Giving What We Can carried out research about poverty reduction until July 2016. This page is an archive of research that was done before that time.

These pages summarise how some interventions work, and the conclusions of our research into their effectiveness. For more information on our methodology, see our page on How We Assess Charities.

Our research has been especially focused on evaluating health-related organisations, because there are comprehensive statistics and data available for assessing their cost-effectiveness, and because our research shows that the most effective aid interventions are likely to be health-focused. However, we also consider many other promising areas, like agricultural research or climate change mitigation.


We owe a lot to our high quality sources. Our biggest source of information, particularly for determining our charity recommendations, is the US charity evaluator Givewell. Their rigorous research methodology focused on determining the overall good done by programs, combined with a strong commitment to transparency and the resources to investigate charities extremely thoroughly, make them an invaluable resource for determining the best charities to donate to.
