Critics label as ‘absurd’ idea from government-backed thinktank as country seeks to address population decline

A government thinktank in South Korea has sparked anger after suggesting that girls start primary school a year earlier than boys because the measure could raise the country’s low birthrate.

A report by analysts at the Korea Institute of Public Finance said creating a one-year age gap between girls and boys at school would make them more attractive to each other by the time they reached marriageable age.

The claim is based on the idea that men are naturally attracted to younger women because men mature more slowly. Those women, in theory, would prefer to marry older men.
