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.
2018 Pakistani Senate election
In terms of seats, there is fixed representation of each of the country's administrative unit in the senate, apart from the disputed territories of Gilgit-Baltistan and Azad Kashmir. There are 23 seats from each province, 8 from Federally Administered Tribal Areas, and 4 from the capital region of Islamabad. In a given election, half of these seats are contested for. Due to the odd nature of the number of seats from the provinces, each election cycle sees two provinces elect all 12 representatives, while the remaining two elect 11.
