Electoral divisions of Chile

Chile has two distinct electoral division systems:

• 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.
• To elect members of the Regional Councils, Chile is divided into several provincial constituencies, each of which correspond to one province, except for a few ones that are divided into several constituencies.

Electoral districts

There are 60 electoral districts (distrito electoral). Each district elects two deputies. Districts are made of groups of communes.

Senatorial constituencies

There are 19 senatorial constituencies (circunscripción senatorial). Each 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:
