Social stratification refers to the classification of people into hierarchical groups based on criteria like wealth, income, education that are important to a society. It is a universal trait that is passed down generations and involves both inequality and beliefs about social status. Social stratification divides society into an upper class, middle class, and lower class. Under slavery in the Caribbean, stratification was based strictly on race and color, with white Europeans at the top, mixed or light-skinned people in the middle, and black slaves at the bottom. This racial hierarchy continued even after the abolition of slavery.
