Women now earn what men did a decade ago, according the most recent Global Gender Gap Report 2015.
The report by the World Economic Forum (WEF), which looked at 145 countries, found that the economic gap between the genders will take 118 years to close at the current rate of progress.
In some other measures of inequality the gap between genders has widened since 2006, such as literacy rates and educational attainment in nearly a quarter of the countries surveyed.
The UK was 18th overall in terms of gender equality, with a score of 0.758, while Iceland took the top spot with a score of 0.881.
The result saw a slight upturn from last year's ranking of 26, after several years of continued decline.
Particularly poor was the UK’s ratio of women in ministerial positions compared to men, 0.29, placing the country 50th on the index.
Here's how the UK performed in some of the other assessed criteria:
Labour force participation:
Healthy life expectancy:
