In this paper we unpack how geographers have studied institutions, focusing specifically on institutional ethnography, often called ‘IE’. Sociologist Dorothy Smith is widely credited with developing institutional ethnography as an ‘embodied’ feminist approach. Smith studies the experiences of women in daily life, and the complex social relations in which these are embedded. Institutional ethnography offers the possibility to study up to understand the differential effects of institutions within and beyond institutional spaces and associated productions of subjectivities and material inequalities. We suggest that geographical scholarship on institutions can be enhanced and, in turn, has much to contribute to the broader interdisciplinary field on institutional ethnography, such as understandings of institutions that account for spatial differentiation. We argue that IE holds potential to enrich geographical research not only about a multitude of kinds of institutions, but about the many structures, effects, and identities working through institutions as territorial forces. In spite of recent interest by geographers, the broader literature on institutional ethnography remains under-engaged and under-cited by human geographers. Critical of this lack of engagement, we suggest that it has left a gap in geographical research on institutions. Our aim is to analyze and advance existing scholarship and offer this article as a tool for geographers thinking about employing IE. We develop a typology, categorized by methodological approach, to highlight ethnographic approaches to institutions undertaken by geographers. [ABSTRACT FROM AUTHOR]
