The Cantril ladder serves as a proxy for life satisfaction. Life satisfaction is a powerful measure of the quality of people’s lives. The annual World Happiness Reports attributes the differences over time and between countries to good health, income and the quality of the social environment. These factors are changing under COVID-19, often in ways we have never experienced before. The YouGov life satisfaction data, collected regularly as the pandemic evolves in each survey country, provides a valuable barometer reading of life under COVID-19, reflecting each country’s institutions and policies.
