I've commented before on how the World Economic Forum's Global Gender Gap Report is useless for actually determining a gender gap, and a recent article has pointed out some absurdities in the latest version of the index (emphasis mine):
The countries which are ranked highest in each category are not those which have the smallest gender gap, but those which have the largest “reverse” gender gap.
When measuring enrollment in tertiary education (college, university etc) this produces some bizarre results. The number one ranking nation is Qatar with a staggering female to male student ratio of 5.60. The US comes in at 32nd place with a ratio of 1.41, while the UK is 36th with a ratio of 1.38. Over half of the countries surveyed have more female than male students. Apart from suggesting that the term “reverse gender gap” may be a misnomer in this particular area, it also means that those countries which currently have a perfect 1.00 ratio (Switzerland and Guatemala) are relegated to the bottom half of the table. Beneath these are the minority of countries which have more male than female students, with Chad being at the very bottom of the pile with a dismal ratio of only 1 female student for every 4 males.
Perhaps the oddest thing about this whole odd table is that the size of the gender gap in the worst country is surpassed only by the size of the gender gap in the “best.”
