Proportional Representation
"An electoral system in which the share of seats won by each party closely mirrors its share of the popular vote, unlike first-past-the-post where winner takes all."
Proportional representation (PR) is a family of electoral systems designed to ensure that the composition of a legislature accurately reflects the distribution of voter preferences across the electorate. Under PR, a party that wins 30% of votes should receive approximately 30% of seats — in contrast to First-Past-The-Post (FPTP) systems like India's Lok Sabha elections, where the same 30% of votes might yield far fewer seats if spread across constituencies, or far more if geographically concentrated. The two principal forms of PR are: (1) Party List PR — voters choose parties rather than individual candidates; seats are allocated from ranked party lists in proportion to votes won (used in Israel, Netherlands, South Africa); and (2) Single Transferable Vote (STV) — voters rank candidates in multi-member constituencies; votes transfer to second preferences when a candidate is elected or eliminated (used in Ireland, Malta). India employs PR selectively. The Rajya Sabha and state Legislative Councils use the Single Transferable Vote (STV) method — Members of Parliament or state MLAs vote for Rajya Sabha candidates, and seats are filled proportionally. Presidential and Vice-Presidential elections also use STV with a value-weighted vote. However, the Lok Sabha, all state Legislative Assemblies, and most local body elections use FPTP. The Law Commission of India (170th Report, 1999) examined a shift toward Mixed Member Proportional (MMP) representation — combining FPTP constituency seats with party-list top-up seats — but the recommendation was not adopted. Article 80(4) specifically mandates STV for Rajya Sabha elections.
Tested in GS Paper 2 (Polity — Parliament, elections, electoral reforms). Questions compare PR with FPTP, analyse the representation deficit of women and minorities under FPTP, and discuss whether India should reform its electoral system. The 2024 general election, where the BJP won 240 seats on 36.5% vote share while INC won 99 seats on 21.1% — a highly disproportionate outcome — is a contemporary reference. Also linked to discussions on women's reservation, representation of regional parties, and the 33% women's reservation enacted by the Constitution (106th Amendment) Act, 2023.
- 1 FPTP (India's Lok Sabha system): candidate with most votes wins, even without a majority — leads to manufactured majorities.
- 2 Single Transferable Vote (STV): used for Rajya Sabha, state Legislative Councils, Presidential and VP elections (Article 80(4), 171(4)).
- 3 Party List PR: used in Israel, South Africa, Netherlands — high proportionality but may weaken constituency linkage.
- 4 Law Commission 170th Report (1999): recommended Mixed Member Proportional system for India; not implemented.
- 5 2024 General Election: INDIA alliance won ~40% combined vote share but won ~40% of seats — FPTP amplified BJP's seat share.
- 6 STV formula for Rajya Sabha: quota = (total votes / (seats + 1)) + 1; a candidate reaching this quota is elected.
- 7 Drawback of PR: can lead to coalition fragility and party fragmentation — Israel's experience is a cautionary reference.
The Rajya Sabha election in March 2024 used the Single Transferable Vote method. In states where no single party had enough MLAs to elect all its candidates, cross-voting and strategic preference marking influenced outcomes — notably in Maharashtra and Himachal Pradesh. The STV mechanism ensured that even minority parties in a state assembly could elect at least one representative if they had sufficient combined vote share, demonstrating proportional representation in practice.
