Pakistan Bureau of Statistics in the context of "List of most populous cities in Pakistan"

This is a list showing the most populous cities in Pakistan as of the 2023 Census of Pakistan. City populations found in this list only refer to the population found within the city's defined limits and any adjacent cantonment, if exists (except for Gujranwala and Okara). The census totals below come from the Pakistan Bureau of Statistics for the four provinces of Pakistan and the Islamabad Capital Territory, and from the Planning and Development Department of Azad Jammu Kashmir (PND AJK) for cities of Azad Kashmir.

As of the 2023 Pakistani census, there are two megacities, ten million-plus cities, in Pakistan. Overall 127 cities of the country, have a population of over 100,000. Of these 127 cities, 81 are located in the country's most populous province, Punjab, 22 in Sindh, 13 in Khyber Pakhtunkhwa, 8 in Balochistan, two in Azad Kashmir, and one is the Islamabad Capital Territory itself. It is unknown whether Gilgit-Baltistan has any city with over 100,000 people or not, as 2017 census results issued by the Government of Gilgit–Baltistan do not give figures for the population of cities in Gilgit–Baltistan. As in the previous census in 1998, the largest city of Gilgit-Baltistan was Gilgit, with 56,701 inhabitants.

The 2017 Census of Pakistan was a detailed enumeration of the Pakistani population which began on 15 March 2017 and ended on 25 May 2017. It was the first census taken in the country in the 21st century, nineteen years after the previous one in 1998, and it was carried out by the Pakistan Bureau of Statistics.

The census recorded a total population throughout the country of 213,222,917. The results showed a massive population increase having occurred between 1998 and 2017 of 77.0 million people, or an increase of +56.5%. The results also marked a significantly higher result compared to estimations made of the Pakistani population before the census, which had previously estimated the Pakistani population in 2017 to be between 195 million and 200 million.

The 2023 Census of Pakistan was the detailed enumeration of the Pakistani population and the seventh national census in the country. It was conducted by the Pakistan Bureau of Statistics. It was also the first ever digital census to be held in Pakistan, including the first in South Asian history.

The census was initially held from 1 March 2023 to 1 April 2023. However, enumeration was later extended several times until 30 May 2023, because of incomplete enumeration in large cities such as Karachi, Lahore, and Faisalabad, where people are more mobile and therefore harder to count, and in remote and rural Balochistan. The extension was also used by PBS officials and census takers for quality reviews, to check if all households and people were properly counted in each area. The 2023 census recorded a total population throughout the country of 241,499,431 (excluding Gilgit-Baltistan and Azad Kashmir).

The 1998 Census of Pakistan was the fifth Pakistani national census. It provided a detailed enumeration of the population of Pakistan at the time it was conducted under the authority of the Pakistan Bureau of Statistics, an agency of the Government of Pakistan. According to the 1998 census, the population of Pakistan proper (excluding disputed territories) stood at 130,857,717 people. With the inclusion of the population of Azad Jammu & Kashmir and Gilgit-Baltistan, the population stood at 134,714,017 people. Despite being mandated by the Constitution of Pakistan to be held every 10 years, this was the first census to take place in Pakistan after the 1981 census that took place 17 years earlier, and the next census would not be held for another 19 years, until 2017. The inconsistencies in Pakistan's national elections are due in part to political turmoil and instability within the country.

The Census in Pakistan is a legally decennial census and a descriptive count of Pakistan's population on Census Day, and of their dwellings, conducted and supervised by the Pakistan Bureau of Statistics. The most recent census was the 2023 Pakistani census.
