Measuring what matters

Most people agree that happiness matters.

You might think it is the only thing that matters.

Over the last 30 years, pioneering academics in economics, philosophy, and psychology have tested and developed reliable measures of happiness and life satisfaction

Today, large population surveys allow us to measure and track wellbeing across the world. We can stop relying on measures of wealth or health as our best guess for how people’s lives are going.

But what is wellbeing and how can we measure it?

You can make a difference

The cost-effective interventions we’ve identified may surprise you.

Our research shows that treating depression in low-income countries is nine times more cost-effective than providing direct cash transfers.

How should we compare the value of extending lives to improving lives? Doing so requires us to make various philosophical assumptions, either implicitly or explicitly. But these choices are rarely acknowledged or discussed by decision-makers, all of them are controversial, and they have significant implications for how resources should be distributed. Read more
