As a component of Part 2 of our European Parliamentary Elections from 2008 to Present project, which will be posted next week, the team at Trendency thought this chart was fascinating enough to share as a standalone post. This chart looks at two kinds of political and ideological change: direction and volatility. Across 15 European countries and 83 national parliamentary elections, the horizontal axis illustrates direction: whether a country’s parliament has moved left or right over time (from the 2008 financial meltdown to present). The vertical axis measures how much a country has bounced around ideologically between each election. Importantly, the left–right axis does not indicate whether a country’s parliament currently sits on the left or right. It displays movement. A country can be positioned politically as left- or right-leaning overall but still appear near the center if its parliament did not move dramatically over the time period studied. Some countries have moved clearly rightward, some have moved only modestly in either direction, and others have swung back and forth without settling into one clear direction. The core takeaway: ideological change is not just about who moved left or right, or by how much. It is also about whether that movement has been steady or chaotic. 
Key Takeaways: 

➡️ / 📈 The rightward shift is real, but uneven: Italy stands out as the clearest case of sustained rightward movement, landing farthest to the right on the horizontal axis. It also sits relatively high on the volatility axis, suggesting that this was not just a quiet, gradual drift to the right, but a broader trend accompanied by substantial election-to-election movement. Greece also exhibits notable movement, but in a different way: although it falls just short of this chart’s threshold for a clearly directional rightward shift, it’s one of the more erratic countries in the data, reflecting a political system that has moved substantially across its 8 elections, even if its overall direction is less stark. Germany, Austria, France, and the Netherlands also fall on the right-moving side of this chart, but they sit lower than Italy and Greece on the volatility axis, meaning their movement was more gradual from election to election. Put simply, these countries demonstrate evidence of rightward movement, but not the same combination of sharp direction and high churn seen in Italy, or the same degree of back-and-forth movement seen in Greece. 

🌪️ / 🪃 Volatility and direction are not the same thing: Bulgaria is the chart’s clearest case of political whiplash. Across 12 elections (the highest number of any country examined here), Bulgaria moved sharply from election to election without producing the same clear ideological trajectory as the next-most turbulent country, Italy. In that sense, it is more comparable to Greece: both Bulgaria and Greece sit high on the vertical axis, but neither land as far right on the horizontal axis. Bulgaria’s pattern captures what can happen when a country repeatedly swings in different directions. These pivots can partly cancel each other out: dramatic movement in one election, followed by an opposing movement in the next, can produce high volatility but a more modest, or stable-appearing, overall trend. Bulgaria’s situation helps underscore why looking only at the beginning and end points can miss much of the story in between. 

🪨 / ⛰️ / ⚓ / 📏 Some countries have been comparatively stable: Countries like Denmark, Belgium, Hungary, and France sit lower on the vertical axis of this chart, meaning their parliaments moved less dramatically between elections, even if their overall trajectory still tilts toward the left or right. In other words, this is a point about volatility, not ideology: lower on the chart does not necessarily suggest more moderate, more centrist, or less politically contentious. Hungary is a useful example here. Its position should not be read as saying Hungarian politics are steady or centrist. Rather, it suggests that its parliamentary composition and resulting ideology have not jumped around as sharply between elections, compared to some others’. The broader pattern is not one of a single European political earthquake, but a mix of sharp rightward shifts, capricious swings, and smaller, more consistent movements.
