Growing evidence supports the need to re-evaluate the nature and function of our economies in favour of post-growth principles if we are to have a socially and environmentally viable future. This study contributes to the discussion on how to achieve such a future by addressing a remaining gap in the literature about the public acceptance of post-growth, since a viable transition requires public support to validate political actions. Taking a mixed-methods approach, we ask which values and socio-economic characteristics are associated with support for post-growth and why. On average among 34 European countries, 60.5 % of people are in favour of post-growth. Values such as environmentalism, collectivism and post-materialism were found to support post-growth visions of the future, but support for post-growth and these values is lower among disadvantaged people. We conclude that greater emphasis on redistribution and improving opportunities and livelihoods for disadvantaged people in a post-growth economy is key to making such a future more acceptable to them. However, this conflicts with policy preferences and values such as hierarchy, meritocracy, and individualism that tend to be more prominent among people who are well-off. •There is a majority in favour of post-growth within European countries.•Support is highest among high-income, educated and left-leaning individuals.•Post-materialist, collectivist, and pro-environmental values increase support.•Potential policy trade-offs exist as a result of value differences between groups.•Post-growth support could increase with a shift in focus to wellbeing benefits.
