Vertical Stratification

Vertical stratification refers to the hierarchical ranking of individuals and groups in a society according to unequal access to wealth, power, prestige, and other valued resources. It is distinguished from horizontal differentiation, which describes differences between groups, such as occupation or ethnicity, that are not inherently ranked. Karl Marx analyzed vertical stratification in terms of class relations rooted in ownership of the means of production, while Max Weber broadened the picture by identifying class, status, and party as separate but interacting dimensions of inequality. Pitirim Sorokin, who helped popularize the distinction between vertical and horizontal social mobility, examined how people move up or down social hierarchies. Kingsley Davis and Wilbert Moore offered a functionalist account in which unequal rewards motivate people to fill important positions, a view criticized by Melvin Tumin. Pierre Bourdieu showed how economic, cultural, and social capital reproduce advantage across generations. Systems of vertical stratification include slavery, caste, estates, and class, each differing in how open it is to mobility. The concept remains central to research on inequality, social mobility, poverty, and the persistence of privilege in modern societies.
