India has an equal ratio in CS, still looking for CE. The ratio is explained as follow >Limited Career Choice in India: Among families who send their children to university in India, engineering or medicine is the default expectation (both for men and women). Parents place great pressure on their children to study specific subjects for reasons of socio-economic prospects –career and marriage partners are a prime concern. For the most part, children feel they must comply. http://www.hcixb.org/papers_2017/hcixb17-final-37.pdf
That seems to be a general trend, the less pressure, the worse the ratios. https://www.theatlantic.com/science/archive/2018/02/the-more...
