The house is elected by
party-list proportional representation with open lists. For the first two elections, representatives were elected from nationwide lists, but in 2000, local representation was introduced. Eight constituencies, known as
electoral units, each elect between three and six representatives, giving a total of 30. To ensure proportionality, a further 12 representatives are elected on an entity-wide basis. Each entity is allocated a number of these entity-wide seats, 7 members from the
Federation of Bosnia and Herzegovina and 5 from
Republika Srpska. When a party is entitled to one of these entity-wide seats, it is given to the candidate from the party who receives the most votes without being elected in his or her electoral unit, located in one of the two entities.
Brčko District voters are entitled to vote in only one of the two entities. Their vote is allocated to the corresponding electoral unit, depending on which entity the voter is voting from. ==Current composition==
