Pakistanis head to the polls Monday for parliamentary elections that will determine the make-up of the National Assembly -- or lower house of parliament -- and the country's four provincial assemblies.
The National Assembly consists of 342 members, including 272 general seats, 60 seats reserved for women, and 10 reserved for non-Muslims.
General seats are elected through direct-vote and the reserved seats are filled through a proportional representation system.
Pakistan is divided into the four provinces of Sindh (61 general seats), Punjab, Baluchistan (14 general seats), and North West Frontier Province (35 general seats). Punjab has the most seats in the assembly at 148.
There are 12 seats for Pakistan's federally administered tribal areas -- and just two for the capital, Islamabad.
The seats in each provincial assembly are also divided into general seats and those allotted for women and non-Muslims.
Pakistan is the seventh-most populous country in the world and has roughly 81-million registered voters.
