概要	Comparative oral history collects and systematically compares first-person spoken testimonies from two or more distinct groups, communities, or historical contexts. The method blends the interpretive depth of oral history — privileging personal memory and narrative — with the analytical logic of comparative design, enabling researchers to identify both shared patterns and meaningful differences across the groups under study.	Comparative biographical research is a qualitative design that gathers in-depth life-story accounts from multiple participants and systematically compares them to identify structural patterns, commonalities, and divergences across individual biographies. Rooted in the sociological life-history tradition, it moves beyond single-case description to generate broader theoretical insights about how social conditions, historical contexts, and personal agency shape individual trajectories.
