The aim of this paper is to inform urban design practice through deeper understanding and analysis of the social dynamics of public outdoor space in ethnically diverse neighbourhoods. We hypothesise that findings from ethnographic research can provide a resource that improves cultural literacy and supports social justice in professional practice. The primary method is a meta-synthesis literature review of 24 ethnographic research papers, all of which explore some dimensions of public open space use and values in UK urban contexts characterised by ethnic and racial diversity. We summarise thematic understandings and significance of neighbourhood places of shared activity, parks, spaces of passing-by and of retreat. We evaluate the implications for intercultural social dynamics, exploring the spatial and temporal dimensions of conviviality and racism in public open space. We then argue that it is possible to develop principles for urban design practice informed by this work, and propose four for discussion: maximising straightforward participation, legitimising diversity of activity, designing in micro-retreats of nearby quietness and addressing structural inequalities of open space provision. We conclude that ethnographic research can provide detailed insights into the use of the public realm and also inform a more nuanced understanding of outdoor sociality relevant for an increasingly diverse society. The challenge is two-fold: for ethnographers to become less cautious in engaging with decisions and priorities regarding how cities change, and for urban designers to explicitly embed informed understandings of difference into their broad desire for inclusive public space. ARTICLE HISTORY

This paper presents findings from a mixed-method research project which explored use of outdoor spaces and social connections in Bradford, a post-industrial city in the north of England with a highly ethnically diverse population. Data was collected through micro-scale behavioural mapping of public spaces (analysed using GIS), and both on-site and in-depth interviews. The integration of these methods allows a focus on intersectional identities and social values for everyday conviviality situated in different typologies of public open spaces (parks, squares, streets) in city centre and suburban neighbourhoods. The analysis offers nuanced insights into the socio-spatial aspects of conviviality: patterns of activity by diverse users, situations in which encounters are prompted, and the implications of negotiating differences in relation to perceptions of self, others and the environment. We discuss the relevance of the urban public realm for shared understandings of diversity, qualities of visibility, lingering and playfulness, and the importance of threshold spaces. We discuss racialised and excluding experiences and how these relate to mobility and territorial patterns of use, specifically with relation to gender. The paper highlights the connections between findings on intercultural encounters with urban design practice, with implications for wellbeing and integration in ethnically diverse urban areas.
