ABSTRACT
We explore the relationships between subjective well-being and income, as seen across individuals
within a given country, between countries in a given year, and as a country grows through time.
We show that richer individuals in a given country are more satisfied with their lives than are poorer individuals,
and establish that this relationship is similar in most countries around the world.
Turning to the relationship
between countries, we show that average life satisfaction is higher in countries with greater GDP per
capita. The magnitude of the satisfaction-income gradient is roughly the same whether we compare
individuals or countries, suggesting that absolute income plays an important role in influencing wellbeing.
Finally, studying changes in satisfaction over time, we find that as countries experience economic
growth, their citizens’ life satisfaction typically grows, and that those countries experiencing more
rapid economic growth also tend to experience more rapid growth in life satisfaction.
