Shaping Dimensions of Urban Complexity: The Role of Economic Structure and Socio-Demographic Local Contexts

Diversification in urban functions-a key component of urban complexity-was analysed using Pielou's evenness indexes for 12 socioeconomic dimensions (economic structure, working classes, education, demographic structure by age, composition of non-native population by citizenship, distribution of personal incomes, land-use, land imperviousness, building use, vertical profile of buildings, building age, construction materials) at a local spatial scale in the Athens' metropolitan region, Greece. Urban and rural districts were found respectively the most and less diversified contexts, outlining a diversification gradient negatively associated with the distance from Athens. A canonical correlation analysis characterized local contexts with high and low diversification in socioeconomic functions. A spatially-explicit regression model finally demonstrates that local-scale complexity increases with urban concentration, population growth and average per-capita income. A multivariate analysis of individual dimensions of urban complexity is a promising tool to assess socioeconomic transformations in contemporary cities.
