Sindh was relatively spared from the violence despite the fact it had a large Hindu minority, while Balochistan, NWFP (now KP), the Tribal Areas and Northern Areas (now Gilgit-Baltistan) were all significant Muslim majority regions (>95%) and hence saw little to no violence. Jammu & Kashmir was excluded from this study.
One could argue had Punjab not been partitioned and remained with Pakistan, we would have seen a similar migration pattern as that witnessed in Sindh. In fact, migration from Sindh only increased after violence erupted in Punjab, otherwise a majority of the local Hindu population had no intent on leaving.
In the subsequent years, the population of Hindus in Pakistan has steadily increased, contrary to sensationalist propaganda from our eastern neighbour. Ironically after the secession of East Pakistan and the creation of Bangladesh, its Hindu population has decreased each year.
Furthermore, according to the Pew Research Center in 2010, Pakistan had the 5th largest Hindu population in the world at 3.33 million. By 2050, this will rise to the 4th largest in the world to 5.63 million.
