Why is caste identity in India both fluid and static?

Caste: both fluid and static

Caste in India is paradoxical — it persists as a rigid, ascriptive structure even as it continuously changes its form, functions and meaning.

Static dimensions

• Endogamy: marriage still overwhelmingly occurs within caste, plainly visible in matrimonial advertisements and family choices.
• Hierarchy and purity–pollution: ritual ranking and the practice of untouchability endure in many rural areas despite Article 17 abolishing it.
• Ascription: caste is assigned by birth and continues to shape life chances, social networks, discrimination and, at times, occupation.

Fluid dimensions

• Sanskritisation: M.N. Srinivas showed how lower castes emulate the customs and rituals of higher castes to claim upward status.
• Politicisation: caste has become a powerful resource for mobilisation — through caste associations, the Mandal moment and the assertion of OBCs and Dalits.
• Structural change: reservation, mass education, urbanisation and the market loosen ritual rigidity, and Louis Dumont described the “substantialisation” of caste into competing, ethnicity-like blocs.

Reconciliation

• The birth-based identity itself stays fixed, but its hierarchy, meaning and political use are constantly renegotiated in modern life.

Caste therefore transforms rather than dissolves — which is precisely why B.R. Ambedkar's call for the “annihilation of caste” remains unfinished business.
