The sources are listed on every chart. The life expectancy data comes from the World Bank (headquartered in Washington, D.C., majority-funded by the US). GDP figures are from the IMF (also DC-based). Democracy scores come from the Economist Intelligence Unit (a British organization). Press freedom is from Reporters Without Borders (Paris-based NGO, independently funded). CO2 data is from the Global Carbon Project. Gun violence stats are taken directly from the Gun Violence Archive, a US nonprofit. Healthcare spending comparisons are from the OECD (funded by its 38 member countries, including the US, Japan, Australia — not an EU institution). The live electricity data comes from ENTSO-E, the grid operators' transparency platform — it's raw generation data, not opinion.

These are not "EU data." If anything, most of the sources are American or international. You're welcome to check any of them — every metric on the site links to its source. That's the whole point.
