Each of the nine provinces is governed by a unicameral legislature, which is elected every five years by party-list proportional representation. The legislature elects a Premier as head of government, and the Premier appoints an Executive Council as a provincial cabinet. The powers of provincial governments are limited to topics listed in the Constitution; these topics include such fields as health, education, public housing and transport.
The provinces are in turn divided into 52 districts: 8 metropolitan and 44 district municipalities. The district municipalities are further subdivided into 226 local municipalities. The metropolitan municipalities, which govern the largest urban agglomerations, perform the functions of both district and local municipalities.
