Understanding the delimitation exercise | Explained

The story so far: The delimitation of constituencies for the Lok Sabha and State Legislative Assemblies is to be carried out on the basis of the first Census after 2026. The 2021 Census was originally postponed due to the COVID-19 pandemic and subsequently due to delays on the part of the Central government.

What is delimitation?

Delimitation means the process of fixing the number of seats and boundaries of territorial constituencies in each State for the Lok Sabha and Legislative assemblies. It also includes determining the seats to be reserved for Scheduled Castes (SC) and Scheduled Tribes (ST) in these houses. Article 82 and 170 of the Constitution provide that the number of seats in the Lok Sabha and State Legislative assemblies as well as its division into territorial constituencies shall be readjusted after each Census. This ‘delimitation process’ is performed by the ‘Delimitation Commission’ that is set up under an act of Parliament. Such an exercise was carried out after the 1951, 1961 and 1971 Census.

What is the constitutional requirement?

‘Democracy’ means ‘rule or government by the people’. It follows that the government is elected by a majority with the broad principle of ‘one citizen-one vote-one value’. The number of seats in the Lok Sabha based on the 1951, 1961 and 1971 Census was fixed at 494, 522 and 543, when the population was 36.1, 43.9 and 54.8 crore respectively. This broadly translated to an average population of 7.3, 8.4 and 10.1 lakh per seat respectively.

However, it has been frozen as per the 1971 Census in order to encourage population control measures so that States with higher population growth do not end up having higher number of seats. This was done through the 42nd Amendment Act till the year 2000 and was extended by the 84th Amendment Act till 2026. Hence, the population based on which the number of seats is allocated refers to the population as per the 1971 Census. This number will be re-adjusted based on the first Census after 2026. The boundaries of territorial constituencies were readjusted (without changing the number of seats) and seats for SC and ST were determined as per the 2001 Census and will again be carried out after 2026.

In a normal course of events, the delimitation process for the number of seats, boundaries of territorial constituencies and determining the reserved seats for SC and ST would have happened based on the Census of 2031 as it would have been the first Census after 2026. However, with the 2021 Census now being postponed and the year 2026 nearing, there have been talks about the impending delimitation exercise.

What are the issues?

The number of seats were frozen based on the 1971 Census in order to encourage population control measures. The population explosion that happened in our country during the last five decades has been uneven with some States like Uttar Pradesh, Bihar, Madhya Pradesh and Rajasthan having a greater increase than States like Kerala, Tamil Nadu, Karnataka and Andhra Pradesh. There are two options that are being discussed in the public domain with respect to the revised delimitation exercise based on the projected population of various States as of 2026.

The first is to continue with the existing 543 seats and their redistribution amongst various States (Table 1) and the second is to increase the number of seats to 848 with proportionate increase among various States (Table 2).

It can be noticed in both these scenarios that the southern States, the smaller states in the north like Punjab, Himachal Pradesh and Uttarakhand, as well as the northeastern States are bound to be at a disadvantage when compared to the northern States of Uttar Pradesh, Bihar, Madhya Pradesh and Rajasthan. This may go against the federal principles of our country and may lead to a feeling of disenchantment in the population of the States that stand to lose in their representation. It also goes against the philosophy of freezing seats as per the 1971 Census with the States that have been better at controlling the population losing out on their political significance.

What are international practices?

In a federation like the U.S., the number of seats in the House of Representatives (the equivalent of our Lok Sabha) has been capped at 435 since 1913. The population of the country has increased almost four times from 9.4 crore in 1911 to an estimated 33.4 crore in 2023. The seats among the States are redistributed after every Census through the ‘method of equal proportion’. This does not result in any significant gain or loss for any of the States. For example, based on the Census of 2020, the reapportionment has resulted in no change in the number of seats for 37 States. Texas gained two seats, five other States gained one seat each and seven States lost one seat each.

In the European Union (EU) Parliament which consists of 720 members, the number of seats is divided between 27 member countries based on the principle of ‘degressive proportionality’. Under this principle, the ratio of population to the number of seats shall increase as the population increases. For example, Denmark with a population of around 60 lakh has 15 seats (average population of 4 lakh per member) as against Germany with a population of 8.3 crore having 96 seats (average population of 8.6 lakh per member).

What can be an ideal solution?

The issue arises because democratic and federal principles seem to be at loggerheads in the delimitation exercise as envisaged. However, they can be harmoniously reconciled by giving equal importance to both. The main work of a Member of Parliament is to legislate on ‘Union List’ matters like Defence, External Affairs, Railways, Telecommunication, Taxation etc. and hold the Central government accountable. Majority of the schemes of the Central government are implemented only by the State governments. Hence, the number of MPs in Lok Sabha may be capped at the present number of 543 which would ensure no disruption in the present representation from various States. This will maintain and uphold the federal principle. The number of MLAs in each State may be increased in line with current population (without changing the number of Rajya Sabha seats) to address the democratic representational requirement. However, the most important reform for strengthening democracy is to empower the local bodies of panchayats and municipalities who engage with the citizens on a day-to-day basis. The devolution of powers and finances to these bodies must be significantly increased to strengthen democracy at grass root levels.
