For local government purposes, Wales is divided into 22 unitary authorities. There are 9 counties, 3 cities1, and 10 county boroughs, although all have equal powers. Collectively these are known as the principal areas of Wales. They came into being on April 1, 1996 by virtue of the Local Government (Wales) Act 1994 (1994 c. 19).
1: There are five cities in total in Wales â€" in addition to the three unitary authorities with city status, the communities of Bangor and St David's also have the status of a City.
Areas are Counties, unless marked * (for Cities) or † (for County Boroughs). Welsh language forms are given in parentheses, where they differ from the English.
From 1889 to 1974, administrative counties of Wales were used for local government for the first time. These were created by the Local Government Act 1888 (51 & 52 Vict, c. 41) based on the traditional counties of Wales, but they were not entirely identical.
In 1974, the existing administrative counties were abolished and replaced by eight new two-tier authorities, instead called 'counties' by the Local Government Act 1972 (1972 c. 70). These were all given names in Welsh only, apart from the three in Glamorgan, which had English names as well as Welsh. The creation of these new administrative areas effectively separated the administrative function from the traditional counties, although in reality this had occurred in 1889.
When these two-tier counties were abolished in 1996, their names and areas were retained with slight modifications for some purposes such as Lieutenancy, and became known as the preserved counties of Wales. These were further amended in 2003 by S.I. 2003/974 to ensure that each unitary area is wholly within one preserved county.
