Even after partition in 1947, Indian Muslims continued to migrate to Pakistan throughout the 1950s and 1960s, and these migrants settled mainly in Karachi and other towns of Sindh province. The wars in neighboring Afghanistan during the 1980s and 1990s also forced millions of Afghan refugees into Pakistan. The Pakistan census excludes the 1.41 million registered refugees from Afghanistan, who are found mainly in the Khyber-Pakhtunkhwa and tribal belt, with small numbers residing in Karachi and Quetta. Pakistan is home to one of the world's largest refugee populations. In addition to Afghans, around 2 million Bangladeshis and half a million other undocumented people live in Pakistan. They are claimed to be from other areas such as Myanmar, Iran, Iraq, and Africa.
