Ethnographic methods have an important role to play in the development and confirmation of sociological theory, as well as the discovery of anomalies and new domains of empirical research. The Princeton Sociology department includes a critical mass of prominent scholars engaged in this approach, making it a leading center of sociological ethnography. Princeton's ethnographers join with their compatriots in other universities in Serving as ambassadors of sociology to the wider public through enduring books of interest to students, laymen, and policy makers. Although many ethnographic studies have focused on life in cities, ethnographers also study rural villages, suburban communities, families, and business firms and nonprofit organizations. The ethnography cluster offers a year-long training course composed of four mini-seminars: The Ethnographic Tradition; The Logic of Inquiry in Ethnographic Research; Fieldwork Methods; and Ethnographic Analysis and Writing.
