2021 Chilean Constitutional Convention election

The Constitutional Convention is composed of 155 members, of which 138 are directly-elected by the electorate at large and 17 are reserved for indigenous peoples, directly-elected by themselves.

The 138 members are chosen in 28 constituencies of between three and eight seats by open list proportional representation. Seats are allocated using the D'Hondt method.[3] It is the same system used to elect member of the Chamber of Deputies, with the exception that a gender parity rule may make some adjustments to the election results necessary.[4]

The 17 seats reserved for Chile's Indigenous peoples are as follows: 7 for the Mapuche, 2 for the Aymara, and 1 each for the Diaguita, Quechua, Atacameño, Qulla, Chango, Rapa Nui, Kawésqar, and Yaghan peoples.[5]
