Tóm tắt	Multiple case-based biographical research combines the cross-case replication logic of multiple case study design with the in-depth life-history orientation of biographical research. Each individual biography is treated as a bounded case, examined first on its own terms, and then analysed comparatively across cases to identify patterns, contrasts, and transferable insights about how lives are shaped by social, historical, and structural forces.	Biographical research is a qualitative method that examines individual lives in depth — through life-history interviews, personal documents, letters, and autobiographical narratives — to understand how personal experience intersects with social, historical, and cultural forces. Rooted in Wilhelm Dilthey's hermeneutics and made prominent in sociology by Thomas and Znaniecki's study of Polish immigrants, it treats the individual life story as a window onto broader social structures and processes. It belongs to the narrative inquiry subfamily alongside oral history and life-story research.
