Singapore is governed as a unitary state without provinces or states. However, for the purposes of administration and urban planning, it has been subdivided in various ways throughout its history. As of 2022, Singapore has a total land area of about , not including its sea area. History Historically, these subdivisions have been based on postal districts, especially during the colonial era. When local elections necessitated the setting up of electoral districts, however, it began to supplement postal districts as an alternative form of local governance, since each electoral district is headed by a member of parliament who represents and speaks for the respective electorates.
