The decoupling of socioeconomic status, postmaterialism, and environmental concern in an unequal world: a cross-national intercohort analysis

There has been an intense yet inconclusive debate over the impacts of socioeconomic status (SES) and postmaterialism on environmental concern. Recent years have seen a growing interest in addressing the controversy by exploring the conditioning effect of social context. Previous studies of inequality argue that it unevenly exposes people to environmental degradation, reduces social cooperation, and erodes egalitarian values. This study integrates the two lines of research by linking social inequality to environmental sustainability and examines the extent to which inequality shapes the impact of SES and postmaterialism on environmental concern in the cross-national intercohort context. Analyses of multiple waves of the World Values Survey data using the hierarchical age-period-cohort modeling techniques suggest that contextual inequality substantially attenuates the effects of SES and postmaterialism. This relationship is consistent across countries with different economic development levels and more pronounced in older cohorts. The current study illustrates the importance of careful consideration of social conditions, the unequal distribution of income in particular, when examining predictors of environmental concern, and sheds light on the theorization of a more inclusive, balanced human-nature relationship.
