This article deals with the politicised notions of trust and social cohesion in urban spaces through a focus on practices of everyday relations in a mixed neighbourhood. Quantitative studies maintain that ethnically diverse neighbourhoods lack in trust and solidarity. However, the very meaning and effect of concepts such as `diversity`, `contact` and `trust´ are often unclear. This article challenges both the politicised assumptions and methodological basis for statements on trust as a condition for coexistence. Drawing on fieldwork in a multi-ethnic social housing estate in Copenhagen, this article explores residents´ understandings of diversity, contact and trust. The article argues that trust and strong ties may not be the prerequisite for coexistence in neighbourhoods, where the micro-politics of everyday contacts predominate.
