  1. This table compares the response behaviour in the US random sample of the 2021/2022 Gallup World Poll to the response behaviour in the US online survey in ref. 30 (N = 2,000) for questions that were included in both data collections. See Methods for details about data collection. Shown is the proportion of respondents who are willing to contribute 1% of their income to the fight against climate change (answered yes or no), approve of pro-climate norms (yes or no) and demand more political action from their national governments (yes or no) in both samples. The P values of a t-test for differences in means between the two samples are also shown.
