Intergenerational mobility is the movement in social position between different generations of the same family, most commonly measured by comparing an adult persons social position with that of their parents. It is used to examine the extent to which family origins are associated with social destinations. Researchers may compare occupations, social classes, income positions, educational attainment or other socioeconomic characteristics between parents and children.
For example, if a person enters a substantially different occupational class from that occupied by their parents, the difference may represent intergenerational occupational mobility. The concept is central to research on equality of opportunity because it asks whether social position is strongly transmitted across generations or whether people commonly reach destinations different from those associated with their family origins. Intergenerational mobility can be upward, downward or horizontal, depending on the direction and magnitude of the change.
Intergenerational mobility should be distinguished from intragenerational mobility. Intergenerational analysis compares one generation with another, while intragenerational analysis examines movement within the lifetime of one individual. A person can therefore have high intergenerational mobility but little intragenerational mobility if they enter a different occupational class from their parents and remain there throughout their career.
Conversely, a person may have low intergenerational mobility but substantial intragenerational mobility if they begin and end their career in the same broad class as their parents while moving through several positions during adulthood. The distinction allows researchers to separate family transmission from career development and to examine how childhood circumstances and adult opportunities operate over different periods.
Intergenerational mobility is often measured using occupational class schemes because occupation provides a relatively stable indicator of socioeconomic position and can be compared between parents and adult children. Researchers may construct origin and destination categories and examine how frequently people remain in the same category or move into another. Income based research may compare parental income with adult child income, often using relative income rank rather than raw income because economic distributions change over time. Educational mobility can compare the highest qualifications of parents and children. Each method captures a different aspect of intergenerational mobility. Consequently, findings from occupational, educational, income and wealth studies should not automatically be treated as interchangeable evidence about the same dimension of mobility.
Family resources are among the mechanisms that can influence intergenerational mobility. Parents can transmit economic resources through housing, savings, inheritance, educational expenditure and financial assistance. They can also transmit cultural resources through language, educational expectations, knowledge of institutions and familiarity with professional environments. Social networks may provide information, introductions and opportunities that affect educational or occupational destinations. These mechanisms can contribute to the persistence of social advantage across generations. However, family transmission does not imply deterministic outcomes. Education systems, labour markets, public policy, geographic mobility, individual decisions and wider structural changes can alter the relationship between origin and destination. Intergenerational mobility therefore measures patterns of association rather than proving that parents directly determine the outcomes of their children.
Structural change is crucial when interpreting intergenerational mobility. If an economy changes from manufacturing toward professional and service employment, many children may enter occupations that their parents could not have entered simply because the occupational structure itself has changed. This can produce substantial absolute mobility. Researchers therefore distinguish structural mobility from exchange mobility. Structural mobility arises because the number or distribution of available positions changes, while exchange or relative mobility concerns movement between positions within a given distribution. A society can have high absolute mobility because its occupational structure expands in new directions while still having unequal relative chances between people from different family origins. This distinction is fundamental to interpreting intergenerational mobility statistics.
Intergenerational mobility is closely connected to social reproduction, the process through which social advantages and disadvantages persist across generations. High rates of intergenerational persistence indicate that family origins remain strongly associated with destinations, whereas greater mobility indicates weaker correspondence between origins and destinations. However, mobility and inequality are not identical. A society can have substantial mobility while retaining large differences in income and wealth, because individuals may move between unequal positions without changing the overall distribution of resources. Similarly, high educational mobility may coexist with persistent wealth inequality if inherited property remains concentrated. Researchers therefore examine both mobility rates and the underlying distribution of resources rather than assuming that one measure completely describes social equality.
Gender, ethnicity, geography, migration and historical period can affect intergenerational mobility patterns. Different groups may encounter different educational opportunities, labour market structures, discrimination, housing markets or family resources. Regional labour markets can also influence destinations because professional and high wage occupations are concentrated differently across places. Historical comparisons require particular caution because the meaning and availability of occupations, qualifications and income levels change over time. Researchers must therefore consider cohort effects and changes in classification systems when comparing generations. A difference between parents and children can represent genuine mobility, but it can also partly reflect changes in the economy or measurement system.
Intergenerational mobility is important for understanding whether social origin continues to shape life chances. It is used in sociology, economics, education research and public policy to investigate inequality of opportunity, educational attainment, occupational inheritance, income persistence and wealth transmission. Contemporary research increasingly considers wealth as well as income because inherited property and financial assets can strongly influence housing, education and economic security. Longitudinal data allow researchers to follow families across generations and examine how advantages accumulate. Intergenerational mobility is therefore best understood as a comparative measure of movement between family generations, requiring clearly defined origin and destination indicators and careful separation of individual movement from structural economic change.
