Delimitation & reservation of seats

Story hook

In 1976, at the height of the Emergency, India made a quiet promise to its southern states. The country was running an aggressive family-planning drive, and a worry had surfaced: if Lok Sabha seats were always redrawn by population, then the states that succeeded in controlling their numbers would lose seats to the states that did not. Good behaviour would be punished with less power.

So the 42nd Amendment (1976) hit pause. It froze the allocation of Lok Sabha seats among the states — locking them to the 1971 census — so that no state would lose parliamentary weight for curbing its population. The freeze was meant to last until 2000; in 2001 the 84th Amendment extended it again, to "the first census taken after 2026."

That date is now upon us. When the freeze lifts, India must finally redraw the size of the Lok Sabha by today's population — and the populous north (UP, Bihar, MP, Rajasthan) stands to gain seats while the south (which controlled its population earliest) stands to lose relative weight. Layered on top is the 2023 women's reservation law, which itself kicks in only after this delimitation. Delimitation — a dry word about drawing constituency lines — has quietly become the single most explosive federal question of the decade.

Why this matters for UPSC

A high-yield, fast-rising GS-II topic. Prelims tests Article 82, the reservation articles 330-334, the Delimitation Commission (its orders can't be challenged in court — Art 329), and the seat-freeze amendments (42nd, 84th, 87th). Mains and interviews now treat "delimitation after 2026" as a flagship federalism problem, tied to the 106th Amendment (women's reservation) and the North-South debate. Few topics connect so many current-affairs threads.
