"POROUS EUROPE: EUROPEAN CITIES IN GLOBAL URBAN ARENAS"

The notion that there is a European 'system of cities' or 'urban hierarchy' has been an attractive idea, since it appears to provide a coherent subset of cities to study within a regional context. Under conditions of contemporary globalisation, however, the spatial order of European cities can only be properly understood as a 'porous Europe'. That is, it is impossible to sensibly discuss European intercity relations separate from an encompassing world city network. This paper therefore analyses 88 European cities in the context of a global urban analysis of 234 cities around the world. The main conclusion is that leading European world cities are specifically distinguished through their forming of global urban arenas. They should therefore not be thought of as being un-European, but as a special kind of world city that is highly cosmopolitan in its intercity relations.

Megalopolis 50 Years On: The Transformation of a City Region

This article examines Megalopolis 50 years after Gottmann's seminal study of the most urbanized region of the US Eastern Seaboard. His study provides an invaluable datum point, and we use it as a benchmark for reexamining the socio-spatial transformations of a city region. After redefining Megalopolis and showing major aggregate trends since 1950, we analyze 39 selected variables for place level census data for 2,353 places to perform a principal components analysis (PCA). Our analysis shows that Megalopolis remains a significant center for the nation's population and economic activity. A half century of urban restructuring demonstrates that the forces of urban decentralization have made the region a more fully suburbanized agglomeration. We reveal a complex socioeconomic pattern of a vast urban area structured by class, education, housing tenure, housing age, and race and ethnicity. The cluster analysis reveals five distinct clusters of urban places identified by our PCA: 'affluent places', 'places of poverty', 'Black middle class places', 'immigrant gateway places' and 'middle America places'.
