Anecdotally, the biological engineering department at my university has a much higher fraction of women than the rest of the college of engineering, while mechanical/aerospace has the lowest, so it varies even within engineering.

I’ve heard this kit is really good! As a Full Mechanics kit, it’s not a proper MG, though: same scale but design standards are closer to an HG. The external detail is comparable to a MG, but they lack the inner frames typical of MG kits. Unless it’s an IBO Full Mechanics kit, which do have a frame, but instead have lower overall detail. It’s kind of convoluted and they’re just “The less expensive and easier to design 1/100 kits”
