As a student, how do I simply understand how gender is presented in "An Inspector Calls"?

The most basic way to understand the presentation of gender in "An Inspector Calls" is to acknowledge JB Priestly's employment of distinct dramatic choice in having three women central to the plot of the play. These women distinctly represent the three different attitudes towards gender that are prevalent in the text. Mrs Birling is visibly the eldest female character on stage. She symbolises traditionalism and the older generation's conformity to typical gender roles. She advocates marriage for social elevation and holds conservative opinions about the role of a wives and mothers. Eva Smith represents the initial idealism of the younger generation. She symbolises a desire for both social and financial liberation, but is a victim of her circumstances due to traditionalist such as the Birling elders. Her inability to succeed illustrates the lack of social progression unless every individual acknowledges the need for change. Sheila Birling represents the younger audience and has strong parallels to Priestly himself. She begins conforming to traditionalism, yet by the end of the play succumbs to the ideals of the Inspector, reconsidering her own morality and social responsibility. She serves as a reminder of the historical context in which the play was created, when there was a cultural shift in attitudes towards gender after women proved themselves competent in industry during the Second World War. She conveys the gradual shift towards socialism in Britain, and attempts at multiple times to reconcile the traditionalist and liberal ideas within her family. If we acknowledge the role that the presentation of the women serves in the wider narrative, we can understand how the theme of gender is linked to the wider significant idea of social evolution.
