Method
This page exists because of a Facebook graphic claiming to show "how much tax people pay in Europe" — a few numbers, a black background, no sources, no explanation of what "tax" meant or whose income it was measured against. It was shared widely and treated as evidence. Most of it was wrong. The parts that weren't wrong were still misleading, because a true number with no context can create a false impression as easily as a fabricated one.
This page is the opposite exercise: the same kind of question — how does life cost compare across countries — answered the slow way. Every number here has a named source. Every chart follows the same rules, applied the same way regardless of which country it makes look better or worse. Where the honest answer was "we don't know precisely" or "these countries don't measure this the same way," that's what the page says, instead of picking a number that looked clean.
If you only read one thing on this page, read this section. It explains the rules everything else follows, so you can check our work instead of taking our word for it.
1. Every number has a source you can check. Not "studies show" — a named organization, a named report, a year. Where we used a secondary source (a news outlet citing government data, for instance) instead of the primary document itself, we say so, and we say what we couldn't independently verify.
2. A range gets shown as a range, honestly. Some costs vary — by region, by income, by family size. When we have real data for both ends of that range, we show the whole range, not just an average that could go either way. When we know a range exists but don't have solid numbers for both ends, we say so explicitly rather than guessing. When we have neither, we leave the number out. A guess with a footnote is still a guess.
3. A bar that looks complete should be complete. If a cost is a guaranteed minimum — a fixed fee that doesn't include some extra charges that also apply — the chart says so visually, not just in small print at the bottom. The same goes the other way: if we could only confirm a number is "at least" some amount, the chart shows that, not a fake precise figure that happened to show up in a news article.
4. Cost alone isn't the whole picture — and neither is percentage alone. A dollar figure without knowing anyone's income is close to meaningless; a percentage without the underlying dollar amount hides how big the number actually is. Wherever it's meaningful, this page shows both: what something costs, and what share of a typical income that represents.
5. Colors don't mean "good" or "bad." Each country gets one consistent color across every chart on this page. That color never changes based on whether the number is high or low. A chart that colors "bad" numbers red is making an argument with the color, not the data — we don't do that here.
6. When countries can't be honestly compared on a chart, we don't force it. Some things — like how much of your final salary a pension replaces — are measured completely differently from one country to the next: gross vs. net, by law vs. by convention, sometimes not measured that way at all. Forcing five different measurements onto one bar chart would make them look more comparable than they are. Where that happened, this page uses a table instead, laying out exactly what basis each country's number is on, so you can see the difference instead of having it hidden from you.
7. We checked our own work, and changed it when it didn't hold up. Several numbers on this page went through a second pass against original government and international-organization data after we'd already built the first version of a chart. More than one number got downgraded — from a precise-looking figure to an honest range or a floor — because the second check couldn't confirm the precision the first version implied. We left that process visible rather than quietly fixing it and moving on, because the point of this page is the discipline, not just the destination.
This page is not making the opposite political argument from the original graphic — it's not claiming Europe is better, or that the US is worse, or the reverse. Several of the findings here cut in different directions depending on which specific comparison you look at: the US has the highest net childcare cost of any wealthy country we could find data for, and also the cheapest gas of the five countries compared here. Both of those are true at once, sourced the same way, held to the same standard. A page built on evidence doesn't get to pick which true things to include based on where they point.
Where the data was genuinely uncertain, that uncertainty is part of the finding, not a gap to be embarrassed about. "We don't know precisely, and here's exactly what we do and don't know" is a more honest answer than a confident-looking number that doesn't survive a second look — which is, ultimately, the entire problem with the graphic that started this.
