1908. Caerphilly Urban District and Gelligaer Urban District were abolished in 1974, with both areas becoming part of Rhymney Valley District, being the first time that a district-level authority had covered all of Ystrad Mynach. Communities were established to replace the old parishes at the same time, with the communities initially using the boundaries of the abolished urban districts, and so Ystrad Mynach straddled the communities of Gelligaer and Caerphilly. The community boundaries were amended in 1985 to put Ystrad Mynach entirely within the community of Gelligaer. The Office for National Statistics defines Ystrad Mynach as a built-up area sub-division within the wider Newport built-up area. The Ystrad Mynach sub-division covers Ystrad Mynach itself and Gelligaer, Hengoed, Maesycwmmer, and Penpedairheol, and had a population of 19,204 at the 2011 census. For postal purposes, Ystrad Mynach is not considered a post town, but instead comes under the Hengoed post town, CF82. Gelligaer Community Council calls Ystrad Mynach a town, whereas all the other places it covers (including Hengoed) it calls villages.
