Map of the United Kingdom by local authority, one number per council area, with the region borders

About this template

Data: one row per local authority district (361 across the UK: English districts and unitaries, Scottish council areas, Welsh principal areas, Northern Irish districts) with its ONS GSS code (E06000001 for Hartlepool, S12000033 for Aberdeen City) or its name, and a number. A district with no row stays grey. The region and nation borders are drawn on top so the districts read inside them. Orkney and Shetland are drawn east of the mainland, at their own scale. Same design as the nation, region and constituency maps.

A choropleth map of the regions of the "uk-local-authorities" geography, each region filled by one number from your data (the "population" column). The borders of UK's regions are drawn on top of the regions in dark navy blue, 0.5 units wide, so the finer regions read inside their larger units.

A sequential colour scale from pale blue for the smallest values to deep navy blue for the largest; pinned to 50000 to 500000, so values beyond the ends take the end colour and the colour bar says ≤ and ≥; a gradient colour bar below the map, with its labels underneath; values formatted in compact form (1.2k, 3.4M), 1 decimal; on a white canvas (#ffffff) with near-black text — a light theme; 0.25-unit hairline outlines between regions.

The title and description are left-aligned above the chart. Font: Inter (the default); a source line with a link sits at the bottom, with the chartlink badge in the corner.

Data: 2 columns — authority (string, "Local authority (ONS code or name)"), population (number, "Population, mid-2024 estimate") — and 361 rows in the example "Population by local authority, 2024". Regions are named by ISO 3166-2 region codes or region names; a region with no row stays unfilled in grey, and an unknown code fails loudly with the nearest matches. Your data keeps the same column ids and every other setting comes from the template; an agent can change any of them.
