"Both within and across countries, most attention has been devoted to measuring inequality among individuals (and globally countries). Within countries, increasing evidence shows that inequalities among groups (HIs) are important for wellbeing. However, the global component of HIs are generally neglected. This paper argues that HIs at a global level may also be important for world stability and wellbeing, in much the same way HIs are relevant at the national level. With this perspective, the paper reviews Muslim/ non-Muslim HIs within developed and developing countries, and between Muslim and non-Muslim countries, finding that Muslims are systematically disadvantaged across many dimensions.
The paper also argues that, despite much heterogeneity among the Muslim population, there is evidence of
multiple global connections and of shared perceptions, such that inequalities faced by Muslims in one part of the world may become a source of grievance and potential mobilisation in other parts of the world. Consequently, socio-economic and political inequalities need to be addressed globally, within countries and between them, and politically as well as with respect to socio-economic and cultural status."
