Cardiff Urban Area
Coordinates: The Cardiff Built-up Area or Cardiff Urban Area is the name given to the urban area around Cardiff. The vast bulk of the population and area are contributed by Cardiff which had a population of 335,145 as recorded at the 2011 census. The rest was made up by the towns of Penarth and Dinas Powys connected to the south-east of the city along Cardiff Bay as well as the South Wales Valleys towns of Caerphilly and Pontypridd. The total official population of this urban area was given to be 447,487 in 2011. This was on increase of almost 37% on the 2001 population of 327,706 this was mainly due to Caerphilly and Pontypridd becoming part of the built-up area.

Cardiff Council estimated the population of the unitary authority at 317,500 in 2006.
