Questions donors ask
- What is the most effective charity for safe water?
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.
