Delimitation: Southern States’ Fears over Lok Sabha Seats
Why in the news
Southern leaders worry that delimitation after the next census could cut their Lok Sabha share, since their states controlled population growth better than northern ones.
Key facts
- Delimitation means redrawing constituency boundaries to reflect population shifts.
- Done three times after independence, on the 1951, 1961 and 1971 censuses.
- In 1976, it was frozen so that states with faster population growth would not gain seats; the 42nd Amendment set a 25-year freeze till 2000, and the 84th Amendment (2001) extended it to 2026.
- Seats now rest on 1971 data: 543 Lok Sabha and 250 Rajya Sabha.
- After the 2001 Census, only boundaries and SC/ST reservations were adjusted, not total seats; another revision is due after 2026.
Seats by census
| Census | Lok Sabha seats | Population | People per seat |
|---|---|---|---|
| 1951 | 494 | 36.1 crore | 7.3 lakh |
| 1961 | 522 | 43.9 crore | 8.4 lakh |
| 1971 | 543 | 54.8 crore | 10.1 lakh |
Concerns
- Tamil Nadu, Kerala, Karnataka and Andhra Pradesh curbed population for decades; Uttar Pradesh and Bihar grew faster, so the south may lose clout.
- Karnataka, Kerala and Tamil Nadu together out-produce the 13 eastern states; fewer seats could hurt central funds.
- Seats by population seem to penalise family planning efforts.
- Simple population-based shifts would favour the north and strain federal balance.
- A delayed census could allow early delimitation that benefits some regions.
Way forward
- Enlarge total Lok Sabha seats to avoid sharp changes in state shares.
- Complete the census with accurate data first; bring policymakers together before the 2026 deadline.
Exam angle
- Amendments: 42nd (1976) and 84th (2001).
- Base census for seats: 1971.
