A majority of Indians view elections as a contest centred on candidates, parties and manifestos. Delimitation rarely enters this discourse, largely due to its multi-layered structure and dense bureaucratic jargon that is confusing to the average voter. Often only attorneys, bureaucrats and election officials are aware of this background constitutional process. In addition to conducting state-specific exercises in Mizoram, Arunachal Pradesh, Goa, Jammu and Kashmir and Assam, India has periodically updated electoral boundaries since 1951 through a series of Delimitation Commission acts and decrees. However, in the coming years, delimitation might turn out to be the most significant political endeavour the country has carried out since its inception.

The exercise concerns the allocation of political authority: Who gets represented? Whose votes hold more weight and which regions disproportionately benefit from each parliamentary seat assigned and reserved constituency recognised? Although boundaries may seem merely administrative on paper, they have long-lasting effects on governments, social cohorts and the cultural anxieties that have been haunting India for the past few years. The Special Intensive Revision (SIR) of electoral records has been at the forefront of the present discussion. This adjudication, however, only presents half the picture independently. Certainly, elections are determined by who gets the right to vote. Yet how votes are converted into political representation is decided by delimitation. It is impossible to comprehend one without the other. Before understanding the extent of delimitation’s impact, it is pertinent to question who stands to benefit from it.History of delimitation in India – the first delimitation exerciseDespite general perceptions, delimitation is not a single exercise. It carries out three different constitutional duties. First, in order to reflect population shifts, it redraws boundaries of assembly and parliamentary constituencies. Second, it redistributes reserved seats in accordance with the demographic distribution of Scheduled Castes, Scheduled Tribes and women population. Third, it establishes the number of parliamentary seats each state is permitted in the Lok Sabha, making it a politically delicate process.According to the constitution, this exercise is supposed to occur after each population census. As a result, Delimitation Commissions were instituted under successive Delimitation Commission Acts following the 1951, 1961 and 1971 censuses.Table 2: India’s First Delimitation (1951-52)IndicatorFigurePopulation (1951 Census)361.1 millionEligible voters enrolled173.2 millionLok Sabha seats489Parliamentary constituencies401State Assembly constituenciesOver 3,200 (across Part A*, B** and C*** States)Polling stations~196,000Election officials deployedNearly 1 millionPart A States: Former Governor’s Provinces (e.g., Madras, Bombay, Uttar Pradesh, Bihar); Part B States: Former princely states or unions (e.g., Hyderabad, Mysore, Rajasthan, Jammu & Kashmir); Part C States: Chief Commissioner’s Provinces and smaller territories (e.g., Delhi, Himachal Pradesh, Bhopal, Ajmer, Coorg).

It created the electoral map for the 1951-52 general election based on the 1951 census (361.1 million people) and the Representation of the People Act, 1950. In order to guarantee SC and ST representation, the process established 401 parliamentary constituencies that would elect 489 Lok Sabha members, including a number of multi-member constituencies. Additionally, it defined more than 3,200 assembly seats, granting 173.2 million people the right to vote in the biggest democratic election in history. The exercise’s consideration for inclusion was noteworthy.The Election Commission provided unique emblems to political parties and candidates so voters could differentiate them on the ballot paper, as nearly 85% of the populace was illiterate. Over 224,000 polling booths were set up nationwide, many of them in isolated forests, deserts and Himalayan communities (the number of booths vary slightly between official compilations depending on counting methods). It was both a democratic and an administrative accomplishment.The goal was simple: to give the democratic concept of “one person, one vote, one value” real meaning by ensuring that each elected representative symbolised approximately the same number of people. Furthermore, it was guided by a federal compact that provides that “non domination of states, i.e., ratio of states to the Parliament must be proportional, giving a way for asymmetrical federalism (special accommodated situations).”The second and third delimitation commissionsIndia’s first significant electoral boundary modification following independence was carried out by the Second Delimitation Commission, which was established under the Delimitation Commission Act, 1962. The electoral map was updated to reflect a population growth of about 78 million since 1951 using data from the 1961 Census (439.2 million people). The 522 elected Lok Sabha seats were kept in the exercise, but 79 SC and ST reserved seats were reassigned and constituencies were redrawn to balance the population. The 1967 general election saw the implementation of the updated boundaries, which upheld the constitutional precept that representation should vary in tandem with demographic shifts.Table 3: India’s Second Delimitation (1963-67)IndicatorFigurePopulation (1961 Census)439.2 millionIncrease since 1951+78.1 million (21.6%)Delimitation Commission Act1962Commission constituted1963Elected Lok Sabha seats522SC reserved Lok Sabha seats79ST reserved Lok Sabha seats30Implemented for1967 General ElectionSource: Census of India, 1961; Delimitation Commission Act, 1962; Election Commission of India, Statistical Report on the Fourth General Election (1967).The final national redistribution of parliamentary representation prior to the constitutional freeze was completed by the Third Delimitation Commission, which was established under the Delimitation Commission Act of 1972. The exercise redrew parliamentary and assembly constituencies to reflect a population growth of almost 109 million since 1961, based on the 1971 Census (548.2 million). The commission also redistributed reserved constituencies based on changes in population and geographical distribution, ensuring that reservation continued to reflect the demographic composition recorded in the latest census. The final delimitation to change the interstate distribution of parliamentary seats prior to the freeze enforced during the 1975 Emergency resulted in the new electoral map, which came into effect before the 1977 general election.Table 4: India’s Third Delimitation (1973-77)IndicatorFigurePopulation (1971 Census)548.2 millionIncrease since 1961+109.0 million (24.8%)Delimitation Commission Act1972Commission constituted1973Census used1971 CensusElected Lok Sabha seats543SC reserved Lok Sabha seats77ST reserved Lok Sabha seats41Implemented for1977 General ElectionSource: Census of India, 1971; Delimitation Commission Act, 1972; Election Commission of India; Constitution of India.Emergency and the freeze on delimitationHowever, India quickly faced a constitutional conundrum. State-by-state variation in population growth enhanced in the 1970s. While fertility declined in southern and western states owing to investment in family planning, public health and female education, population growth in much of northern India continued to rise at a sharp rate. This meant that states which had adopted population control strategies would gradually lose representation in the parliament if legislative seats continued to be redistributed solely on population. States with higher fertility rates would receive more seats, essentially punishing the very states that adhered to national policy. The response to this dilemma came during the Emergency.Through the 42nd Constitutional Amendment Act, 1976, parliament froze the allocation of Lok Sabha seats among states until after the first census conducted after 2000. The objective was explicitly linked to encouraging family planning.The fourth delimitation commissionDelimitation was restarted in India more than 30 years after the freeze. The Fourth Delimitation Commission, which was established under the Delimitation Act of 2002, redrew state-level parliamentary and assembly constituency boundaries using data from the 2001 census, which included 1.03 billion people.Nevertheless, until after the first census post 2026, the distribution of Lok Sabha seats remains fixed according to the 84th Constitutional Amendment, 2001. To reflect the most recent demographic distribution, the commission also reassigned 47 ST and 84 SC reserved parliament seats.Table 5: Fourth Delimitation Commission (2002–08)IndicatorFigurePopulation (2001 Census)1.03 billionIncrease since 1971*+480.8 million (87.7%)Delimitation Act2002Commission constituted2002Census used2001 CensusLok Sabha seats543 (unchanged)SC reserved Lok Sabha seats84ST reserved Lok Sabha seats47*The 1981 and 1991 Censuses were not used for delimitation because the constitutional freeze remained in force. Source: Delimitation Act, 2002; Delimitation Commission of India; Census of India, 2001; Election Commission of India.The fact that India did not stop delimitation altogether, but froze only one part of it is often overlooked.The 2002 Delimitation Commission went on to redraw parliamentary and assembly constituencies across most states. Its recommendations came into effect in 2008, altering constituency boundaries and revising the distribution of reserved seats without changing the total number of allocated seats.For nearly five decades, this constitutional compromise has held together two competing democratic principles: equality in representation so that each vote carries equal weight and preservation of India’s federal balance by ensuring that states were not disadvantaged for implementing population-control policies.The coming delimitation will have to reconcile these principles once again. Today’s India, however, is very different from the India of 1976.The path aheadGrowth in population has become increasingly uneven. Cities have evolved due to internal migration and urban centres have expanded well beyond their administrative boundaries. New economic centres have sprung up, while older districts have languished. India’s urban population increased from 27.8% in 2001 to 31.2% in 2011, with 377 million people living in urban regions, according to the 2011 census.These changes are structural rather than minor and the upcoming delimitation is probably going to be much more significant than the previous ones.The new exercise will not just redefine boundaries of constituencies, but will effectively alter the distribution of power among states, rearrange reserved seats and have a pervasive impact on the social and political coalitions that underline Indian political life.Since states were reorganised along linguistic lines in the 1950s, this movement may constitute the biggest reorganisation of representative democracy.This is why politics surrounding delimitation has become immensely charged. The ruling party sees in it the chance to influence the distribution of political representation in the country for decades to come. Concurrently, concerns about protecting India’s federal structure have emerged among regional parties. One of the most significant constitutional discussions of our day takes place between these opposing ideologies.The familiar framing of this debate is that it pits the north against the south. But that, as the next article will argue, barely scratches the surface of a much deeper fault line.Nirmanyu Chouhan is a researcher of politics and society. @media(max-width:768px){tbody{font-size:12px}td{border:1px solid #000!important}}
