With my stats hat on, what on earth is this paragraph trying to say?
Last week in the UK, headlines declared that women in London earn 13 per cent less than men and that the pay gap is widening. Not only do such claims not stand up to scrutiny – even worse, they actually hide a far more positive story about women’s pay […] For women up to the age of 40, median hourly earnings rose faster than for people in any other group, increasing by 81.7 per cent, and as a result the pay gap for this cohort went down from 25.1 per cent to 12 per cent.
The pay gap of 13% doesn't stand up to scrutiny because in women under 40 the pay gap is now 12%?!
Actually, I think it's true that in some circumstances in some industries the pay gap is no longer there (particularly early career), but it definitely widens as you get more senior, and definitely once kids are involved.
