The bar charts compare the proportion of male and female students choosing different science subjects — biology, physics, and computer science — at a university in 1992 and 2012.
Overall, male students consistently outnumbered females across all science disciplines, although the gender gap narrowed over the period. While the popularity of biology and physics declined, computer science became increasingly favored by students.
In 1992, 65% of students enrolled in biology were male, while only 32% were female. By 2012, the proportion of male biology students dropped to 50%, whereas female participation rose to 45%, indicating a narrowing gender gap.
Regarding individual subjects, biology was the most chosen in 1992, accounting for 65% of enrollments, followed by physics (23%) and computer science (3%). However, in 2012, biology and physics saw slight decreases to 41% and 20% respectively, while computer science saw a significant increase to 25%.
