Un archivio longitudinale amministrativo per la stima della povertà a livello locale

In this study, a longitudinal income database based on administrative data was set up aiming at estimating income and poverty of households and individuals living in the municipality of Brescia in the period 2005-2008. This was achieved by linking data sourced from the Population Register and fiscal authorities. The definition of poverty was obtained through a one - dimensional approach, based on a single indicator (“declared” income) and a local relative poverty line, evaluated with reference to the municipality of Brescia. The paper includes a description of both the used methodology, highlighting the problems faced and the adopted solutions, and of the main estimates of poverty rates from a crosssectional and longitudinal perspective.
