British politics as Tetris

I’ve only just come across a remarkable website, Electoral Calculus which ‘predicts the next British General Election result using scientific analysis of opinion polls and electoral geography’. The mathematical detail of it all only serves to remind me how much of my Maths A-Levels I’ve now forgotten.

But the most striking thing on the site, and one I’m quite inspired by, is their constituency map. Each constituency is drawn to be the same surface area, as they are all roughly the same population (70,000 ish). And startlingly, it’s all done as an HTML table with background colours on the cells.

The overall effect is something very close to Tetris. But it still looks appreciably like a map of Great Britain, and it would make a great basis for some election-night online maps. It may not be too early to start thinking of this.
