ABOUT THE Evidence & Gap Maps
Our Evidence and Gap Maps bring together evidence on homelessness interventions from around the world to highlight where evidence does or doesn’t exist on what works and why they work or not. This helps target research investments faster and in a more strategic, impactful way.
The Effectiveness Map, or ‘what works’ map - captures impact evaluations and effectiveness reviews. The Implementation Issues or ‘why things work or not’ map focuses on the factors that impact on the successful implementation of homelessness interventions. Together the two maps capture around 600 studies on interventions – the largest resource of its type anywhere in the world.
These EGMs have been created with our partners at The Campbell Collaboration and Heriot-Watt University. Both will be updated at regular intervals. The Effectiveness map has now been categorised to show how much confidence we can have in the findings: high, medium and low confidence.
The Effectiveness Map
Also known as the ‘what works’ map. Explore it to find 394 quantitative impact evaluations and effectiveness reviews of homelessness interventions. It has now been categorised to show how much confidence we can have in the findings: high, medium and low confidence.

The Implementation Issues Map
Also known as the ‘why things work or not’ map. Use it to find 275 qualitative process evaluations that examined factors which help or hinder the successful implementation of homelessness interventions. At the moment the information is displayed in two digital tools – one on barriers and another on facilitators – but an integrated version will be available in future.
