Administrative units of Pakistan
The administrative units of Pakistan () consist of four provinces (Balochistan, Khyber Pakhtunkhwa, Punjab, and Sindh), two autonomous territories (Azad Jammu and Kashmir, Gilgit-Baltistan) and one federal territory (Islamabad Capital Territory). Each province and territory is subdivided into divisions, which are further subdivided into districts, which are further subdivided into tehsils, or taluka, which are further subdivided into union councils.
West Pakistan
The western section of Pakistan dominated the politics of the new country. Although East Pakistan had over half of the population, it had a disproportionately small number of seats in the Constituent Assembly. This inequality of the two wings and the geographical distance between them was believed to be holding up the adoption of a new constitution. To diminish the differences between the two regions, the government decided to reorganise the country into two distinct provinces.
