduled after the first Census post-2026.
• The 2021 Census was delayed due to the COVID-19 pandemic.
• Government decisions further postponed the Census process.
• South Vs North: Will North India’s Gain be South India’s Loss?

What is Delimitation?

Delimitation is the process of redrawing the boundaries of electoral constituencies, including those for the Lok Sabha and State Legislative Assemblies, to reflect changes in population demographics. It ensures fair and equal representation by adjusting constituency sizes so that each elected representative represents a similar number of voters.

In India, this process is conducted by the Delimitation Commission, an independent body appointed by the government. The primary goal is to maintain balanced political representation, ensuring that every vote holds equal weight in legislative decision-making.

Functions of Delimitation

Delimitation serves multiple vital functions to uphold fair and democratic representation in legislative bodies:

• Allocation of Seats: It determines the number of seats for the Lok Sabha and State Legislative Assemblies based on population data, ensuring proportional representation across regions.
• Reservation of Seats: Delimitation identifies constituencies reserved for Scheduled Castes (SC) and Scheduled Tribes (ST) communities, safeguarding political representation for marginalized groups.
• Defining Electoral Boundaries: It redraws the boundaries of electoral constituencies to reflect shifts in population and demographic changes, ensuring equal distribution of voters in each constituency.
• Maintaining Uniformity: The process ensures that the number of voters in each constituency is balanced, preventing discrepancies that could lead to unequal representation.
• Avoiding Overlapping Jurisdictions: By clearly marking boundaries, delimitation prevents overlapping of constituencies, which helps in better administrative management during elections.
• Facilitating Fair Elections: Properly defined constituencies lead to more organized elections, reducing the scope for electoral malpractices and confusion.
• Independent and Transparent Process: The Delimitation Commission, an autonomous body, carries out the process independently, ensuring transparency and impartiality. Its decisions are binding and cannot be challenged in any court of law.
• Reflecting Census Updates: Delimitation is carried out based on the latest Census data, ensuring that the changes in population and migration patterns are accurately represented in legislative constituencies.
• Promoting Political Stability: By providing fair representation to all regions, delimitation helps maintain political stability and trust in the democratic process.
• Supporting Governance: Well-defined constituencies enable effective governance by ensuring elected representatives cater to the appropriate number of citizens.

Purpose and Significance of Delimitation

Delimitation serves as a critical mechanism in India's democratic framework, ensuring fair and equal representation in legislative bodies.

• Ensures Equal Representation: It guarantees the principle of one person, one vote by aligning constituency boundaries with population size, ensuring each vote carries equal weight.
• Adjusts for Population Shifts: Delimitation reflects demographic changes such as population growth, migration, and urbanization, thereby maintaining a fair regional balance in representation.
• Protects Federalism: By realigning constituencies based on development and population changes, it supports the federal structure of India, ensuring all regions are fairly represented in decision-making.
• Decides SC/ST Reserved Seats: It marks constituencies reserved for Scheduled Castes (SC) and Scheduled Tribes (ST) to ensure political participation and representation for marginalized communities.
• Prevents Gerrymandering: Delimitation ensures that electoral boundaries are drawn fairly and impartially, preventing manipulation for political advantage.
• Improves Governance: Balanced constituencies help elected representatives govern more effectively, as population disparities are minimized.
• Enhances Voter Engagement: With clearer boundaries and balanced representation, voter engagement and trust in the electoral process are strengthened.
• Facilitates Effective Electoral Management: Properly defined constituencies streamline the election process, making it easier to manage polling stations and voter lists.
• Reflects Socio-Economic Changes: Delimitation takes into account shifts in economic activities and urban development, ensuring representation is aligned with current realities.
• Strengthens Democratic Accountability: By ensuring equal voter distribution, representatives are held accountable to a balanced and diverse electorate.
• Supports Political Stability: Equitable distribution of representation reduces regional disparities, contributing to political stability and social harmony.
• Mandated by the Constitution: Delimitation is mandated under Articles 82 and 170 of the Indian Constitution, highlighting its significance in maintaining democratic integrity.

Core Concern

• Since 1976: The allocation of seats has been frozen based on the 1971 Census population data.
• Underrepresentation: This freeze has caused underrepresentation of northern states in Parliament and State Assemblies.
• Rapid Growth in Hindi Belt: States such as Uttar Pradesh, Bihar, Madhya Pradesh, and Rajasthan have experienced rapid population growth during this period.
• Mismatch in Representation: Despite their increasing populations, these states have seen little to no increase in their political representation, leading to a mismatch between population size and seats allocated.

Logic Used by the Delimitation Commission in 1971

The 1971 Delimitation Commission, constituted under the Delimitation Act of 1972, adopted a clear-cut method of proportional representation grounded in the population figures from the 1971 Census.

Key Logic in 1971:

Population per MP Calculation:

State-wise Seat Allocation:

Constitutional Mandate:

Reservation of Seats:

Goal in 1971:

• Ensure fair and equal representation across all states in India.
• Allocate parliamentary seats strictly based on the actual population data.
• Minimize differences in the number of people each MP represents for balanced voter weight.

Why Was the Logic Frozen?

• Policy Rationale: To avoid discouraging states from implementing population control measures, the government decided not to adjust seat allocation frequently.
• 42nd Constitutional Amendment (1976): Froze the allocation of seats in the Lok Sabha and State Assemblies based on the 1971 Census until the year 2000.
• Population Control Incentive: This freeze was intended to ensure that states successfully controlling their population would not lose political representation compared to states with higher population growth.
• Extension by 84th Amendment (2001): The freeze was extended, pushing the deadline for revising seat allocation to 2026.
• Population Growth vs Representation: Despite the population more than doubling since 1971, the total number of Lok Sabha seats has not increased, maintaining the seat distribution from the 1971 Census.
• Resulting Underrepresentation: This decision has led to some states, especially those with rapid population growth, being underrepresented in Parliament and State Legislatures.

Proposed Logic Post-2026 (Likely)

The proposed delimitation process after 2026 is expected to build on the fundamental principles established in 1971, but with important updates and refinements. It will be based on the first Census conducted after 2026, likely the 2031 Census.

The calculation for population per Member of Parliament (MP) will use the total population divided by a possible expanded Lok Sabha size of 848 seats.

With India’s projected population around 1.52 billion in 2031, this means each MP would represent approximately 18 lakh people. Seat allocation will be done proportionally, with rounding and adjustments made to maintain a balance that respects federal principles.

Additionally, reserved seats for Scheduled Castes, Scheduled Tribes, and women—aligned with the 33% reservation law—will be updated to reflect the latest demographic data.

What Will Change?

Issues with the Current Freeze (Based on 1971 Census)

• 42nd Amendment (1976): Froze the allocation of parliamentary seats until 2000, a freeze that was later extended to 2026.
• 84th Amendment (2001): Permitted only the redrawing of constituency boundaries but did not allow an increase in the total number of seats.
• 87th Amendment (2003): Used the 2001 Census data for boundary adjustments but kept the state-wise seat distribution unchanged.
• Unequal Representation: As a result, this freeze has caused unequal representation in Parliament, giving some states disproportionate influence.
• Imbalanced Funding: It has also contributed to imbalanced allocation of government funding, affecting fair development across regions.

Impact of Delimitation on SC/ST and Women Representation

The upcoming delimitation exercise is poised to significantly enhance representation for Scheduled Castes (SC), Scheduled Tribes (ST), and women in Parliament:

SC/ST Representation:

• Articles 330 and 332: SC/ST communities are allocated reserved seats based on their population, as mandated by the Indian Constitution.
• Current Allocation: Around 131 seats are reserved for SCs and STs in the Lok Sabha.
• Future Projection: If the Lok Sabha expands to 848 seats, the reserved seats for these communities are expected to exceed 200, improving political representation and promoting social equity.

Women Empowerment through 33% Reservation:

• Women’s Reservation Act: Delimitation will activate this law, mandating 33% reservation for women in Parliament.
• Existing Structure: In the current 543-seat Lok Sabha, this means approximately 181 seats would be reserved for women.
• Post-Expansion: With 848 seats, women’s reserved seats would rise to about 280, significantly boosting women’s leadership, especially in rural and underrepresented regions.

Empowerment + Representation = Inclusive Politics

• This increased representation for SCs, STs, and women will foster a more inclusive, equitable, and participatory democracy by empowering marginalized voices and strengthening grassroots governance.
