สรุป	Comparative life history research is a qualitative approach that collects extended first-person accounts of individuals' lives across two or more cases, groups, or social contexts, then systematically compares these accounts to identify shared patterns, divergences, and the social forces that shape biographical trajectories. It bridges the depth of life history with the analytical leverage of cross-case comparison, making it especially powerful for understanding how social structure, culture, or institutional context shapes individual experience over time.	Comparative case study is a qualitative research design in which two or more bounded cases are studied in depth and then systematically compared to identify similarities, differences, and patterns across contexts. Rooted in Yin's replication logic and Stake's multiple case framework, it is particularly suited to questions that ask how or why a phenomenon unfolds differently — or similarly — across distinct settings, populations, or time periods.
