Yes—delimitation could change how much influence states have in the Lok Sabha, but it does not automatically change their representation in both houses of Parliament.
For the Lok Sabha, delimitation can redraw constituency boundaries and, when seat numbers are reapportioned, change how many MPs each state elects. If some states’ populations have grown faster than others, a future reallocation could shift the balance of Lok Sabha seats between them. The effect would be on each state’s share of the chamber, not necessarily on the total size of the House.
Why seat numbers have been frozen
The Constitution provides for readjustment after a census, but amendments have postponed changes to state-wise seat allocation until the first census taken after 2026. Past delimitation exercises could redraw constituencies without changing the number of Lok Sabha seats allotted to each state. So a new delimitation does not, by itself, mean an immediate shift in states’ seat shares; the timing and rules for any future readjustment depend on the constitutional process and legislation.
Rajya Sabha representation is a separate matter. Delimitation of Lok Sabha constituencies does not redraw Rajya Sabha seats, whose allocation among states is set separately. In short, a future change could affect states’ relative strength in the Lok Sabha, while their Rajya Sabha representation would not change just because of constituency delimitation.
