The map shows the share of affected religious minorities in the population of pre-Partition India according to the census of 1931, and in India and Pakistan three years after the Partition (in the 1951 censuses). The shares of Muslim populations in Indian Punjab fell to insignificant levels by 1951, as did the shares of Hindu and Sikh populations in West Pakistan. In contrast, in the east (UP, Bihar and Central and Southern India), the disappearance of minority population shares was much more muted.
