Explore the Atlas

ATLAS is built around countries. Each one with election data has the same five pages, so once you know one country, you know them all. Here's what's on each, with Portugal as the example.

A country's pages

Overview

Start here
The country at a glance: a map coloured by our projection or by the last election, the parliament it gives, who governs, and when the next election is. The switch at the top changes between projection and last election.

Elections

Every election we have, on the map. Pick a year, click a district to see its result, then click again to go down to its smallest areas. The 1st, 2nd… buttons colour the map by the winner, the runner-up and so on.

Projection

Our polling average and the seats it would give, how it moved over time, and every poll behind it. Any poll or the projection can be downloaded as an image to share.

Simulator

Type your own national shares and see the parliament they'd elect, district by district, using the country's real rules. Start from the last election or from our projection.

Beyond one country

Countries

Every country, searchable and filtered by region. Those with election data come first; the others already have their maps, and many have polls.

Latest Elections

The most recent results across the countries we cover, and the national elections coming up next.

Small things worth knowing

Pointing at anything (a district, a seat, a party in a list, a line in a chart) shows its numbers. In the parliament diagrams, pointing at a party in the list lights up its seats, and the other way round.

Bright or dark: the site has both. Switch under Settings, at the top right.

Colours follow each party's own, lightened or darkened just enough to read well on either background.
