In the last decade the U.K. has witnessed a rapid change in the pattern of ethnicity within its population, with substantial increases in the percentage of young people from black and minority ethnic (BME) backgrounds and, in particular, from mixed-race families (Platts 2009). If current trends continue, ethnic minorities and those from mixed race backgrounds will make up an increasingly large proportion of the population in the future. These dramatic demographic transitions present challenges in how urban design can meet the diverse needs of multi-ethnic communities and – the focus of this paper – sustain health and well-being. It is known that deprived and BME groups suffer from health and environmental inequalities, and recent research has indicated this also extends to poorer access to urban green space (Comber et al 2008). It has also been shown that access to urban green space can help reduce health inequalities between deprived and wealthier communities (Mitchell and Popham 2008) but, as yet, there is little evidence on how quality of urban green space affects well-being and health in BME groups living in deprived, urban communities. This study (commissioned by the Commission for Architecture and the Built Environment – CABE Space) explored the quality and availability of green space in deprived, multi-ethnic communities in key urban areas in England, and the relationship between urban green space and well-being for both white majority and BME groups. Methods included focus groups, environmental quality audits and a household questionnaire survey (n=523). Six case study areas were chosen using English national level data on deprivation, ethnicity, etc., to identify urban locations where the population fell within the most deprived 20% of neighbourhoods, with substantial proportions of minority ethnic groups, and where local authority performance criteria indicated varying quality of green space, so that contrasting communities with good or with poor quality green space provision, could be compared. Findings from the questionnaire survey will be presented in two parts. Firstly, results will show how the relationship between green space and well-being compares to other environmental factors (such as air pollution, access to shops, etc) using a preference simulator to show results from adaptive conjoint analysis. Secondly, using a range of statistical methods, we will report on well-being in relation to current use of green space, perceived quality of green space and potential interventions that might change behaviour in relation to well-being. The results will explore how patterns and preferences between groups, including BME groups, differ and how these results sit within the context of findings from the focus groups and environmental audits. Finally, we will discuss the implications of this research for recreational and social policy in the U.K. and Europe.
