This briefing is based on a rapid evidence assessment of impact evaluations that use the personal wellbeing measures from the Office for National Statistics. These are known as the ONS4. They measure life satisfaction, happiness, our sense of feeling worthwhile (purpose),
and anxiety.

The ONS4 measures are being used across a wide range of intervention types to evaluate effectiveness. These include housing improvement and neighbourhood design; community-centred approaches; and skills training.

This helps to build the broader evidence base on what works. You can send your wellbeing evaluations to evaluation@whatworkswellbeing.org
