District electoral division

A district electoral division (DED; Irish: Toghroinn ceantair) is a former name given to a low-level territorial division in Ireland. In 1994, both district electoral divisions and wards (the equivalent of district electoral divisions within the five county boroughs) were renamed as electoral divisions (the boundaries and names of the DEDs and wards themselves remained unchanged). In the Republic of Ireland, DEDs are the smallest legally defined administrative areas in the state for which small area population statistics (SAPS) are published from the Census. In the European Union, Local administrative units (LAUs) are basic components of Nomenclature of Territorial Units for Statistics (NUTS) regions. For each EU member country, two levels of Local Administrative Units (LAU) are defined: LAU-1 and LAU-2, which were previously called NUTS-4 and NUTS-5 respectively, until the NUTS regulation went into force in July 2003. The District electoral division is at the level of LAU-2. There are a total of 3,440 electoral divisions within the Republic of Ireland.

District electoral divisions originated as subdivisions of poor law unions, grouping a number of townlands together to elect one or more members to a Poor Law Board of Guardians. The boundaries of district electoral divisions were drawn by a Poor Law Boundary Commission, with the intention of producing areas of roughly equivalent "rateable value" (the total amount of rates that would be paid by all ratepayers in the DED) as well as population. This meant that while DEDs were almost always contiguous, they might bear little relation to natural community boundaries.

The Local Government (Ireland) Act 1898 established a system of county councils and urban and rural district councils and the district electoral divisions were then used to elect members to the district councils, with groups of DEDs combining to elect members to county councils.
