What is Delimitation Commission?
Historical Background
Key Points
12 points- 1.
The core function of the Delimitation Commission is to determine the number of seats to be allocated to each state in the Lok Sabha and State Assemblies, and to divide the entire territory of the country into territorial constituencies for both. This ensures that representation is based on population, not just geographical area or historical boundaries.
- 2.
The Commission is tasked with defining the boundaries of single-member constituencies. It ensures that each constituency has a population that is as nearly as practicable equal to the population of other constituencies in the same state. For example, if a state has 10 Lok Sabha seats and a population of 1 crore, each constituency should ideally have around 10 lakh people.
- 3.
The Commission considers various factors when redrawing boundaries, including geographical features, the convenience of administration, and the contiguity of areas. However, the overriding principle is population equality. This means that even if a remote hilly area is geographically large, it might have to be merged with another area if its population is significantly lower than the state average, to maintain fairness.

Frequently Asked Questions
121. What's the most common MCQ trap examiners set regarding the Delimitation Commission's basis for delimitation?
The most common trap is assuming the latest census data (e.g., 2011 or 2021) is used. The Delimitation Act, 2002, mandates the use of the 2001 census for determining the allocation of seats and constituency boundaries. While recent exercises, like the one for J&K, used 2001 data, there's a strong debate about using newer census data. Students often incorrectly assume the most recent census is automatically applied.
Exam Tip
Remember: '2001 is the base year for current delimitation, not the latest census.' This is crucial for statement-based MCQs.
2. Why does the Delimitation Commission exist? What problem does it solve that no other mechanism could?
The Delimitation Commission exists to uphold the principle of 'one person, one vote, one value'. After each census, population shifts occur, leading to disparities in the number of voters per constituency. Without delimitation, some voters would have disproportionately more or less electoral weight than others. This commission ensures that constituencies are redrawn to have roughly equal populations, thereby making representation fair and equitable, which legislative bodies alone cannot achieve due to political pressures.
