Electoral system
Since 2017, Chile's congress has been elected through open list proportional representation under the D'Hondt method.

Before 2017, a unique binomial system was used. These system rewards coalition slates. Each coalition could run two candidates for each electoral district's two Chamber seats. Typically, the two largest coalitions in a district divided the seats, one each, among themselves. Only if the leading coalition ticket out-polls the second-place coalition by a margin of more than two-to-one did the winning coalition gain both seats. with seats allocated using the simple quotient. The Chamber of Deputies meets in Chile's National Congress located in the port city of Valparaíso, some 120 km west of the capital, Santiago. The Congress building in Valparaíso replaced the old National Congress, located in downtown Santiago, in 1990
