The rankings average the Cantril ladder over 2023 to 2025. Scores used by the wiki, as compiled by Atlas & Boots (https://www.atlasandboots.com/?p=12864): the United States 6.816, the United Kingdom 6.694, France 6.586, Germany 6.882, Italy 6.574, Japan 6.130, Canada 6.741 and Australia 6.916. The report finds life evaluations among people under 25 down by almost one point over a decade in the United States, Canada, Australia and New Zealand, and up in most other regions. Its authors associate part of the decline with heavy social media use and state that their data cannot establish causation. The wiki cites it in What GDP Leaves Out for both the decline and that competing explanation.
