1971 South Korean legislative election

Legislative elections were held in South Korea on 25 May 1971. The result was a victory for the Democratic Republican Party, which won 113 of the 204 seats in the National Assembly. Voter turnout was 73.2%.

Electoral system

The unicameral National Assembly was elected by parallel voting, with 153 legislators elected in single-member constituencies and 51 allocated via a modified formula on the national level, excluding parties that did not win more than three seats or more than 5% of the valid vote. If the percentage of votes for the first-placed party was over 50%, the national seats would be allocated in proportion to vote share, with the first-placed party being limited to two-thirds of the available national seats. When the number of votes of the top party was less than 50%, half of the seats in the national constituency were automatically allocated to the first-placed party, and the process repeated for the remaining parties until all remaining seats were allocated.
