# GiveWell’s money moved and web traffic in 2016

In September 2017, we posted an interim update on GiveWell’s 2016 money moved and web traffic. This post summarizes the key takeaways from our full 2016 money moved and web traffic metrics report. Note that some of the numbers, including the total headline money moved, have changed since our interim report. Since then, we decided to exclude some donations from our headline money moved figure (details in the full report), and we corrected some minor errors.

This report was highly delayed (as discussed in the interim update). We expect to publish our report on GiveWell’s 2017 money moved and web traffic much more quickly; our current expectation is that we will publish that report by the end of June.

GiveWell is dedicated to finding outstanding giving opportunities and publishing the full details of our analysis. In addition to evaluations of other charities, we publish substantial evaluation of our own work. This post lays out highlights from our 2016 metrics report, which reviews what we know about how our research impacted donors. Please note:

• We report on “metrics years” that run from February through January; for example, our 2016 data cover February 1, 2016 through January 31, 2017.
• We differentiate between our traditional charity recommendations and our work on the Open Philanthropy Project, which became a separate organization in 2017 and whose work we exclude from this report.
• More context on the relationship between Good Ventures and GiveWell can be found here.

Summary of influence: In 2016, GiveWell influenced charitable giving in several ways. The following table summarizes our understanding of this influence.

Headline money moved: In 2016, we tracked $88.6 million in money moved to our recommended charities. Our money moved only includes donations that we are confident were influenced by our recommendations. Money moved by charity: Our seven top charities received the majority of our money moved. Our six standout charities received a total of$2.9 million.

Money moved by size of donor: In 2016, the number of donors and amount donated increased across each donor size category, with the notable exception of donations from donors giving $1,000,000 or more. In 2016, 93% of our money moved (excluding Good Ventures) came from 19% of our donors, who gave$1,000 or more.

Donor retention: The total number of donors who gave to our recommended charities or to GiveWell unrestricted increased about 16% year-over-year to 17,834 in 2016. This included 12,461 donors who gave for the first time. Among all donors who gave in the previous year, about 35% gave again in 2016, down from about 40% who gave again in 2015.
