Horizontal mobility refers to the movement of an individual from one social position to another of the same rank or social status within the social hierarchy. This type of mobility involves a change in occupation, job, or social role that does not result in a significant upward or downward shift in terms of prestige, power, or income. For example, a teacher moving from one school to another, or a nurse changing hospitals, would be considered horizontal mobility, as their occupational status and social standing remain relatively the same. Horizontal mobility is a common occurrence in modern societies and reflects changes in individuals' careers or life circumstances without necessarily altering their position within the broader social stratification system.
