The World Econ Forum ranked "countries by the gender gap between men and women from a report by the World Economic Forum, based in Geneva. The countries are ranked in four areas: economic participation, education attainment, health and survival, and political empowerment."
Sri Lanka is #16 while the U.S. is #19. Interesting! The highest possible rank is 100 -- it looks like Sri Lanka's women do excellently well in economics and do a bit more than half as well as the men in education.
overall %: 74.58%
economic participation: 89
educational attainment: 57
health and survival: 1
political empowerment: 6
[later note: as Jed pointed out in comments, I totally got confused about the rankings -- 1 is top, 100 is bottom. So reverse my commentary below.]
But pretty awful in politics and horribly in health and survival. Sigh. I guess if you manage to survive, you have a decent shot at doing okay financially.
I admit that I'm surprised that American women are lagging so far behind American men in education -- I had thought that we were approaching parity at the college level. I'm not sure how to make sense of that statistic. (a score of 1, almost complete inequality)
