Social mobility refers to the movement of individuals or groups within the social hierarchy, changing social status and social class. It can involve moving up or down the social ladder, or remaining in the same position but within a different occupation. Social mobility is a social movement by a person or group from one social stratum or class to another, usually with the aim of improving their quality of life. This movement places the individual into a different social class as defined by the social stratification system. Social stratification results from structured human relationships within a society, where one's position determines their relationships with others, both vertically and horizontally.

Social Mobility
Mobility in the Big Indonesian Dictionary is defined as a moving movement or
readiness to move. Meanwhile, etymologically mobility comes from the Latin word 'mobilis'
which means easy to move or moves a lot from one place to another; the presence of the
word social in the term social mobility is to emphasize that the term implies involving a
person or group of citizens in a social group.
Ransford in Sunarto (2004:87) states, in sociology social mobility means a transfer
of status in social stratification; "Social mobility refers to the movement of individuals or
groups--up or down--within a social hierarchy". Komblum (1988: 172) states that social
mobility is the movement of individuals, families or social groups from one social layer to
another. In moving, it can affect the social status that is owned, that is, it can go up or down,
or even remain at the same level but in a different job.
In line with that, Paul B. Horton and Chester L. Hunt (in Bagong Suyatno, 2004: 202)
stated that social mobility is a movement of movement from one social class to another
social class or movement from one stratum to another, whether in the form of increase or
decrease in terms of social status and (usually) including income, which can be experienced
by several individuals or by all members of the group. Based on the explanation above,
simply social mobility can be interpreted as a movement/social movement carried out by a
person or group of people from one stratum (social class) to another, usually with the aim
of improving the quality of life.
Mobility carried out by someone will place that person in a social class (social
stratification) that is different from before. In social stratification there is a categorization of
classes called the class system that places them in a class according to the conditions they
have. According to Gitter in Susanto (1992: 65) social stratification is the result of the habit
of regular and structured human relations in which every person at any time has a situation
that determines his relationship with other people both vertically and horizontally in his
society. Stratification occurs from the wider community which is marked by the division of
labor.
