We define a set of universal, irreducible and essential set of material conditions for achieving basic human wellbeing, along with indicators and quantitative thresholds, which can be operationalized for societies based on local customs and preferences. We draw support for this Decent Living Standard (DLS) from different accounts of basic justice, including the capability approach, basic needs, and primary goods. The DLS goes beyond existing multidimensional poverty indicators by comprehensively addressing living conditions and the means of social participation. The DLS offers a normative basis to develop minimum wage and reference budgets, and to assess environmental impacts, such as climate change, of eradicating poverty.
