I really wish they would quit promulgating this because it's actually counterproductive: "women face continued pay disparity" Seeing this statement tells me immediately that the author is grinding an ax. In some fields of engineering (EE, for example), women actually get paid more (104% last I checked). And, when you control for experience, time off for family, etc., pay disparities in most tech fields almost disappe…
Based on my casual research, the correct answer to "what's the gender pay gap" is to sidetrack into a half-hour discussion on what you're controlling for and whether it's appropriate to control for that.
For example, professions where flexible schedules are rare see the wage gap grow for women between their 20s and 30s (compared to professions where flexible schedules are more common). This is likely because that's around the age where people have children and women are expected to handle a disproportionate measure of childrearing duties.
Is that something you try to control for? If you're looking for direct, hiring-manager-discriminating-against-you sexism, then yes, you control for it. If you're looking for the wide variety of subtle ways women are discriminated against, you don't.
From what I've found, if you're looking for the sort of direct sexism of hiring managers paying less to _exactly_ the same person for _exactly_ the same work, you come out with a 3-10% wage gap.
If, on the other hand, you're looking for the wide variety of systematic ways women are prevented from getting equal pay, you get 10-30%. Some of those ways can be addressed at the individual level, some at the company level, and some at the societal level.
