"No country in the world has been host to so many refugees as a 'shrinking and shrunken' India has been since the Partition in 1947... According to the estimate of the Government of India, 7.30 million people entered India between 1947-51 from the two wings of Pakistan. Except a few thousand Hindu families in Sindh, almost the entire Hindu and Sikh population were forced to leave their homes... In East Pakistan, the process was slow and systematic. Between 1947-51, the total number of people moving into India was estimated at 2.55 million... While West Pakistan was cleansed of its Kafirs except for a microscopic minority - being reduced from 23% in 1947 to 3% at present, the non-Muslim communities of East Pakistan/Bangladesh were reduced from 29% to 12% of the population. It is estimated that another 2.5 million Hindus fled the eastern wing of Pakistan during 1951-61... One finds that 90% of the total who fled East Pakistan in course of the liberation war of Bangladesh were Hindus... The extent of the missing Hindu population is estimated around 1.22 million during the last inter-censal period of 1981-91..."
