Changes in spatial patterns of the immigrant population of a southern European metropolis: the case of the Barcelona Metropolitan Area (2001–2008)

Abstract

To date, the evolution of residential segregation patterns in southern European cities has received little attention. The case of Barcelona metropolitan area (BMA) is particularly relevant following a rapid growth of immigrant population over a very short period. This empirical study seeks to see if this rapid growth has changed the spatial segregation patterns of immigrant groups and led to the emergence of ethnic enclaves. First, we calculate five indices according to the classic dimensions of residential segregation. Then, we use an adapted version of the Poulsen et al. typology in order to identify ethnic enclaves. In the period under study, there was a general increase in two dimensions: Exposure and clustering. There was a decline in evenness and concentration, and a variety of situations in terms of centralization. The evolution of the segregation indices indicates a diversity of segregation patterns: an increase of segregation according to exposure and clustering dimensions, a decline in evenness and concentration, and a variety of situations in terms of centralization. Finally, the findings confirm the presence of ethnic enclaves following seven years of growth in the immigrant population.
