The constituency was set up in 1976 election when the
highest averages method of the
closed party-list proportional representation electoral system was introduced. No change of boundary had been made throughout since 1976. The constituency covers all the
parishes and zone in
Macau. Members have been elected with seats apportioned with a peculiar
highest averages method. While
D'Hondt uses 1,2,3,4,... as divisors, Macau instead uses 1,2,4,8,... as divisors Their method
disadvantages large parties, which is highly unusual among electoral systems. Suffrage was opened to Macau Residents without Portuguese citizenship in 1984. == Background ==
