The Republic of Macedonia is divided into six electoral units, from which votes for the members of the Macedonian Assembly are processed.
From each unit, 20 members are chosen for a seat in the 120-member Assembly. These 20 members are chosen based on the proportion of votes given to a particular party; the more votes a party receives, the more seats in parliament it occupies.
