Independence, migration, and displacement

Mass migration occurred between the two newly formed states in the months immediately following the partition. There was no conception that population transfers would be necessary because of the partitioning. Religious minorities were expected to stay put in the states they found themselves residing. An exception was made for Punjab, where the transfer of populations was organized because of the communal violence affecting the province; this did not apply to other provinces.

The population of undivided India in 1947 was about 390 million. Following the partition, there were perhaps 330 million people in India, 30 million in West Pakistan, and 30 million people in East Pakistan (present-day 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.
