This is a list of localities in Wales by order of population according to the 2011 census data. Major urban areas are sub-divided to provide results about localities within them. Sub-divisions often follow the boundaries of local authorities existing before re-organisation in 1974, or the boundaries of current authorities within agglomerations. The figures in this list include only single localities or subdivisions; they are not the population of local authority areas, electoral wards, or urban areas.
