Gender-inequality issues extend beyond wages. When you add in other factors, like educational attainment, opportunities, and health, the rankings look a bit different.
For that context, check out the World Economic Forum's Global Gender Gap Index, which ranked 144 United Nations member countries on gender equality using wage data, level of education, economic participation and opportunity, health, and political empowerment.
Of the countries on that list, not one broke the 0.9 mark (out of the highest possible score of 1) and only five countries scored 0.8 or higher, based on OECD's findings. The highest ranked country, Iceland, scored 0.874 in 2016, while the US (0.722) ranked 45th.
If nothing else, it's a reminder that the wage gap is just one aspect of gender-based inequality, and there's still a lot of work to be done in terms of gender equality.
