Our world is undergoing major population changes that are simultaneously shaping and being shaped by geographical and social inequalities. Global population growth continues, albeit more slowly, while many economies face population aging and declining birth rates. Migration flows, both intranational and international, have surged. Urbanization is rising globally. We seek papers that analyze the dynamic interrelationships between these population changes and inequalities in different spheres, including (but not limited to) economic, political, educational, health, gender, sexuality, and ethnicity etc. In addition, we welcome submissions regarding other topics in Sociology.
