The household is a ubiquitous unit of analysis across the social sciences. In policy, research and practice, households are often considered a link between individuals and the structures that they interact with on a daily basis. Yet, researchers often take the household for granted as something that means the same thing to everyone across contexts. As the household has never truly been a static unit of analysis, we need to revisit the household to ensure that we are still capturing what it means to be part of a household – especially if we are engaging in research where we aim to compare households across time and space. We analyse how the concept of the household has been used over time and identify areas, such as migration and urbanisation, where we need to ensure conceptual clarity. We use our field notes and ethnographic interviews to show the challenges of such an analysis.
