Representation
The most fundamental principle of democratic representation is that the distribution of seats among constituencies should reflect the actual distribution of population. A House of the People elected from constituencies of wildly unequal population size would violate the "one person, one vote" principle — some citizens would have greater representation weight than others simply by virtue of where they live.
Articles 81 and 82 of the Constitution establish the constitutional framework for Lok Sabha seat allocation and its periodic readjustment in line with census data. Article 81 fixes the composition and the broad allocation principles; Article 82 requires that this allocation be readjusted after each decennial census.
Yet since 1976, this readjustment has been frozen — constitutionally suspended — by successive constitutional amendments. The total number of Lok Sabha seats and the inter-State allocation of those seats have remained fixed at their 1971-census levels for more than five decades.
This freeze, the reasons for it, and its imminent end after the first census post-2026, are among the most politically and constitutionally consequential features of contemporary Indian electoral law.
Article 81
Maximum Strength
Article 81(1) provides that the House of the People shall consist of not more than 550 members, of whom not more than 530 shall be representatives of States (chosen by direct election) and not more than 20 shall be representatives of Union Territories. Parliament may prescribe the manner of choosing representatives of Union Territories.
The Constitution also provides that the President may nominate not more than two members of the Anglo-Indian community under Art. 331 — though this provision has been removed by the Constitution (104th Amendment) Act, 2019. The current effective maximum is 543 elected seats (530 States + 13 Union Territories), with the Lok Sabha presently having 543 elected members.
Population Ratio
Article 81(2) provides that the allocation of seats among the States shall be determined on the basis of the ratio of the number of seats allocated to a State to the population of that State, so that this ratio is, as nearly as possible, the same for all States.
This is the constitutional expression of proportional representation: each State's share of Lok Sabha seats should correspond to its share of the national population.
The Commentary notes that the use of the word "population" in Art. 81(2) refers to the ascertained population at the preceding census — making the decennial census the direct constitutional trigger for seat readjustment.
SC/ST Reservation
Article 332 (and the analogous State provision) reserves certain constituencies for Scheduled Castes and Scheduled Tribes in proportion to their population.
The number of reserved seats in the Lok Sabha is determined as part of the delimitation exercise — constituencies with high SC/ST population concentrations are designated as reserved, and only SC/ST candidates may contest from those seats. The delimitation freeze has correspondingly frozen the number and location of reserved constituencies.
Article 82
Constitutional Duty
Article 82 provides:
Upon the completion of each census, the allocation of seats in the House of the People to the States and the division of each State into territorial constituencies shall be readjusted by such authority and in such manner as Parliament may by law determine: Provided that such readjustment shall not affect representation in the House of the People until the dissolution of the then existing House.
The Article establishes a constitutional obligation — not merely a power — to readjust seat allocation and constituency boundaries after each census. The readjustment is mandated; what Parliament may determine is the manner and the authority (i.e., through the Delimitation Commission).
The proviso ensures continuity: a readjustment made after a census does not affect the composition of the then-existing Lok Sabha — it takes effect only from the next general election after the readjustment.
Delimitation Commission
Parliament has consistently discharged its Art. 82 obligation through the Delimitation Commission — a statutory body appointed under the Delimitation Acts. The Commission readjusts both the inter-State allocation of seats and the intra-State division of each State's allocation into territorial constituencies.
Freezing History
42nd Amendment
The Constitution (Forty-Second Amendment) Act, 1976 inserted an important qualification into Art. 82 (and the parallel Art. 170 for State Assemblies): the total number of seats in the Lok Sabha and their allocation among States was frozen at the figures established on the basis of the 1971 census, pending the completion of the first census after the year 2000.
This freeze meant that even though the population of India grew substantially between 1971 and 2001, the Lok Sabha's seat count and inter-State distribution remained unchanged. The same 543 seats were allocated in the same proportions as in 1971, notwithstanding dramatic changes in the relative populations of different States.
84th and 87th
The Constitution (Eighty-Fourth Amendment) Act, 2001 further extended the freeze until after the first census following the year 2026. The total seat count and inter-State allocation remain fixed at the 1971-census figures until then.
The Constitution (Eighty-Seventh Amendment) Act, 2003 modified the arrangement slightly — allowing internal constituency boundary readjustment within States on the basis of the 2001 census, while keeping the inter-State allocation frozen.
Why the Freeze
The constitutional rationale offered for the freeze is tied to India's population policy.
Before the 42nd Amendment, there was concern that States which had successfully implemented family planning programmes — particularly the southern States of Tamil Nadu, Kerala, Karnataka, and Andhra Pradesh — would be penalised in parliamentary representation relative to northern States with higher population growth rates.
If seats were redistributed based on post-1971 census data, fast-growing northern States (especially Uttar Pradesh, Bihar, and Madhya Pradesh) would gain seats while demographically stable or declining southern States would lose seats.
The freeze was intended to remove the perverse incentive against population control: States should not be rewarded with more Lok Sabha seats for failing to control their population, nor should States be punished with fewer seats for succeeding.
Post-2026 Scenario
First Census
The freeze will end after the first census completed following 2026. The census that was scheduled for 2021 was postponed (the 2021 census has not yet been conducted as of the date of this writing). When the next census is completed, the constitutional obligation under Art. 82 will activate: a Delimitation Commission will be constituted to readjust seat allocation across States based on the new population data.
This readjustment will likely result in significant changes to the distribution of Lok Sabha seats. States that have grown more rapidly since 1971 — principally Uttar Pradesh, Bihar, Rajasthan, Madhya Pradesh — will gain seats; States that have grown more slowly — principally Kerala, Tamil Nadu, Andhra Pradesh, Telangana, Karnataka — may face a reduction in their share of Lok Sabha representation.
Implications
The post-2026 delimitation is the subject of significant political controversy. Southern State governments and political parties have argued that the readjustment will punish them for demographic success and reduce their political representation in Parliament disproportionately to their economic and social contribution to the nation.
The debate over whether the total number of Lok Sabha seats should be increased (to allow southern States to maintain their absolute seat count while northern States are allocated more) is one of the most consequential ongoing constitutional discussions in India.
North-South Divide
The political tension encoded in Arts. 81-82 is fundamentally a tension between two conceptions of democratic representation:
Population-proportional representation holds that each citizen's vote should carry equal weight — more populous States should have more seats. This principle, strictly applied, rewards population growth.
Outcome-weighted representation argues that States should be represented in proportion to the values the Constitution encourages — including population stabilisation. A formula that penalises demographic success is, on this view, constitutionally unsound.
The 1976 freeze was an attempt to resolve this tension in favour of the second position. The post-2026 readjustment will re-open it — with consequences for the representational balance between India's demographically fast-growing North and its slower-growing (but economically more developed) South.
Conclusion
Articles 81 and 82 establish the constitutional bedrock of Lok Sabha representation: that seats shall be proportionate to population and shall be readjusted after each census. The five-decade freeze — constitutionally mandated through the 42nd, 84th, and 87th Amendments — has suspended this readjustment as a deliberate policy choice to prevent demographic success from being electorally penalised.
The approaching end of the freeze, when the next census triggers the Art. 82 readjustment, will be a defining constitutional moment.
How India resolves the representational tension between North and South, between population growth and population stabilisation, between democratic arithmetic and federal equity, will shape the composition of the Lok Sabha — and therefore the character of Indian democracy — for the decades to come.
Frequently Asked Questions
Q: What does Article 82 require?
Article 82 requires that upon the completion of each census, the allocation of Lok Sabha seats among States and the division of each State into territorial constituencies shall be readjusted by Parliament's designated authority (the Delimitation Commission).
Q: Why have Lok Sabha seats been frozen since 1971?
The Constitution (42nd Amendment) Act, 1976 froze seat allocation at 1971-census levels to prevent States that succeeded in controlling population growth from losing parliamentary representation relative to faster-growing States. The freeze was extended to 2026 by the 84th Amendment (2001).
Q: How many seats does the Lok Sabha currently have?
The Lok Sabha currently has 543 elected seats (530 for States and 13 for Union Territories), based on the 1971 census allocation that has been in effect since 1977.
Q: When will the seat freeze end and delimitation occur?
The freeze will end after the completion of the first census following the year 2026. A Delimitation Commission will then be constituted to readjust seat allocation and constituency boundaries based on the new census data.
Q: What is the controversy about the post-2026 delimitation?
Southern States — which have achieved lower population growth rates — fear they will lose Lok Sabha seats relative to northern States with higher population growth. This has generated debate about whether the total seat count should be increased, and about the principles that should govern representation in a federal democracy.
