Stratification is the process of classifying a set of data into categories or subgroups based on a set of predetermined criteria. This includes both ranked categories and unranked categories. For example wealth is a great example of social stratification, where it assigns each person to a hierarchical group based on their level of wealth. There is also unranked stratification, such as subcategorizing a population into gender groups.
