Introduction
Caste is defined as closed and ascriptive, yet ranks in any locality have always moved. Mobility in the caste order is a group claim to a higher position, made over generations and conceded, or refused, by neighbours.

Body
1. What mobility can mean here: Dumont's model of fixed ritual rank leaves no room for it, but Srinivas showed that the middle of the local hierarchy is ambiguous and contested. The unit that moves is therefore the caste or sub-caste, not the individual, and the movement is a claim rather than an appointment.
2. The types: Sanskritisation, which Srinivas drew from the Coorgs — adopting vegetarianism, teetotalism, the sacred thread and a new caste name, as the Nadars of Tamil Nadu and the Yadavs and Kurmis of the north did through Kshatriya genealogies. Westernisation offers the alternative route through English education and office. Srinivas distinguished positional change, in which one group replaces another without the ladder itself altering, from structural change, in which the ladder changes. Mobility can also be downward, and Ambedkar's mass conversion to Buddhism in 1956 was exit rather than ascent.
3. The factors: land reform, tenancy legislation and the green revolution created surpluses — Bailey's Bisipara distillers bought land and claimed warrior status; reservation and education under Articles 15(4) and 16(4); electoral numbers, caste associations and the Mandal implementation of 1990; migration to towns, where origin is unknown; and census enumeration, which since 1901 has been the arena for claims, and which returns in the Census now scheduled for 2027.
4. The limits: Srinivas himself noted that Sanskritisation does not work for those treated as untouchable, whose claims meet violence rather than concession, and that it raises rank without disturbing the principle of rank itself.

Conclusion
Caste mobility is real, collective and slow, and it is secular power that makes the ritual claim credible. What has changed since Srinivas wrote is that groups now claim backwardness rather than high status, because the state, not the neighbour, is the audience.
