Purpose: The purpose of this study is to provide a global snapshot of the current state of knowledge regarding attrition rates of women architects. The intended audience includes all the stakeholders of the profession, as well as those interested in professional attrition studies, with the aim to contribute to a social debate, which places increasing value on diversity, equal representation and retention in this field. Design/methodology/approach: This paper has utilized the structured analytical technique of a systematic review of the scholarship involving scholarship published over two decades between the years 2000 and 2020. Having selected research on this topic following a series of exclusionary and inclusionary criteria for relevancy and accuracy, this select research has been categorically and thoroughly analyzed using this technique. Findings: This literature review identifies four main recurring themes among the literature, which address this research question, including: (1). cross-national differences and similarities; (2) demotivating factors leading to attrition; (3) graduate/architect terminology, which blurs the distinction between participants in architecture; and (4) implications of female architects as represented in professional publications and the “reward system.” Consequently, this literature review finds that to date no singular cause can be pinpointed as the sole cause of women's attrition, but rather a series of complex and intertwining factors, some of them specific to the profession. Originality/value: This paper suggests areas for further study into the reduction of attrition rates of registered women in this discipline, with an emphasis that further research may expand to focus rather on positive aspects of the profession resulting in areas of retention, which has been of little focus in current research. Additionally, these findings make suggestions toward a series of recommendations that may assist in framing the industry toward more positive and equitable career and industry trajectories.
