Interestingly my country (France) shows the same trend, but with a peak almost reaching 50%. It also shows that after that peak, the number of women in IT kept increasing then stagnated, while men exploded: https://imgur.com/a/gNHHIxm https://imgur.com/a/gNHHIxm (rehosted, original website is dead) This might be anecdotal, but I did an engineering school, CS/IT section. It was one of the very first school of my country to have a dedicated CS/IT program and diploma (the section opened over 50 years ago, 40 at the time I was there). A few hundred students each year. One of my teachers was one of the students dating from a few years after the section opened. He told us a few times that when he was studying, each promotion of the section was usually 50% men 50% women, sometimes more women even. When I graduated, it was close to 80% men. The nearby CS focused private school, where one of my friends was going, had 2 women for hundreds of men.
