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 at the 2011 census. The rest was made up by the towns of Penarth and Dinas Powys, connected to the south-west 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 an 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. The population of the Cardiff unitary authority (not co-terminous with the built-up area or the wider urban area) in 2001 was 305,353. Cardiff Council estimated the population of the unitary authority at 317,500 in 2006; at the 2011 census it was 346,090.

Nantgarw is a village in the county borough of Rhondda Cynon Taf, Wales, near Cardiff.

From an electoral and administrative perspective Nantgarw falls within the ward of Taff's Well, a village some 2+1⁄2 miles (4 km) south, but historically fell within the boundaries of Caerphilly, which is a major town located less than 2+1⁄2 miles (4 km) to the east.

The COVID-19 pandemic was confirmed to have spread to Wales on 28 February 2020, with a case being reported in the Swansea area; this first known case was a person who had recently returned from Italy. The first known case of community transmission was reported on 11 March in the Caerphilly area.

Wide-ranging restrictions began on many aspects of life in the second half of March 2020; restrictions were relaxed in Wales during the summer once the first wave of the virus had passed. In the autumn of that year, with cases rising, restrictions began to be tightened again with individual areas being placed under localised lockdowns. A two-week complete "circuit-breaker" lockdown began in late October. Rising cases and a new variant of the virus led to restrictions being increased again in December. The rollout of COVID-19 vaccinations and a fall in cases led to restrictions being relaxed in the spring and summer. Restrictions were briefly tightened and relaxed at around the end of 2021 due to a new variant of the virus. Most COVID-19 related legal restrictions concluded in Wales by the end of March and much of the infrastructure built up around managing the virus was wound down by the middle of 2022.

The river formed the boundary between the historic counties of Glamorgan and Monmouthshire until in 1887, the parishes east of the river, Rumney and St Mellons, were transferred from the jurisdiction of Newport, to Cardiff in Glamorgan.

The river flows south from its source near Rhymney through New Tredegar, Bargoed, Ystrad Mynach, and Llanbradach to Caerphilly at the southern end of the Rhymney Valley. Then past Bedwas, Trethomas, Machen, Draethen, Llanrumney and Rumney and its estuary into the River Severn.
