To arrange or classify into distinct categorical layers, social classes, or hierarchical strata.

Stratify emphasizes the division of a whole population or system into horizontal layers with differing levels of privilege, rank, or composition.

The story behind the word. Geologists in the 18th century first used 'stratify' to describe how sedimentary rock builds up in visible horizontal strata over millions of years. During the Industrial Revolution, sociologists borrowed the metaphor to explain how industrial societies separate into permanent socioeconomic classes.
