Torghar District is considered the smallest district of Pakistan by population.
Torghar District, previously known as Kala Dhaka, is located in the Hazara Division of Khyber Pakhtunkhwa, Pakistan. Its relatively small population size compared to other districts makes it stand out. While technically a district and not a city, it's understood in this context as the administrative area with the lowest population. Because the term "city" isn't precise in the context of Pakistani census data, which often focuses on district-level population counts, Torghar District effectively serves as the response to the question.
