Electoral divisions of Chile

To elect members of the Chamber of Deputies and of the Senate, Chile is divided into several electoral divisions, namely electoral districts and senatorial constituencies.

Electoral districts

Notes: "VAP" is voting age population (population 18 and above on 13 December 2009); "Valid votes" is equal to "Total votes" minus spoilt votes (blank and null votes); "T" are total votes; "E" is enrolled population; "V" are valid votes. The voting results are for the 13 December 2009 Chamber of Deputies election.

Senatorial constituencies

There are 19 senatorial constituencies (circunscripción senatorial). Each Chilean region constitutes a senatorial constituency, except regions V, RM, VII, VIII and IX, which are each divided into two senatorial constituencies. Each senatorial constituency elects two Senators. Senatorial constituencies which are not full regions are made up of several electoral districts within a region.

In 2009 the Constitution was modified so that each region constitutes at least one senatorial constituency. The law determining senatorial constituencies has not been revised to reflect this change, so the list continues to be as follows:

Arica and Parinacota Region (XV), Tarapacá Region (I) Antofagasta Region (II) Atacama Region (III) Coquimbo Region (IV) Valparaíso-Cordillera: Districts 10, 11 and 12 of Valparaíso Region (V) Valparaíso-Coast: Districts 13, 14 and 15 of Valparaíso Region (V) Santiago-West: Districts 16, 17, 18, 19, 20, 22, 30 and 31 of Santiago Metropolitan Region (RM) Santiago-East: Districts 21, 23, 24, 25, 26, 27, 28 and 29 of Santiago Metropolitan Region (RM) O'Higgins Region (VI) Maule-North: Districts 36, 37 and 38 of Maule Region (VII)

Maule-South: Districts 39 and 40 of Maule Region (VII) Biobío-Cordillera: Districts 42, 43, 44 and 45 of Biobío Region (VIII) Biobío-Coast: Districts 41, 46 and 47 of Biobío Region (VIII) Araucanía-North: Districts 48 and 49 of Araucanía Region (IX) Araucanía-South: Districts 50, 51 and 52 of Araucanía Region (IX) Los Ríos Region (XIV) [Before August 15, 2009: Los Ríos Region (XIV) and district 55 of Los Lagos Region (X)][2] Los Lagos Region (X) [Before August 15, 2009: Districts 56, 57 and 58 of Los Lagos Region (X)][2] Aisén Region (XI) Magallanes Region (XII)
