The differences are very small, and I am not too surprised with the relative popularity of Matlab and R compared to say Haskell, since there are relatively more women majoring in engineering that computer science, as well as relatively high numbers doing quantitative work in the social sciences. I wonder why Rust, though, is such a huge outlier. Maybe it is just noisy because there are so few people asking about Rust at all on Stack Overflow.

From the link, the women surveyed skewed towards being more junior/less experienced. And Rust is not exactly a language that skews towards junior developers, due to its high learning curve. I bet Rust would be less of an outlier if one controlled for level of experience.
