Demography
In August 1947, at the end of British Raj, the population percentage of Hindus in what is today Pakistan was perhaps 15% or higher, but would drop to its current total of 3.3% in the years since independence. According to the 1998 Pakistan Census, caste Hindus constitute about 1.6 percent of the total population of Pakistan and about 6.6% in province of Sindh. The Pakistan Census separates Schedule Castes from the main body of Hindus who make up a further 0.25% of national population. The total number of Hindus in Pakistan, including Scheduled Castes, however, is often suspected to be much higher than what was reported in the 1998 Census. According to unofficial reports, experts, and politicians, the real number of Dalits in Pakistan exceeds 2 million as opposed to 500,000 while the number of other caste Hindus is far higher than the 1.6% reported in the last census.
Based on the 1998 Census as well as the stabilization of Pakistan's Hindu population since then (and including the estimated 2 million Dalits that were left out of the last census), Pakistan would today have roughly 5.9 million Hindus. The Pakistan Hindu Council, however, puts this number at 5.5% of all Pakistanis, which would now be 9.9 million people in 2012.
