Boundary delimitation (or simply delimitation) is the drawing of boundaries, particularly of electoral precincts, states, counties or other municipalities. In the context of elections, it can be called redistribution and is used to prevent unbalance of population across districts.
The Electoral Commission of Zambia is mandated by the Constitution to conduct delimitation of provinces and electoral boundaries. Delimitation is the process of drawing electoral boundaries of constituencies, wards and polling districts.
Article 58 (4) of the Constitution of Zambia states that the Electoral Commission shall determine the names and boundaries of constituencies and wards and section (5) of article 59 states that the Electoral Commission shall, at intervals of not more than ten years, review the names and boundaries of constituencies and wards.
Further, Article 59 of the Constitution of Zambia stipulates the factors the Electoral Commission take into account when delimiting the boundaries of constituencies and wards.
