Who It's For

See electoral systems at work instead of reading about them: the same votes, different rules, different parliaments. The simulator makes it hands-on.

Results down to the smallest areas, a polling average with every poll listed, and images ready to download and share, with their sources.

Decades of results on one map, the same way for every country, with the method behind the projection explained in full.

Follow every new poll, watch the projection move week by week, and test your own scenarios in the simulator.

Before an election: who's running, how they're polling, and what the result could mean for who governs.

A free, visual way to show how elections work, from a single district's count to a whole parliament.
