Encyclopædia Britannica, Ninth Edition/Aberdare
Aberdare, a town of Wales, in the county of Glamorgan, on the right bank of the river Cynon, four miles S.W. of Merthyr-Tydvil. The district around is rich in valuable mineral products, and coal and iron mining are very extensively carried on in the neighbourhood. Important tin-works, too, have been recently opened. Part of the coal is used at the iron-works, and large quantities are sent to Cardiff for exportation. Aberdare is connected with the coast by canal and railway. Owing to the great development of the coal and iron trade, it has rapidly increased from a mere village to a large and flourishing town. Handsome churches, banks, and hotels have been erected, a good supply of water has been introduced, and as public park has been opened. Two markets are held weekly. The whole parish falls within the parliamentary borough of Merthyr-Tydvil. The rapid growth of its population is seen by the following figures: in 1841 the number of inhabitants was 6471; in 1851, 14,999; in 1861, 32,299; and in 1871, 37,774.
