Segregation is a central concept in the debate on urban issues, both in scientific literature and in society in general. The process of globalisation is particularly expected to increase polarisation and segregation in cities, resulting in the emergence of 'ghettos' or - as they are called in the Netherlands - 'income neighbourhoods'. This paper tries to judge the situation in Dutch cities by studying changes over time; by looking at segregation within cities as well as between cities and the wider metropolitan area; and by comparing socio-economic differences with socio-cultural and socio-demographic characteristics. The analysis shows that the empirical facts are quite different from the ongoing debate. It establishes that socio-economic segregation is more moderate than segregation with respect to the other two dimensions. Contrary to suggestions from the vernacular debate, segregation within cities is scarcely increasing, but between cities and the surrounding area it is rising with respect to all three dimensions.
