Kamma or the Kammavaru is a social group found largely in the Southern Indian states of Andhra Pradesh, Tamil Nadu and Karnataka. According to 1921 census they constituted about 4.8% of Andhra Pradesh population and in significant numbers in Tamil Nadu and Karnataka.In the last decades of the previous century, a sizable number of kammas emigrated to other parts of the world, particularly to the United States, United Kingdom and Australia.kammas are the most influential community in Andhra Pradesh today is the Kamma, or Chowdhary community.
In a numerical ranking (by population size) kammas would probably be
fifth or sixth, but they are concentrated in some areas like Krishna,
Guntur, Southern parts of the Godavari river delta, Nizamabad in
Telangana and some places of Rayalseema like Anantapur. But the
influence they wield is all out of proportion to their numbers. There
are good reasons for this: as communities go, they are very wealthy,
besides they have a progressive social outlook and work VERY hard at
anything they take up. This includes education, culture and arts,
industry too, not just farming and they are justifiably proud of their
accomplishments. One very great and striking characteristic is their
readiness to undertake manual labour in agriculture, which is generally
considered something to be avoided in India for the upper castes.
