Decoding the delimitation numbers: The South worried delimitation could put them at a disadvantage, but government sources explain how it could increase the region’s number of Lok Sabha seats

While southern states express concern over the delimitation that the Center has proposed for the implementation of the Women’s Reservation Bill, government sources told News18 that the plan to increase the share of all states in the Lok Sabha equally to 50% will actually benefit the region.

Union Minister Kiren Rijiju wrote on Twitter, “Some people are trying to mislead South Indian states on women’s reservation by giving wrong delimitation figures. There should be no politics in giving reservation to women in Lok Sabha and Assemblies. All political parties are united for Nari Shakti.”

Analysis of numbers.

What is the Center planning to do?

Nari Shakti Vandan Act (officially the Constitution (106th Amendment) Act, 2023), originally passed in 2023, reserves one-third of all seats for women in the Lok Sabha, state assemblies and the Delhi Assembly.

Since it requires a new census and delimitation exercise before it can take effect, the law enacted in 2023 could only take effect after the next census (delayed to 2027), potentially extending the rollout to 2034.

Solution

To emphasize its implementation, the government proposes to delink reservation from the need for a fresh census and subsequent delimitation.

A central part of the plan is to increase the total number of Lok Sabha seats from 543 to 850In which 815 seats are proposed for states and the remaining 35 for union territories. Of these, 273 seats will be reserved for women. This expansion allows for a women’s quota without reducing the number of existing seats for current members.

The government plans to introduce a Delimitation Bill, 2026, to redraw constituency boundaries based on 2011 census data instead of waiting for new population data.

The government intends to bring a Constitution Amendment Bill for implementation of 33 per cent reservation for women in the Lok Sabha from 2029 in a special sitting of Parliament on April 16-18.

what does the government want

For constitutional amendments, the government will need a two-thirds majority in both houses to pass legislation.

Why are southern states against it? How do they understand delimitation

Southern states have historically invested more in education, health care, and family planning, leading to lower population growth than the North. Because delimitation is population-based, northern states like Uttar Pradesh and Bihar could gain a large number of seats—estimates suggest UP could rise from 80 to more than 140 seats.

The southern states, despite their developmental success, will see their relative share in Parliament decline. For example, Kerala may see 0% seat growth, while Tamil Nadu’s seat share may drop significantly.

A significant increase in seats from the northern states could lead to a permanent shift of national power towards the “Hindi heartland”.

Southern leaders fear that if some northern states form a majority on their own, their role in choosing the prime minister or passing national legislation will be diminished. There are concerns that national policies will be tailored to Northern priorities, potentially ignoring the unique industrial and social needs of the South.

Tax devolution (sharing of central taxes with states) already uses population as a key factor. The southern states make a disproportionately large contribution to India’s GDP and tax revenues. They fear that having fewer MPs will weaken their ability to bargain for a fair share of central funds, essentially leading to a situation where they will “pay more but get less”.

Critics argue that purely Arithmetical approach to delimitation Weakens the “spirit of federalism”.

Leaders like Tamil Nadu CM MK Stalin and Telangana CM Revanth Reddy argue that seats should be allocated based on broader factors such as economic contribution, good governance and education rather than just raw population numbers.

Delimitation may actually increase seats: What do government sources say?

“The 2011 population will not be the binding factor. This means nothing will change proportionally. This will allay the concerns of the southern states that their representation may decline,” sources said.

“There No harm to southern states. The ratio which is there today will be maintained. The headline number will increase by 50 per cent to 850 and the number for each state will also increase by 50 per cent,” he explained.

How the 50% formula will work: Explanation from government sources

• Tamil Nadu: There are currently 39 seats here. If the delimitation was done only on the basis of 2011 census, there would have been 49 seats. But as per the Government of India’s formula of increasing the share of all states proportionately by another 50%, it will now have 59 seats.
• Kerala: There are currently 20 seats here. If the delimitation was done only on the basis of 2011 census, there would have been 23 seats. But as per the Government of India’s formula of increasing the share of all the states proportionately and by 50%, it will now have 30 seats.
• Andhra Pradesh: There are currently 25 seats here. If the delimitation was done only on the basis of 2011 census, there would have been 33 seats. But as per the Government of India’s formula of increasing the share of all the states proportionately and by 50%, it will now have 37 seats.
• Odisha: Currently there are 21 seats here. If the delimitation was done only on the basis of 2011 census, there would have been 28 seats. But as per the Government of India’s formula of increasing the share of all the states proportionately and by 50%, it will now have 31 seats.
• Telangana: Currently there are 17 seats. If the delimitation was done only on the basis of 2011 census, there would have been 24 seats. But as per the Government of India’s formula of increasing the share of all the states proportionately and by 50%, it will now have 25 seats.
• Karnataka: There are currently 28 seats here. If the delimitation was done only on the basis of 2011 census, there would have been 41 seats. But as per the Government of India’s formula of increasing the share of all states proportionately by another 50%, it will now have 42 seats.

Indian group will oppose the bill

India Block leaders took this decision on Wednesday oppose the delimitation billI pushed for amendment in the Nari Shakti Vandan Act, 2023 to provide 33 percent reservation for women MLAs in the Lok Sabha and state assemblies.

The opposition clarified that it is not against women’s reservation and urged him to implement the Nari Shakti Vandan Act, 2023, but objected to the delimitation process, which it believes weakens the representation of southern and north-eastern states in the Lok Sabha.

This decision was taken in a meeting held at the residence of Congress President Mallikarjun Kharge in Delhi. Along with the Congress president, Leader of Opposition in Lok Sabha Rahul Gandhi, RJD working president Tejashwi Yadav, NCP (SP) MP Supriya Sule, Shiv Sena (UBT) MP Sanjay Raut, Rajya Sabha MP Kapil Sibal and other prominent Indian block leaders attended the meeting.

After the meeting, Mallikarjun Kharge announced India Bloc’s decision and accused the government of taking “politically motivated” steps to suppress opposition parties.

“We are all in favor of the Women’s Reservation Bill. But we have objection to the way they have brought it. It is politically motivated. Just to suppress the opposition parties.” Government It is doing. Although we have consistently supported the Women’s Reservation Bill, we insist that the earlier amendments be implemented. They are making some moves regarding delimitation. All our parties should unite and fight in the Parliament. Kharge said, we will oppose this bill, but we are not against reservation (for women).
