Your link is quite interesting especially for the economic part. Not only but this part should be as relevant for chess as for go.
Quote from that article written by a woman chess player:
It’s not just lack of encouragement, though. It’s time. It’s priorities. It’s well-established that women do the bulk of the housework, for example. A 2016 analysis carried out by the UK Office for National Statistics finds that women carry out 60% more unpaid work. A 2019 study led by McMunn reached similar conclusions: women performed 16 hours of unpaid labour per week, and men only performed six. In 93% of couples surveyed, women did the majority of the work. The gap remains even when women are employed more gainfully than their husbands: a 2014 study led by Besen-Cassino concludes that the more a woman earns, the less housework her husband does.
This gap in unpaid labour starts early. Lam et al. (2016) discovered that young girls do more chores than young boys, and when mothers spent longer hours away from the home, the girls took on most of the extra work. UNICEF reports that girls, on average, perform 40% more chores. It’s clear to see the disadvantage girls and women are at, here. A disproportionate lack of free time will obviously contribute to lower chess achievement.
