Korea is quite well-known for having one of the highest gender wage gaps among advanced countries and there's even more data supporting this.
Business rating agency CEO Score's recent survey on Korea' top 290 companies show,... that men earn 23-thousand dollars more a year than women.
The average annual salary for men last year was 64-thousand dollars, while women earned 41-thousand.
The gender wage gap was the widest in the banking sector, where the difference was 40-thousand dollars.
The agency said the reason is mainly because men stay with their job longer than women... and also because women tend to stay longer in lower positions.
