Investment in education and social welfare, combined with time.

My university is growing into having a more balanced faculty mainly because it is now seeing an increasing number of female candidates. This is a result of the study (economics and finance) becoming more popular in the past two decades with women, and we are seeing the results only now. There will always be lagged effects in this.

Granted, there are quotas in place too.

Except that poorer countries that invest less in social welfare tend to feature more gender balance than advanced countries. Because preference and aptitude matters a lot; male and female folks simply tend to care about different things.
