In England and Wales they were created in 1894 along with urban districts. They replaced the earlier system of sanitary districts. Rural districts had elected rural district councils, which inherited the functions of the earlier sanitary districts, but also had wider authority over matters such as local planning, council housing, and playgrounds and cemeteries. Matters such as education and roads were the responsibility of county councils. Until 1930 the rural district councillors were also poor law guardians for the unions of which they formed part. Each parish was represented by one or more councillors. Originally there were 787 rural districts in England and Wales, as they were based directly upon the sanitary districts and poor law unions which had preceded them. Gradual urbanisation over the following decades led to some rural districts being redefined as urban districts or merging with existing urban districts or boroughs. Other rural districts proved to be too small or poor to be viable, and under the Local Government Act 1929, 236 rural districts were abolished and merged or amalgamated into larger units. Further mergers took place over following decades and by 1965 the number of districts had been reduced to 473. The typical shape of a rural district was a doughnut-shaped ring around a town. A good example of this is Melton and Belvoir Rural District, which surrounded the town of Melton Mowbray. Some rural districts were fragmented, consisting of a number of detached parts, such as Wigan Rural District. Some rural districts had a more rounded shape and had a small town or village as the administrative centre. A few rural districts consisted of only one parish. In such districts there was no separate parish council, and the rural district council exercised its functions. All rural districts in England and Wales were abolished in 1974 and were typically merged with nearby urban districts or boroughs to form "districts", which included both urban and rural areas. See Rural districts formed in England and Wales 1894–1974 for the districts created in 1894; List of rural and urban districts in England, and List of rural and urban districts in Wales for a list of rural districts at abolition in 1974.
Ireland
In Ireland, rural districts were created in 1898 by the Local Government Act 1898. They were subdivided into district electoral divisions. Following the partition of Ireland, rural districts in the Irish Free State were abolished in 1925, by the Local Government Act 1925, amid widespread accusations of corruption. Their functions were transferred to the county councils. The former boundaries of the rural districts in the Republic of Ireland continue to be used for statistical purposes and defining constituencies. In Northern Ireland, rural districts continued to exist until 1973 when they were abolished and replaced with a system of unitary districts.
