Abstract: The Italian National Institute of Statistics (Istat) has set up a survey on income and living conditions (It-Silc), mainly composed of a cross-sectional and a longitudinal component.This paper aims at proving, by a decomposition of Gini concentration index, also known as Analysis of Gini (ANOGI), whether attrition introduces an element of bias in the analysis of income distribution. Compared to other studies in the literature, it introduces a new perspective by the direct evaluation of the attrition effect on studied variables.
