Abstract
Over the last years, a growing interest about the study of older people deprivation across countries has emerged in the literature. Usually, to evaluate it, composite indicators aiming at capturing different aspects have been defined to analyse such phenomenon. However, different indices produce different country rankings and it is not always feasible to combine them. Consequently, it is not possible to unambiguously define an order among the countries that takes into account the different aspects. To overcome this problem, here, we propose an iterative procedure, the so-called Voronoi algorithm. Thus, we define deprivation by means of two composite indicators, the first one capturing the physical-economic aspect of deprivation and the second the social one. The Voronoi algorithm combines the two dimensions of deprivation into one, generating a single, unified country ranking. Data come from the Survey of Health, Ageing, and Retirement in Europe (SHARE) and refer to the COVID-19 period, that is 2019-2020 and refer to European Countries, grouped into Mediterranean countries, Continental countries and Nordic countries.
