The U.S. government estimates the total population at 207.9 million (July 2018 estimate).  According to the provisional results of a national census conducted in 2017, 96 percent of the population is Muslim.  According to government figures, the remaining 4 percent includes Ahmadi Muslims (whom Pakistani law does not recognize as Muslim), Hindus, Christians, Parsis/Zoroastrians, Baha’is, Sikhs, Buddhists, Kalash, Kihals, and Jains.  Most of the historic Jewish community has emigrated.

Sources vary on the precise breakdown of the Muslim population between Sunni and Shia Muslims.  Sunnis are generally believed to be 80-85 percent of the Muslim population and Shia are generally believed to make up 15-20 percent.  Unofficial estimates vary widely with regard to the size of minority religious groups.  According to 2014 media accounts, although there are 2.9 million non-Muslims registered with the National Database and Registration Authority (NADRA), the actual number exceeds 3.5 million.  Religious community representatives estimate minority religious groups constitute 3 to 5 percent of the population.

According to the 2014 government registration documents cited by the press, there are approximately 1.4 million Hindus, 1.3 million Christians, 126,000 Ahmadis, 34,000 Baha’is, 6,000 Sikhs, and 4,000 Parsis.  Taking account of the Ahmadi boycott of the official census, however, community sources put the number of Ahmadi Muslims at approximately 500,000-600,000.  Estimates of the Zikri Muslim community, located in Balochistan, range between 500,000 and 800,000 individuals.  Several minority rights advocacy groups dispute the provisional results of the 2017 census and state the numbers underrepresent their true population.
