List of rural and urban districts in Northern Ireland

They were based on the system of district councils introduced in England and Wales four years earlier.

The six administrative counties all included a number of urban and rural districts in 1921, but no boroughs.

As of 1923, when the DEDs were created ahead of the 1924 local elections, there were 653 DEDs, across 64 local authorities (including the 2 county boroughs, 31 rural districts and 31 urban districts).

Groups of DEDs also formed county electoral divisions (CEDs), which elected councillors to the county councils, forming an upper tier of government above the urban and rural district councils.

The entire system of local government in Northern Ireland was overhauled by the Local Government Act (Northern Ireland) 1972, which replaced the county boroughs, administrative counties, urban districts, and rural districts with 26 local government districts.
