The cornerstone of our research

How do we measure happiness?

We use a metric called the Wellbeing-Adjusted Life Year, or WELLBY, which has also been adopted by the UK Treasury and New Zealand government.

You can think of a WELLBY as a year of happiness. More technically, a WELLBY is a one-point increase in wellbeing, on a scale of 0-10, for one person for one year

The Happier Lives Institute has been pioneering the WELLBY since 2019, because it allows us to measure what really matters.

What does happiness mean? The war for the meaning of happiness

This may sound like a faux-intellectual investigation of something that’s obvious. But when I tell people I’m a happiness researcher, sometimes people get this glint in their eyes, probably thinking they’re the first person to ask me: “What does ‘happiness’ even mean?”. I think this is an important, if unoriginal, question. Because […]
