The number of unemployed college graduates in Korea hit a five-year high in the second quarter amid a tightening job market for young adults, government data showed Sunday.

The number of jobless people with a bachelor's degree and above reached 481,000 in the April-June period, up 39,000 from a year earlier, according to the Ministry of Data and Statistics.

The figure marked the highest second-quarter level since 2021, when 521,000 graduates were out of work during the COVID-19 pandemic.

Those in their 20s and 30s accounted for 64.2 percent of all unemployed people with a college degree or higher, with a combined figure of 309,000.
