EA Funds are a way of giving effectively within specific cause areas. When you donate to the funds, you decide how to allocate your donation between them, and you pool your donation with many like-minded donors. Cause area experts then decide how to best allocate the pooled donations to the most promising giving opportunities they can find.
You can also use the Funds to donate money to a range of charities, including our Top Charities. It is tax-deductible in the US and UK, and also makes it easier to donate to a number of charities at once.
