概要	The key-informant interview is a purposive in-depth interviewing technique in which the ethnographer works closely with a small number of especially knowledgeable or well-positioned community members rather than a representative sample. Key informants are people who, by experience, role, or position, can articulate cultural knowledge a typical member could not. The method centers on selecting such people well, building genuine rapport, eliciting their expertise through ethnographic questioning, and cross-checking what they say against other informants and observations to guard against bias.	The life-history interview is an ethnographic interviewing technique in which the researcher elicits one person's whole life, told chronologically, usually across several extended sessions. The narrator recounts childhood, family, work, migration, turning points, and old age in their own words, and the resulting narrative is treated as both ethnographic and historical data. Analysis proceeds thematically — coding recurring topics and meanings — and narratively — attending to how the story is constructed, sequenced, and given significance by the teller.
