Inequality Concepts serve as a meta-category for the abstract ideas, theoretical constructs, and analytical frameworks that sociologists use to understand, measure, and explain the existence of disparities and unequal distribution of valued resources, opportunities, and power within and across societies. This category groups fundamental concepts that help delineate the nature and dimensions of social stratification and its consequences. Examples include social inequality (the general condition of unequal access), wealth (total assets), income (earnings), prestige (social honor), and power (ability to exert influence). It also encompasses concepts like life chances (opportunities for well-being) and vested interests (groups benefiting from the status quo) that shed light on how inequalities are structured and maintained. These concepts provide the essential vocabulary for analysing how social categories (like class, race, gender, disability) lead to systematic advantages and disadvantages for different groups in society, and for theorizing about the causes, manifestations, and consequences of social stratification and social exclusion.
