Introducing the Evidence Pie
A simple way to understand and use different types of evidence for better decisions.
Why is the Evidence Pie important?
When councils and public services make decisions, they affect people’s health and wellbeing. Good decisions need good evidence—but “evidence” means different things to different people. The Evidence Pie makes it clear and fair by showing all the types of evidence that matter.
What’s in the Pie?
Lived Experience
Real stories and experiences from people in the community.
Professional Knowledge

Facts and figures about people - like age, gender, and trends.
Organisational Data
