Intergenerational mobility

Social mobility is the movement of individuals, families, households, or other categories of people within or between social strata in a society. It is a change in social status relative to others' social location within a given society.

Social mobility is defined as the movement of individuals, families, households, or other categories of people within or between layers or tiers in an open system of social stratification. Open stratification systems are those in which at least some value is given to achieved status characteristics in a society. The movement can be in a downward or upward direction. Absolute social mobility refers to the overall numbers of people who end up in a different layer of stratification from that of their parents. Relative social mobility refers to the differences in probability of attaining a certain outcome, regardless of overall structural changes; a society can have high absolute mobility and low relative mobility. The availability of at least some social mobility can be important in providing pathways to greater equality in societies with high social inequality.

Mobility is most often quantitatively measured in terms of change in economic mobility such as changes in income or wealth. Occupation is another measure used in researching mobility, which usually involves both quantitative and qualitative analysis of data, but other studies may concentrate on social class. Mobility may be intragenerational, within the same generation, or intergenerational, between one or more generations. Intragenerational mobility is less frequent, representing "rags to riches" cases in terms of upward mobility. Intergenerational upward mobility is more common, where children or grandchildren are in economic circumstances better than those of their parents or grandparents. In the US, this type of mobility is described as one of the fundamental features of the "American Dream" even though there is less such mobility than almost all other OECD countries.

Social mobility is highly dependent on the overall structure of social statuses and occupations in a given society. The extent of differing social positions and the manner in which they fit together or overlap provides the overall social structure of such positions. Add to this the differing dimensions of status, such as Max Weber's delineation of economic stature, prestige, and power and we see the potential for complexity in a given social stratification system. Such dimensions within a given society can be seen as independent variables that can explain differences in social mobility at different times and places in different stratification systems. In addition, the same variables that contribute as intervening variables to the valuation of income or wealth and that also affect social status, social class, and social inequality do affect social mobility. These include sex or gender, race or ethnicity, and age.
