M. Pratesi: La misura della povertà educativa
Giusti, C., Masserini, L., & Pratesi, M. (2017). Local Comparisons of Small Area Estimates of Poverty: An Application Within the Tuscany Region in Italy. Social Indicators Research, 131(1), 235-254.
The aim of this paper is to highlight some key issues and challenges in the analysis of poverty at the local level using survey data. In the last years there was a worldwide increase in the demand for poverty and living conditions estimates at the local level, since these quantities can help in planning local policies aimed at decreasing poverty and social exclusion. In many countries various sample surveys on income and living conditions are currently conducted, but their sample size is not enough to obtain reliable estimates at local level. When this happens, small area estimation (SAE) methods can be used. In this paper, a SAE model is used to compute the mean household equivalised income and the head count ratio for the 57 Labor Local Systems of the Tuscany region in Italy for the year 2011. The caveats of the analysis of poverty at the local level using small area methods are many, and some are still not so well explored in the literature, starting from the definition of the target indicators to the relevant dimensions of their measurement. We suggest in this paper that together with the universally recognized multidimensional, longitudinal and local dimensions of poverty, a new dimension must be considered: the price dimension, which should take into account local purchasing power parities to correctly compare the poverty indicators based on income measures.

The importance of poverty measures (indicators and number of poor) at sub-national level is widely attested. Particularly, the local poverty indicators are relevant both for a detailed planning of the policy actions against poverty and social exclusion and for the citizens to evaluate their effect. However, there are still open problems to compute adequate sub national poverty indicators. They refer to: 1) the definition of poverty lines; 2) the methods for accounting the spatial variation of cost of living to make comparisons in real terms between different areas; 3) the use of Small Area Estimation methods when sample size is not enough to obtain accurate estimates of the indicators at local level. In this paper, we discuss all these problems in a coherent way, presenting analyses on the impact of the different choices on the value of poverty rates for the 20 Italian Regions and computing the estimations of the poverty rates at the sub-regional level by using SAE methods. The key results underlined the strong differences in the territorial distribution of poor by using national specific versus sub-national specific poverty lines, while the effect of the heterogeneity of the spatial price indexes seems less important.
