The EU Social Progress Index (EU-SPI) is a measure of societal development and quality of life at the regional level that goes beyond the Gross Domestic Product. The Index measures social progress in European regions, at the NUTS2 level, using twelve components described by a total number of fifty-five comparable social and environmental indicators, purposefully excluding economic aspects. Its components are further aggregated into three broader dimensions describing respectively basic, intermediate and more sophisticated aspects of social progress.
