This is a list of cities/towns in South Australia by urban centre population.
Urban Centres and Localities (UCLs) represent areas of concentrated urban development with populations of 200 people or more. Areas in a state or territory that are not included in an UCL are considered to be âÂÂruralâÂÂ. UCLs are not an official definition of towns.
Suburbs of Adelaide are not included, with the exception of Gawler, Mount Barker, Crafers-Bridgewater and Nairne, which can all be seen as semi-rural suburbs but also as separate towns.
<nowiki>*</nowiki>Uraidila and Summertown are recorded separately until 2011 when they are merged.
Local government areas are the main units of local government in Australia. They may be termed cities, shires, councils or other names, but they all function similarly.
