The aim of this study was to investigate the perception of social injustice among adults in Croatia. Research problems were related to the level of social injustice perception, possible determinants of injustice, as well as the relationship between social injustice and quality of life. The study was conducted with 375 general population participants, heterogeneous in terms of different sociodemographic characteristics. In addition to these characteristics, responses were collected on the perception of social injustice and subjective quality of life. The results showed a high level of perceived social injustice in Croatia on all measured injustice subscales. The subscale with the highest overall level of perceived injustice was non-enforcement of the law by the state. The relationship between sociodemographic characteristics and social injustice factors indicate significant correlations between gender, age, education level and aspects of injustice, whereby the most pronounced relationship was with material status. As the material status got higher, perception on different forms of injustice was lower. In the regression analysis for quality of life criteria, 32.8% of the variance was explained. Sociodemographic characteristics explained 21.7%, with material status and education level being significant predictors. Social injustice factors had a significant incremental predictability for quality of life in addition to sociodemographic characteristics and explained an additional 11.1% of the criterion variance. In this step, personal experience of injustice and general injustice in society stood out as significant predictors.
