Iraq, Syria, Pakistan and Yemen showed the biggest overall gender gaps of the countries surveyed in 2018 by the World Economic Forum.
The WEF's report published on Tuesday indicates it will take centuries to achieve gender parity in workplaces around the globe. However, the report said that while there had been some improvements in wage equality this year compared to 2017, there was still about a 50-percent difference in salaries.
At current rates, the global gender gap across a range of areas will not close for another 108 years, while it is expected to take 202 years to close the workplace gap, the WEF found.
The report, which was based on data from 149 countries, addressed four areas: health, education, work and politics.
