Starting with the 1901 Census of India led by colonial administrator Herbert Hope Risley, all the jātis were grouped under the theoretical varnas categories. According to political scientist Lloyd Rudolph, Risley believed that varna, however ancient, could be applied to all the modern castes found in India, and "[he] meant to identify and place several hundred million Indians within it." The terms varna (conceptual classification based on occupation) and jāti (groups) are two distinct concepts: while varna is a theoretical four-part division, jāti (community) refers to the thousands of actual endogamous social groups prevalent across the subcontinent. The classical authors scarcely speak of anything other than the varnas, as it provided a convenient shorthand; but a problem arises when colonial Indologists sometimes confuse the two.
