Abstract. In the paper patterns of social interaction are examined, as shaped by an inflow of new residents to an inner-city subarea characterized by a low socio-economic status and featuring ethnic homogeneity. The empirical material is derived from a set of semi-structured interviews conducted by the authors with the area's inhabitants, and with representatives of local governance arrangement and initiatives. The analysis is based on the concepts of social hyper-diversity, social networks, the concept of place and the research on gentrification. Sub-categories of residents are distinguished by referring to both functional and emotional types of social relations they enter into. The findings point at the formation of networks of integrative nature, mostly such that are supported by the use of common urban space, across the social categories identified, but also to limits and obstacles to social integration, both general and those specific to the case study area.
