Un nuevo enfoque para medir la desigualdad espacial de la renta en el Área Metropolitana de Barcelona

Abstract

This article puts forward a new approach for the estimation of the spatial distribution of earnings in the BMA. Instead of estimate data for small spatial units leaving from aggregated data and using inferential techniques, we create a new database which provides a different estimation for the spatial distribution of wage income in Barcelona Metropolitan Area (BMA). The database is obtained by matching data from the Wage Structure Survey (WSS) with data from the Census disaggregated by census tracts. It contains data on wage incomes for every census track for 36 municipalities belonging to the BMA in two periods (1995-2002). We use the family of Generalised Entropy Indices to measure the inequality and its variation. Further, we decompose the inequality into inter and intra-municipality measures.
