The Sikhs now constituted a majority in the northwestern seven districts of the thirteen districts of East Punjab state at the time: Gurdaspur, Amritsar, Hoshiarpur, Jalandhar, Firozpur, Ludhiana, and Ambala, along with Patiala and East Punjab States Union, or PEPSU, which had been formed as an administrative unit in May 1948 out of the six Sikh princely states, and with sizable populations in surrounding districts. Meanwhile, Hindus formed a majority in the remaining six, including the southeastern districts between PEPSU and Delhi (Hisar, Karnal, Rohtak, and Gurgaon), and the eastern Kangra and Shimla divisions. In addition, while the Sikhs made up 35% of the province's population, the demographic pattern of urban and rural settlement was such that the Hindu population, whose majority status was new, was largely clustered in urban areas. The seven Sikh-majority districts would be the suggested basis of the Punjabi Suba, for which Tara Singh campaigned vigorously between late 1948 and early 1949.
