Despite the recent significance children's geographies have been afforded within many geographical subdisciplines, their experiences of migration have received relatively little attention. However, children do migrate and their migration is often distinct from that of entire households. In this paper we explore children's migration in southern Africa within the context of the HIV/AIDS pandemic, focusing in particular on the impacts of moving house on children's sociospatial experiences. Migration has consequences for several areas of children's lives, and the nature of those consequences is shaped by the context within which migration takes place. In southern Africa AIDS is an unavoidable aspect of the sociospatial context, but the impact it has on children varies. This exemplar has wider implications for two areas of geographical research. First, in the paper we advocate the importance of including children's experiences of migration within culturally informed studies of migration. Second, there is a need for research in children's geographies to extend beyond the microlevel. We advocate a refocusing of research beyond children's static relationship to environments to also encompass children's transient geographies in discussions of their life experiences.
