Explanation: Parishes as at May 2025. All population and corresponding area figures of parishes are based on assigning output areas by using population-weighted centroids. Thus, slight discrepancies are possible compared to the actual parish boundaries that are depicted in the map. No population figures (and the actual area) are provided for parishes smaller than output areas.
