All societies are stratified on a hierarchical basis into social categories—that is, into social strata. Individuals are born into a particular stratum. They become a member of the social category to which their parents belong. Individuals born into a stratum toward the top of the social hierarchy tend to have better life chances than those born into a stratum toward the bottom of the hierarchy. They are likely to have better education, health, standard of living, and work opportunities. (pg. 94)
