Global well-being in coming decades hinges on non-material factors
To improve people’s well-being as much as possible in coming decades, policy makers should look beyond narrow economic calculations and prioritize non-material factors when making big decisions.
That’s the takeaway from a study, published Jan. 11 in Nature Communications, which draws on global well-being surveys over the past decade to project potential levels of world happiness in 2050. The findings, by a pair of researchers at Ď㽶ĘÓƵ in Canada and the Universitat Autònoma de Barcelona (UAB) in Spain, highlight the critical role of non-material factors such as social supports, freedoms, and fairness in determining the future of human well-being.
“Long-run policies that are overly focused on economic growth will have limited effects on well-being,” says lead author Christopher Barrington-Leigh, an associate professor at McGill’s Institute for Health and Social Policy and the McGill School of Environment. “If human well-being is the main goal of governments, their resources would be more wisely spent based on what really matters most for human experience."
Barrington-Leigh and co-author Eric Galbraith, of UAB’s Institute of Environmental Science and Technology designed a statistical model that combines two sets of measures:
- objective material indicators, including GDP per capita and life expectancy;
- social indicators, as measured in the annual of recent years; these include freedom to choose what to do with one’s life, perceived levels of government and business corruption, prevalence of donating, and availability of informal social supports.
The global survey data showed that, on a scale of zero to 10, respondents on average rated their own well-being at 5.24 in 2016.

The researchers used observed changes in the data from 2005 to 2016 to project scenarios for self-reported life evaluations in 2050.
The results show that future changes in material variables, as projected by the OECD, are likely to yield modest improvements in global average life evaluations – an increase of zero to 10% above current levels. (The OECD projections use two global economic scenarios, devised to explore possible futures for major environmental challenges including climate change.)
By contrast, scenarios based on non-material variables show a wide range of possible outcomes, from a 30% rise in future global average life evaluations in the most optimistic scenario, to a 35% drop in the most pessimistic scenario of societal decline.
“Feasible changes in GDP are very unlikely to play an important role in changes in life self-evaluations within 30 years,” says Galbraith, who was previously based in McGill’s Department of Earth and Planetary Sciences.
“Our results show that the greatest benefits to be potentially made over the next decades, as well as the most dangerous pitfalls to be avoided, lie in the domain of social fabric,” the researchers conclude.
