Census 2021: residents with foreign citizenship only, as a share of the census population. The census predates most 2022–2025 worker arrivals.
The crest identifies the government; the plate frame and strip match the county colour on the map, and a dashed frame means provisional data or data with a source note. County name: tap, hover or focus a banner.
No label: no data, or no room — open the county. Unknown is not zero.
Relief is illustrative, not data about actual buildings.
