EXPLORE · THE UNITED KINGDOM · 650 CONSTITUENCIES

Read the country through its data — and through how that data falls out across place, party, and representation.

Pick a measure. Toggle between the geographic map (true boundaries, but rural seats swallow the urban ones) and the cartogram (one hex per seat, equal visual weight). Pin anywhere to hold seats in reserve — the picker on the left sets the measure; the rail on the right keeps whatever you've pinned.

VIEW
True boundaries — rural seats dominate visually; urban ones are small and easily missed.
GROUP BY
Each seat is coloured by its own value.
HIGHLIGHT
Every seat at full colour.

Click a seat to pin it to the right rail. Click again to unpin. Pins don\u2019t open the constituency page — use the pinned name links for that.

§ 03Context, if you want it.A note on the map

Two views of the same 650 seats. The geographic choropleth shows true boundaries — honest, but rural seats dominate visually and urban ones read as slivers. The cartogram gives each seat one equal-sized hex, which is how a seat votes. Flip between them; they answer different questions.

Colour comes from the statistical measure on the left rail. Hovering reveals the seat and its value; clicking pins it to the right rail for direct comparison. Nothing is aggregated without saying so, and nothing is modelled where a raw number will do.
