What is Social Mobility?
Social mobility is the movement of individuals, families or groups up or down the ladder of social stratification, resulting in a change of their relative status, income or occupation. It is the key measure of how "open" or "closed" a society is: where status is achieved through effort and merit, mobility is high; where status is ascribed at birth — as under the classical caste system — mobility is structurally restricted.
Types of Social Mobility
Sociologists classify mobility along two main axes:
| Basis | Type | Meaning |
|---|---|---|
| Direction | Vertical | Movement up or down between status levels (e.g. a labourer's child becoming an engineer) |
| Direction | Horizontal | Movement between positions of roughly equal rank (e.g. switching between two similar jobs) |
| Time frame | Intergenerational | Change in status across generations (parent to child) |
| Time frame | Intragenerational | Change within a single person's own lifetime |
| System | Open vs closed | Whether the wider stratification system permits movement at all |
Vertical, intergenerational mobility attracts the most research because it reveals whether inequality is tightening or loosening over time.
The Indian Context
The traditional caste system is the textbook example of a closed system — rank ascribed by birth, with status historically immutable. M.N. Srinivas captured the limited mobility available within it through Sanskritisation: the process by which a lower caste or tribal group adopts the rituals, diet and customs of a higher, "twice-born" caste to claim higher status. He paired this with Westernisation, the changes flowing from British rule across technology, institutions and values. Modern drivers of mobility include education, urbanisation, occupational diversification and constitutional affirmative action (reservation for SCs, STs and OBCs).
Current Status and Data
India's structural mobility remains comparatively low. On the World Economic Forum's first Global Social Mobility Index (2020), India ranked 76th of 82 economies with a score of 42.7, behind fellow BRICS members Russia (39th), China (45th) and Brazil (60th), and just ahead of South Africa (77th). India's weakest pillars were fair wage distribution and social protection. Recent academic work (Frontiers in Sociology, 2024; American Economic Association, 2024) finds intergenerational mobility has been broadly flat and low since before liberalisation, though affirmative action has measurably improved mobility for Scheduled Castes, while gains for Muslims have lagged and women's mobility trails that of men.
UPSC Angle
Treat social mobility as an analytical tool rather than a stand-alone fact. Use it to argue whether economic growth has genuinely dissolved ascriptive hierarchies or merely reshaped them, and to evaluate reservation, education and urbanisation as engines of vertical movement. Pair it with allied concepts — Sanskritisation, dominant caste, secularisation and the open/closed distinction — to add sociological depth to GS1 society answers. It is a foundation concept underpinning questions on caste, class and social empowerment, with current-affairs entry points such as the WEF index.
