The second objective is to quantify this index for a number of developing countries so that a government with low value of social justice index can make policy for achieving an appropriate level of social justice. Design/methodology/approach � The paper constructs a new composite index for social justice for 40 mostly developing countries by selecting six subindicators, each of which represents one aspect or dimension of social justice. The values of the subindicators are then normalized and the final composite index is formed from the weighted average of the subindicators. Findings � The study quantified the levels of social justice in developing countries through a new social justice index and compared the ranking of some developing countries using the new index. The index also helped in identifying areas of social justice that need improvement and hence can improve the developing countries' scores in the social justice index. Originality/value � The paper is valuable to policy makers in developing countries especially the Arab Spring countries in their pursuit for achieving social justice. Quantifying social justice clarifies exactly where such countries stand and the dimensions of social justice that need urgent action to improve their performance and thus their index scores. 2013, Emerald Group Publishing Limited.EnglishComposite indexDeveloping countriesDevelopmentIndicatorsSen's capabilitiesSocial justiceArticlehttps://doi.org/10.1108/14468951311322127PubMed ID :
