Rhondda, or the Rhondda Valley, is a former coal mining area in South Wales, previously in Glamorgan, and now a local government district, of 16 communities around the River Rhondda. The Rhondda is actually two valleys – the larger Rhondda Fawr valley (mawr large) and the smaller Rhondda Fach valley (bach small) – so that the singular "Rhondda Valley" and the plural are both commonly used. In 2001, the Rhondda constituency of the National Assembly for Wales had a population of 72,443; while the National Office of Statistics counted the population as 59,602. Rhondda forms part of Rhondda Cynon Taf County Borough and of the South Wales Valleys. It is most noted for its historical coal-mining industry, which peaked between 1840 and 1925. The valleys produced a strong early Nonconformist Christian movement manifest in the Baptist chapels that moulded Rhondda values in the 19th and early 20th centuries. It is also famous for strong masculine cultural ties exemplified in its male voice choirs, sport and politics.
