Final answer:
Cultural factors, gender stereotypes, and lack of mentorship contribute to the low representation of women in CEO positions in Fortune 500 companies, despite a gradual increase to 8% in 2021.
Step-by-step explanation:
When exploring the diversity of executive teams within Fortune 500 companies, it's clear that there's been a historical challenge for women to break the 'glass ceiling' and achieve roles as CEOs. Past evidence suggests that cultural factors related to gender roles and child-rearing impact the chances of women ascending to top business positions. Additionally, stereotypes about women not being aggressive enough for the boardroom, a lack of mentorship, and rooting in traditional gender biased roles contribute to the disparity. Despite these barriers, it seems that progress is being made slowly, with the number of female CEOs in Fortune 500 companies witnessing a rise to 41 in 2021, approximately 8%.
