Research has established the importance of including demographic considerations in organizational analysis to provide a more comprehensive explanation of organizational phenomena. However, there are a wide variety of conceptual and empirical perspectives in the field of organizational demography. Each perspective has a different focus and conceptual underpinnings. In this paper, we develop a framework to categorize the current literature into cohesive theoretical perspectives. In addition to organizing the past and current work in the field, the framework draws attention to other possible approaches to demographic research in organizations.
