The paper explores children’s role as reproducers and transformers of residential power positions in the city, by investigating how children relate to, use and rework positions and identities offered to them and others. The paper argues that children are engaged in various kinds of politics in which they have their own positions and roles. Politics is understood as children practicing politics in their seemingly apolitical everyday environments (Kallio and Häkli, 2011), and the politics is located to their efforts to negotiate structures, relations and identifications through spatial practices, contestation, critical perceptions and judgements about inequality and difference (Elwood and Mitchell, 2012). The results are based on two studies, one mapping children’s understanding of social relations through their experiences and perceptions of places in the city, and another based on interviews with parents and children. Both studies are part of a larger study aimed to explore social relations in a city, which during the past decade has undergone major demographic changes. Based on the results, it is argued that children play a key role in the reproduction of difference, and therefore in the reproduction of uneven power positions in the residential figuration in the city. It is also argued that there is a need to recognize, as Valentine (2003) points out, that childhoods are bound up with wider geographies and structures such as class, race, gender, and sexuality. Structures that children use for differentiation and positioning.
