Throughout this volume, the two leading questions had been: How does urban space structure the life of ethnic groups? How does ethnic diversity contribute to creating an urban shape or give shape to a particular space? In spite of the fact that we do not claim to have provided completely satisfying answers to these questions, we feel that we can still pull together the threads that have come out. Hence, this chapter consists of empirical generalizations based on the case studies given previously, supplemented with additional relevant literature. Taking the limited number of cases into account, every conclusion must remain preliminary. The points are presented as hypotheses to be tested rather than as the final word on an issue. Having included cases from countries other than North America and Western Europe, we hope that the range of possible relationships between urban space and ethnicity has been widened enough to stimulate further research.
