 While bureaucratic British officials completed reports on their zoological classification of Indian people, some British officials criticised these exercises as being little more than a caricature of the reality of caste system in India.The British colonial officials used the census-determined jatis to decide which group of people were qualified for which jobs in the colonial government, and people of which jatis were to be excluded as unreliable.These census caste classifications, states Gloria Raheja, a professor of Anthropology, were also used by the British officials over the late 19th century and early 20th century, to formulate land tax rates, as well as to frequently target some social groups as "criminal" castes and castes prone to "rebellion".
