The electoral system was changed following the 2018 parliamentary elections amid the 2019–2021 Iraqi protests. Previously conducted under proportional representation calculated using the Webster/Sainte-Laguë method with the governorates as constituencies, the 2021 elections were conducted under single non-transferable vote in 83 multi-member constituencies.[3] The distribution of the number of electoral districts in each governorate relies on the number of quota seats for women multiplied by 3 or 5 seats for the electoral district depending on the governate's population size. One-quarter of total seats are reserved for women in the constituencies, while nine are reserved for minorities (5 for Christians and 1 each for Yazidis, Shabaks, Mandaeans and FeyliKurds).[4][5]
