Intragenerational mobility follows change within one person’s life or career. Intergenerational mobility compares a person’s position with that of a parent or earlier generation. A promotion from technician to manager is intragenerational. Holding a higher occupational category than one’s parents is intergenerational. One case can be both upward and intergenerational because direction and time frame answer separate questions.

Structural mobility results when the distribution of positions changes. If an expanding health sector creates thousands of professional jobs, many people can move upward even while family origins still affect who reaches the most desirable positions. A contraction can create broad downward movement when an industry disappears.

Exchange mobility is movement within a relatively stable distribution. Some people rise as others move down, so the number of positions at each level changes little. Structural mobility changes the shape of the opportunity structure, while exchange mobility reshuffles people within it. Real mobility can contain both.

A mobility table places origins in rows and destinations in columns. The diagonal records people who remain in the same category. Off-diagonal cells record movement. Whether a cell represents upward or downward mobility depends on how categories are ordered, so a reader should inspect the labels before interpreting direction.

Read each row as 100 people who share an origin. Among children from lower-position families, 55 move away from that origin, including 15 who reach the higher category. Among children from higher-position families, 65 remain there. The table shows movement and a continuing association between origin and destination. It does not prove why the association exists.

Absolute mobility asks how many people occupy a different position from their parents. Relative mobility asks how strongly origins shape the chance of reaching a destination compared with people from other origins. A society can show high absolute upward mobility during occupational expansion while relative advantage remains strong.

Measurement depends on the chosen rank. Income, education, occupational prestige, workplace authority, and relational class location need not move together. A worker can gain pay while losing schedule control, or change occupation while keeping similar prestige. State the dimension before labeling a move.

Mobility evidence should also separate opportunity from outcome. If children from every origin can legally apply to a profession, formal access is open. If entry rates remain sharply unequal, researchers then examine schooling, wealth, networks, discrimination, location, and selection procedures. A table establishes the pattern. A causal claim needs evidence about the pathway.

Quick review: Vertical describes direction, while horizontal describes similar rank. Intragenerational follows one life, while intergenerational compares generations. Structural mobility changes the distribution of positions, while exchange mobility reshuffles people. A mobility table can show movement and origin effects without proving their cause.

Elena and Marcus began with the same paycheck and different security. The chapter’s central lesson is that no single number explains their position. Assets and debt, occupational rules, workplace control, institutional power, and family origins shape the opportunities attached to income. Those forces change probabilities rather than dictating a life. Chapter the related chapter next asks how race and ethnicity become socially meaningful group boundaries and how prejudice, discrimination, and institutions connect those boundaries to unequal life chances.
