The Government of India has constituted four Delimitation Commissions since independence, with the first two established in 1952 and 1963, focusing on delineating electoral boundaries for legislative bodies. These commissions play a crucial role in redrawing constituencies based on population changes, ensuring fair representation in the democratic process. The last two commissions, set up in 2002 and 2020, aimed to accommodate population growth and changes, which are significant topics in the context of electoral legislation and constitutional mandates covered extensively in UPSC-level resources, emphasizing the importance of maintaining equity in political representation.
