A new study has been released to mark International Women's Day.
It shows women's participation in economic activities could be a means to lessen the old-age dependency ratio.
The ratio refers to the number of people 65 and over as a share of the working population.
The report from the Federation of Korean Industries shows women's economic participation rate in some 20 out of 23 countries that have lower old-age dependency ratios, exceeded the OECD average of 65 percent in 2019.
It also said that women's economic participation raises a country's birth rate as seen in countries such as Britain, Germany and Sweden.
