Partition of India
Once the lines had been established, about 14.5 million people crossed the borders to what they hoped was the safety of their religious majority. The 1951 Pakistani Census showed the number of displaced there at 7,226,600. They were presumably Muslims who had entered Pakistan from India. Similarly, the 1951 Indian Census showed 7,295,870 displaced people, apparently Hindus and Sikhs who had moved to India from Pakistan. Both numbers add up to 14.5 million. Other people came from China to take advantage of the open border.
