Despite growing interest in the relation between social justice and life satisfaction, there is a paucity of quantitative investigations linking these two constructs, even in the field of Community Psychology. To bridge this gap, we tested the relationship between the EU Social Justice Index (SJI; 2008-2017) and life satisfaction across 28 European Union (EU) countries, in a series of multilevel multinomial logistic regression models with cumulative logit link function. The SJI proved one of the strongest predictors of national life satisfaction, after controlling for time variation and other well-established country-level determinants. Our findings lend support to the hypothesis that social justice is highly related to life satisfaction. We invite scholars to explore this relationship further. We also recommend that EU governments strive to promote fairer social conditions to increase national happiness.
