In Wales, communities are the Welsh equivalent of civil parishes—the lowest tier of local government. Every part of Wales lies within a community, though only some have an elected community or town council. Where they exist, these councils handle very local matters and speak for residents to the county or county borough council. Like English civil parishes, communities are purely civil/administrative and are distinct from church parishes.
