The Chamber of Deputies () is the lower chamber of the Plurinational Legislative Assembly, the bicameral legislature of Bolivia. Like the upper chamber, the Senate, it meets in La Paz, the seat of government. It is an elected body consisting of 130 members and their substitutes, known as deputies. Deputies Deputies serve five-year terms, and must be aged at least 25 on the day of the election.
Electoral system The Chamber of Deputies comprises 130 seats (including the seven special seats), elected using a seat linkage based mixed compensatory system using a two votes: 63 deputies are elected by first-preference plurality to represent single-member electoral districts, 60 are elected by closed list party-list proportional representation from party lists on a departmental basis (in districts of varying sizes corresponding to Bolivia's nine departments with a threshold of 3%). The list seats in each region are awarded proportionally based on the vote for the presidential candidates, subtracting the number of single-member districts won (to provide mixed-member proportional representation via additional member system). The remaining seven seats are reserved indigenous seats elected by the usos y costumbres. A voter can only vote in one of either the normal constituencies or special constituencies (coexistence).
The election uses the same votes as the votes for the President and the Senate, making it a double (triple) simultaneous vote. Voters may therefore not split their ticket between these elections, but they may vote for a candidate of a different list in the election of the Chamber as the deputies from the single-member districts are elected using separate votes.
Party lists are required to alternate between men and women, and in the single-member districts, men are required to run with a female alternate, and vice versa. At least 50% of the deputies from single-member districts are required to be women.
