Social Mobility

The promise: talent and effort decide your fate. The reality is more complicated.

  • Define social mobility
  • Explain absolute vs relative mobility
  • Evaluate education’s role

Social Mobility

Every society claims the talented can rise. Sociologists ask: how often does it actually happen — and for whom?

Definition: Social mobility

Social mobility is movement between social classes — upward or downward, within a lifetime (intragenerational) or between generations (intergenerational). Absolute mobility = the whole structure shifting; relative mobility = changing position within it.

Key points

  • Absolute mobility rose with industrialisation — more middle-class jobs for everyone’s children.
  • Relative mobility (your chances vs someone else’s) has barely budged in many countries.
  • Education helps individuals but credentials inflate: degrees are worth less as more people hold them.
  • The ‘glass floor’: affluent children rarely fall far, whatever their grades.
The Great Gatsby curve

Countries with higher inequality have lower mobility — the rungs are further apart and harder to climb. Scandinavia is mobile; the US and UK less so than they believe.

Practice

Distinguish absolute and relative mobility.
Bigger pie vs bigger slice.

Absolute: more people moving up because the class structure itself expanded. Relative: individuals changing rank within an unchanged structure.

Why hasn’t expanding education equalised mobility?
Credentials inflate; advantages persist.

Degrees devalue as they spread, and affluent families buy advantages (tutoring, networks, unpaid internships) that qualifications alone can’t offset.

Key takeaways
  • Mobility = movement between classes, up or down.
  • Absolute mobility grew; relative mobility is sticky.
  • Education aids individuals but hasn’t equalised chances.
  • Inequality and mobility are linked (the Gatsby curve).
