Answer:
Social mobility is the set of movements or displacements made by individuals, families or social groups within a given socioeconomic system. Sociology studied this phenomenon within the framework of social class theories, social stratification, meritocracy and social status. The etymological origin of the word mobility is Latin and activated of the word mobility (mobile) and the suffix -tad, the latter used to define an abstract quality. The specified social word of Latin "social" and relates to belonging to a phenomenal community.
Ideally, societies should have greater social mobility. This means that people who strive and have merit (hence the association with the concept of meritocracy) and through this process improve their quality of life and climb the social ladder. In contrast, a society with low mobility generates social genres with little hope of progress for its members, so people have restrictions to maintain the social status of their ancestors regardless of their personal effort.
