2021 Chilean Constitutional Convention election

Ballots used for the Constitutional Convention election: beige ballot for at-large election in the 10th district (left) and green ballot for Mapuche reserved seats. (right).

The Constitutional Convention is composed of 155 members directly elected in this election: 138 by the electorate at large and 17 were reserved for citizens identified as indigenous.

The 138 at-large members were chosen in 28 constituencies of between three and eight seats by open list proportional representation. The constituencies are the same used for the election of the 155 members of the Chamber of Deputies. However, the districts with the largest number of indigenous people (according to the last census) and more than 3 seats were reduced by one seat to allocate the reserved indigenous seats.^[11] Candidates should be at least 18 years old and not have been previously convicted of a felony. Candidates could be presented by political parties or alliances of parties; in the case of independents candidates, they could participate as single independent candidates (gathering signatures of other independent citizens equal to 0.2% of voters in the last parliamentary election) or as a list (in this case, 0.5% of voters).^[12]

Seats were allocated using the D'Hondt method, just like in the parliamentary elections. In April 2020, a constitutional reform made some adjustments to that system to ensure equal representation of men and women in the Constitutional Convention. In case there is no gender equality in a constituency,^{[n 1]} the least-voted elected candidate of the over-represented gender will be replaced by a different-sex member in the same list or political party of the replaced candidate. Also, all alliances and parties had to present a list of candidates alternating their gender, starting with a woman, followed by a man, and so on.^[13]

The 17 seats reserved for Chilean indigenous peoples were allocated proportionally, depending on the number of people identifying in the 2017 census: 7 seats for Mapuche,^{[n 2]} 2 for Aymara, and 1 each for the Diaguita, Quechua, Atacameño, Colla, Chango, Rapa Nui, Kawésqar, and Yaghan peoples. Originally, an additional seat was set for the Afro-Chilean tribal group, but the proposal didn't meet the quorum for approval in Congress.^[14] Candidates for these seats must have been registered as a member of one of the recognized indigenous groups with CONADI or have an affidavit declaring that, and have to live in one of the designated regions for each group. Citizens identifying as indigenous could choose one of the ballots: the beige for the at-large election or the green for the reserved seats (with different candidates depending on its group). The candidates with the largest number of votes will be elected and, in case there is no gender equality, the least-voted members of the over-represented gender will be replaced by their alternate candidate of the different gender.^[15]

Each list also had to present candidates with disabilities at least in 5% of their candidacies. Other proposals to allow more diversity in the Constituent Assembly were rejected, including one to secure 5% of the candidacies to people from gender or sexual minorities or to establish 3 electoral districts (with 8 seats) for Chileans living abroad.^[16][17]

Electoral districts

71 lists of candidates were submitted and approved by the Electoral Service (Servel). Three run on all 16 regions of the country, including the three largest coalitions with parliamentary representation. 2 coalition lists and the 3 parties presented candidates in different regions, but not in all the country. Other 63 lists of independent candidates were presented on a district level; however, some of them congregated on a national level, being The List of the People, Non-Neutral Independents, and Constituent Social Movements, three of the main coalition of independent lists presented in several regions. 28 independent candidates run outside lists, acting as individual lists in each district.

In total, 1278 candidacies were presented for the at-large election.
