That stat seems like cap. 78% seems to high.

"Based on data from the 2017 follow-up to the 2016 Baccalaureate and Beyond longitudinal study (B&B:16/17), women represented 53% of Bachelor’s degree recipients in science, engineering and math, 65% of Bachelor’s degree recipients in psychology and other social sciences and 80% of Bachelor’s degree recipients in health and medicine."

"In 2017, 49% of all bachelor’s degrees in science and engineering were awarded to women. This number masks substantial gender disparities across fields, however. Women earned two-thirds of bachelor’s degrees in life sciences, psychology and social science fields — 62% in biology, 78% in psychology, and 61% in social science. In contrast, women were only slightly over one quarter of degree recipients in the combined math-intensive fields of geoscience (39%), engineering (22%), economics (32%), mathematics (42%), computer science (19%), and the physical sciences (40%)."

"With the total number of women in the “architecture and engineering” category at just over 3.6 million, the report from the US Bureau of Labor Statistics further breaks down the numbers. It reveals in greater detail how women are underrepresented comprising::
8.5% of mechanical engineers
17.4% of aerospace engineers
27.9% of chemical engineers
17.1% of civil engineers
15.7% of computer hardware engineers
8.1% of electrical and electronics engineers
25% of industrial engineers, including health and safety
14.9% of all other engineers"
