The City and County of Cardiff is a county in the south-east of Wales. It is one of the 22 principal areas of Wales.
Communities are the lowest tier of local government in Wales. Unlike English counties, which often contain unparished areas, all Welsh principal areas are entirely divided into communities.
There are 36 communities in Cardiff, with Pentyrch being the largest and Grangetown the most populated. Six of them have a community council.
