The equality gap between men and women would take 100 years to close at its current rate, an economic monitoring group has suggested, reports BBC.
It is the first time that data from the World Economic Forum (WEF) has shown a year-on-year worsening of the gender gap since it began charting it in 2006.
The report ranks 144 countries by economic opportunities, education, political participation and health.
Women are measured as having 68 percent of the chances and outcomes that men have.
This is slightly down from the 68.3 percent measured last year.
The group predicts that it would a century to close all areas of equality it monitors globally, well up from the 83 years predicted in 2016.
Gender parity is closest in areas of health and education, it says, but significant gaps in economic participation and political empowerment continue to endure across the world.
Women will have to wait 217 years before they earn as much as men and are equally represented in the workplace, the figures suggest.
Nordic countries remain among some of the world’s best for overall equality. Iceland tops the list with a 12percent gender gap across all the WEF’s measures. Norway, Finland ands Sweden are all in the top five.
Rwanda came fourth in the list for overall gender equality with a gap of 18percent. The country has the highest share of women in parliament in the world - they occupy three in every five seats.
Nicaragua, Slovenia, Ireland, New Zealand and the Philippines also made the top 10 on the Global Gender Gap rankings.
Women in the Middle East and North Africa fared the worst, with war-torn Yemen coming last on the list with a gender equality score of just 52percent.
The report shows women in the world earn less not just because of gendered salary differences, but because women are more likely to do unpaid or part-time work than men.
Women also generally tend to work in lower-paid professions and are less likely to be in highly-paid senior roles in companies.
Slovenia has the smallest gap in gender earnings - with women there on average earning 80.5percent of the male national average.
Both Canada and France saw improvements to their political empowerment measures after Justin Trudeau and Emmanuel Macron added more women in ministerial positions within their governments. The US saw a marked drop in this area, with female political empowerment at its lowest rate in 10 years. It came 96th in this area.
The report blames a significant decrease in female ministerial positions for the fall - a Freedom of Information request in March revealed that only 27percent of all jobs within the Trump administration were taken by women.
