Pakistan

Due to persecution of Muslims in India, even after the 1951 Census, many Muslim families from India continued migrating to Pakistan throughout the 1950s and the early 1960s. According to historian Omar Khalidi, the Indian Muslim migration to West Pakistan between December 1947 and December 1971 was from Uttar Pradesh, Delhi, Gujarat, Rajasthan, Maharashtra, Madhya Pradesh, Karnataka, Andhra Pradesh, Tamil Nadu, and Kerala. The next stage of migration was between 1973 and the 1990s, and the primary destination for these migrants was Karachi and other urban centres in Sindh.

In 1959, the International Labour Organization (ILO) published a report stating that from 1951 to 1956, a total of 650,000 Muslims from India relocated to West Pakistan. However, Visaria (1969) raised doubts about the authenticity of the claims about Indian Muslim migration to Pakistan, since the 1961 Census of Pakistan did not corroborate these figures. However, the 1961 Census of Pakistan did incorporate a statement suggesting that there had been a migration of 800,000 people from India to Pakistan throughout the previous decade. Of those who left for Pakistan, most never came back.

Indian Muslim migration to Pakistan declined drastically in the 1970s, a trend noticed by the Pakistani authorities. In June 1995, Pakistan's interior minister, Naseerullah Babar, informed the National Assembly that between the period of 1973–1994, as many as 800,000 visitors came from India on valid travel documents. Of these only 3,393 stayed. In a related trend, intermarriages between Indian and Pakistani Muslims have declined sharply. According to a November 1995 statement of Riaz Khokhar, the Pakistani High Commissioner in New Delhi, the number of cross-border marriages has dropped from 40,000 a year in the 1950s and 1960s to barely 300 annually.

In the aftermath of the Indo-Pakistani War of 1965, 3,500 Muslim families migrated from the Indian part of the Thar Desert to the Pakistani section of the Thar Desert. 400 families were settled in Nagar after the 1965 war and an additional 3000 settled in the Chachro taluka in Sindh province of West Pakistan. The government of Pakistan provided each family with 12 acres of land. According to government records, this land totalled 42,000 acres.

The 1951 census in Pakistan recorded 671,000 refugees in East Pakistan, the majority of which came from West Bengal. The rest were from Bihar. According to the ILO in the period 1951–1956, half a million Indian Muslims migrated to East Pakistan. By 1961 the numbers reached 850,000. In the aftermath of the riots in Ranchi and Jamshedpur, Biharis continued to migrate to East Pakistan well into the late sixties and added up to around a million. Crude estimates suggest that about 1.5 million Muslims migrated from West Bengal and Bihar to East Bengal in the two decades after partition.
