Bijani House of Representatives election, 2005

The Bjiani House of Representatives election of 2005 took place on Sunday, March 6, 2005, to elect the 245 members of the 15th Bijani House of Representatives. The incumbent coalition government, consisting of the Liberal Democratic Party and One Nation, sought a third term in office against and opposition consisting of the Social Democratic Party and Together for Bijan.

Background
At the time of the 2005 election, the Liberal National Party had governed Bijan either alone or in coalition with One Nation for twelve years.

Electoral system
The Bijani House of Representatives is elected using open party-list proportional representation, whereby electors vote for individual candidates in multi-member constituencies. The total number of votes for all candidates of a particular party in each constituency are totalled, and the seats are apportioned out to the parties using the Sainte-Laguë method. The number of members each county elects is determined by the ratio of its population to the population of the whole country.

Since 1997, the House has had 245 seats, 199 of which are filled using the procedure outlined above. The remaining 46 seats are allocated, two per county, to parties which have received at least four percent of the nationwide vote. This measure is to ensure that the overall composition of parties in the house is proportional to the number of votes each party received.

Constituencies
Every eight years, the number of seats each constituency is allocated must be recalculated, to account for changing demographics in the country. The following changes were made to the 1997 distribution:
 * Hadar City and County: went from 16 seats to 17.
 * Olvek County went from 12 seats to 13.
 * Stolen Tree County went from 12 seats to 13.
 * Southport County went from 12 seats to 13.
 * Crownland County went from 11 seats to 12.
 * Copper County went from 8 seats to 7.
 * High Tide County went from 6 seats to 5.
 * Estuary County went from 6 seats 5.
 * River Valley County went from 4 seats to 3.
 * Sunrise County went from 4 seats to 3.
