The National Assembly is the lower chamber of Parliament in Burundi. It consists of 100 directly elected members (or deputies) and between 18 and 23 co-opted members who serve five-year terms. Deputies are elected in 17 multi-member constituencies using a party-list proportional representation system in accordance with the D'Hondt method. Political parties and lists of independent candidates must receive over 2% of the vote nationally to gain representation in the National Assembly.
