Why women are underrepresented in certain careers has been a pertinent question for career researchers and scholars interested in gender equality issues for decades. Researchers have been particularly interested in the lack of women in science, engineering, and technology careers, as well as those with high mathematics content. Throughout this book, the authors have highlighted why gendered occupational segregation is an issue for both gender equality and essential in addressing the skills shortage in some occupations. They have aimed to give readers an overview of key areas to consider in assessing gendered occupational segregation. Importantly, the authors wanted to highlight the multifaceted variables involved in perpetuating and reinforcing gendered occupational segregation, especially for women in science, engineering, and technology careers. They have demonstrated how a multiplicity of interacting influences shape women’s careers. In particular, this book has emphasised the role of psychological, organizational, and social factors in understanding career roles and trajectories. Many books have looked at women’s underrepresentation in the ICT and SET industries; however, this book has taken into account not only these male dominated industries but has also included other male dominated industries such as construction, and the new industry of computer games, in order to understand the reasons behind this underrepresentation.
