সারসংক্ষেপ	Field-based life history research is a qualitative design that combines sustained ethnographic fieldwork with in-depth biographical interviewing to reconstruct how individuals have experienced and given meaning to their lives within particular social, cultural, and historical contexts. Unlike archive-only biographical work, the field-based variant requires the researcher to be physically present in the participant's social world over time, gathering both spoken life stories and observational data from that world.	Ethnography is a qualitative research tradition in which a researcher immerses themselves in a social group or community over an extended period — typically three to six months or longer — to study its culture, values, and behaviours in their natural setting. Originating in social and cultural anthropology, and consolidated as a rigorous method by Bronisław Malinowski in the early twentieth century, ethnography produces rich, contextualised accounts of how people live, work, and make meaning together.
