The 130 members in the Chamber of Deputies ("Cámara de Diputados") (excluding the seven special seats) are elected using the additional member system. 63 seats are elected in single-member districts using first-past-the-post voting. 60 additional seats are elected using closed list party-list proportional representation in districts of varying sizes corresponding to Bolivia's nine departments. For parties receiving at least 3% of the national vote, the seats are distributed using the D'Hondt method, subtracting the number of seats the respective party gained from the single-member districts in the respective department. If one party has more seats from the single-member districts alone than the proportion of list vote it received, the extra seats are taken from the last allocated list seats.
