ABOUT THE DEVELOPMENT DATA HUB: METHODOLOGY

The Development Data Hub

The Development Data Hub is the most comprehensive online resource for financial and resource flow data alongside poverty, social and vulnerability indicators. It draws from a range of sources and provides an extensive, open data store. See below for details of the methodology and calculations we have used and to download the data yourself.

How does it work?

It brings together many data sets, enabling you to dig into these through interactive maps, charts and visualisations. It turns complex data around poverty and resource flows into easy to understand robust information and evidence about what is really going on. An accessible and easy to use tool for anyone wanting to know more about how resources are spent and if they are enough to tackle poverty.
