"The population of undivided India in 1947 was approx 390 million. After partition, there were 330 million people in India, 30 million in West Pakistan, and 30 million people in East Pakistan (now Bangladesh)." Once the boundaries were established, about 14.5 million people crossed the borders to what they hoped was the relative safety of religious majority. The 1951 Census of Pakistan identified the number of displaced persons in Pakistan at 7,226,600, presumably all Muslims who had entered Pakistan from India; the 1951 Census of India counted 7,295,870 displaced persons, apparently all Hindus and Sikhs who had moved to India from Pakistan immediately after the partition. The overall total is therefore around 14.5 million, although since both censuses were held about 4 years after the partition, these numbers include net population increase following the mass migration.
