What works, and how we know

Other organizations in this area

Funded or formerly recommended by GiveWell. A grant is not a Top Charity rating.

Questions donors ask

What is the most effective charity for deworming?

We don't pick a winner ourselves. No evaluator has published a top rating in this area that we can quote yet. Each charity page shows the figures, the source and how strong the evidence is.

Should I give to one charity or a fund?

Both are reasonable. A fund run by an evaluator lets them direct your gift to where they judge the need is greatest; giving to one charity lets you choose the program yourself.

Are these figures guaranteed?

No. They are evaluators' modeled estimates of the average. Real results can be higher or lower, and evaluators update them as they learn.
