Evaluation of Givewell Blogs

Thanks to the trust and generosity of our donors, GiveWell raised $616 million in metrics year 2025, an increase of 49% from 2024. We directed $427 million to support outstanding opportunities to do good in 32 countries. We estimate that the programs supported by the funds we directed this year will save an additional 86,000 lives.

We have spent years growing our research capacity and scope to enable us to direct significantly more funding to the most impactful opportunities we can find, and 2025 was a milestone in that ongoing growth. We responded to urgent needs generated by foreign aid cuts, and we continued to find and fund a growing number and a wider range of high-impact ways to help people. We anticipate our total grantmaking is likely to approach or even exceed $1 billion in 2026, and we are working toward a future that could be several times that scale.

And yet, global needs still far exceed available resources. More than four million young children die in low- and middle-income countries every year—and most of those deaths are preventable. As our team works toward our goal of helping people at a much larger scale, we’re grateful to the donors whose support enables us to continue to find and fund highly cost-effective programs that save or improve lives the most.

Thanks to the generosity of more than 30,000 donors, GiveWell raised $415 million and directed $397 million to cost-effective programs in metrics year 2024 (February 2024 to January 2025). We approved 55 grants to 34 organizations working in 22 countries. We estimate that the programs supported by these grants will help around 34 million people who would not otherwise have been reached and will save an additional 74,000 lives.

We’re incredibly grateful to our donors for the trust they place in our research and for their partnership in trying to do the most good we can together. See this blog post and our full 2024 metrics report for more details behind the money we raised, the funds we directed, operational expenses, donor metrics, and the impact we had last year.

Recently, the GiveWell research team has focused on collecting more feedback about our work and processes, such as through our Change Our Mind contest, our Research Council, and by asking donors for feedback. While we typically ask for candid, live feedback from the organizations we work with, we had not previously invited anonymous assessment of our grantmaking process. We know our processes are different from those of many other funders, and we want to make sure our work reflects our values of maximizing global well-being, transparency, truth-seeking, and considerateness.

So, in July 2024, we sent out our first anonymous survey to people we’ve worked with during grant investigations. The survey was sent to 55 individuals representing 40 organizations that participated in a GiveWell grant investigation from January 1, 2022, to March 31, 2024. It focused on their experiences with our process and post-grant follow-up, and also included a few general questions asking for their feedback about GiveWell. We received 32 responses to the survey, a response rate of 58%. Two of the 32 responses were from organizations that did not receive a grant.

Overall, the people who responded to our survey rated their satisfaction with GiveWell’s investigation process as 4.2 out of 5. The highest-rated areas were responsiveness and respectful communication, well-reasoned information requests, and satisfaction with the post-investigation process.

From sports announcers to political pundits to friends gossipping about romantic interests, lots of people make probabilistic predictions about the future. But only some actually follow up to see how well their predictions performed. For instance, you may have heard that weather forecasters predicted that the 2024 hurricane season had an 85% chance of being more active than normal and there would be 17 to 25 named storms. But in September, they were surprised that so far, it had been unexpectedly quiet, with climate change likely affecting weather patterns in ways scientists don’t fully understand.

GiveWell researchers often make forecasts about activities, milestones, and outcomes of the programs and research studies we recommend funding for, as well as decisions that GiveWell will make in the future. For example, we might forecast whether we’ll fund more hospital programs to implement Kangaroo Mother Care programs by 2027, or whether data collected about how many people are using chlorinated water will align with our expectations.

As a way to solicit external feedback on some of our predictions, we just launched a page on Metaculus, an online forecasting platform. Periodically, we will post forecasts there about GiveWell’s research and grants for the public to make their own predictions. Metaculus and other contributors will award $2,250 in prizes to people who leave insightful comments on a select group of forecasting questions. The deadline for comments is December 1, 2024.

In 2022, the most recent year for which data is available and analyzed, GiveWell raised the largest amount of money in our history, over $600 million. We thank our donors for continuing to trust us to find and recommend highly cost-effective giving opportunities. The following table summarizes our funds raised and our funds directed to programs in metrics year 2021 and 2022.

In September, we announced the Change Our Mind Contest for critiques of our cost-effectiveness analyses. Today, we're excited to announce the winners!

We're very grateful that so many people engaged deeply with our work. This contest was GiveWell's most successful effort so far to solicit external criticism from the public, and it wouldn't have been possible without the participation of people who share our goal of allocating funding to cost-effective programs.

Overall, we received 49 entries engaging with our prompts. We were very happy with the quality of entries we received—their authors brought a great deal of thought and expertise to engaging with our cost-effectiveness analyses.

Because we were impressed by the quality of entries, we've decided to award two first-place prizes and eight honorable mentions. (We stated in September that we would give a minimum of one first-place, one runner-up, and one honorable mention prize.) We also awarded $20,000 to the piece of criticism that inspired this contest.

Winners are listed below, followed by our reflections on this contest and responses to the winners.

We're extremely excited to be announcing the Change Our Mind Contest to encourage critiques of our cost-effectiveness analyses that could lead to substantial improvements of our overall allocation of funds. For all the details, see this page.

Cost-effectiveness is the single most important input in our decisions about what programs to recommend, and we believe it's possible that we're missing important considerations or making mistakes that lead us to allocate funding suboptimally. We've been excited to see people engaging with our cost-effectiveness analyses, and we'd like to inspire more of that engagement.

With that in mind, we're inviting you to identify potentially important mistakes or weaknesses in our existing cost-effectiveness analyses and tell us about them!

In 2021, GiveWell directed the largest amount of money in our history, over $500 million, which we believe will be beneficial or life saving to many people in need. We thank our donors for continuing to trust us to find and recommend some of the most highly cost-effective giving opportunities in the world.

Note that this year, we’ve also updated our metrics report to more clearly communicate about our work. Previously, we reported on our "money moved," a metric that tried to provide a composite picture of both the funds we raised and directed in a given year. However, starting with our 2021 report, we'll be reporting on these metrics separately as "funds raised" and "funds directed," which we believe will be simpler and clearer.

The post GiveWell’s 2021 metrics report appeared first on The GiveWell Blog.

2020 was another year of tremendous growth. GiveWell donors contributed over $240 million to our recommended charities (our "2020 money moved"), a 60% increase from the approximately $150 million we directed in 2019. This is part of an exciting, long-term trend. Just a decade ago, in 2010, GiveWell’s total money moved was $1.5 million.

We believe these donations will save tens of thousands of lives and benefit many others. This incredible impact would not be possible without the continued support and generosity of our donors. While our research enables us to identify and recommend highly cost-effective giving opportunities, our donors are responsible for turning those recommendations into real change for some of the poorest individuals in the world.

The post GiveWell’s money moved in 2020 appeared first on The GiveWell Blog.

Our donor community appears to have given significantly more in 2020 than 2019, according to early data on donations we processed.

Growth was strong relative to previous years—even 2019, which also had strong growth—and across many different dimensions. Overall, donations to GiveWell more than doubled in 2020.

We estimate that these donations will collectively save more than 12,000 lives; provide over 2 million deworming treatments to children, leading to an approximate increase in that group's lifetime earnings of more than $21 million; and deliver almost 3,000 cash transfers to low-income households. For simplicity, the impact estimates in this paragraph exclude some donation types, and so don't represent the full impact of donations to GiveWell in 2020.[1]

The post Early signs show that you gave more in 2020 than 2019—thank you! appeared first on The GiveWell Blog.

GiveWell donors contributed over $150 million to our recommended charities in 2019. This is the first year in our 13-year history we have reached this remarkable milestone.

While it is easy to celebrate this large headline figure, we should not lose sight of the transformative impact this number represents, nor should we overlook the compassion and generosity of the donors behind these dollars. We estimate that donations made to our top charities in 2019 will:

• Avert the deaths of between 19,000 and 32,000 people,
• Provide parasitic worm treatments to over 12 million children, and
• Deliver unconditional cash transfers to over 14,000 families.[1]

Each spring, we share our plans for the year. Here, we highlight the work we plan to do in 2020 that is most likely to help us realize our mission of identifying and directing funding to highly cost-effective giving opportunities.((This post does not include a complete accounting of everything we plan to do in 2020. In particular, it does not include work aimed at primarily internal-facing results, such as improvements to internal staff communications.)) We focus on three projects:

1. Expanding into new areas of research.
2. Searching for new, cost-effective funding opportunities in our traditional research areas.
3. Building our donor community.

Sharing our annual plans and publicly reflecting back on them a year later is our typical practice. This year, of course, is atypical. The plans we laid out internally at the beginning of the year have been disrupted by the COVID-19 pandemic. The plans we share in this post take the pandemic into account, but we are more uncertain than usual about what will happen in 2020. We expect that much of our work will go forward as anticipated, but we will be flexible if there are unforeseen disruptions or changes to our research agenda that result from the pandemic.

GiveWell grew significantly in 2019. We hired 13 full-time staff members, bringing our total size to 37, and expanded our ability to take on new projects across domains. We feel positioned to do more and better work going forward as a result.

We see a strong indication that the amount of funding we directed to our recommended charities increased last year, too. While we haven't reconciled all giving from 2019, the value of donations we processed increased by about 30% in 2019.

We're proud of what we accomplished in 2019. We also fell short of some goals last year. Most notably, we failed to make as much progress as we planned in researching new areas of global health and poverty alleviation.

This blog post provides a brief look at our key successes and failures last year. A more detailed accounting of how our progress in 2019 compared to the goals we set is available on this page.

The post Reflecting on our progress in 2019 appeared first on The GiveWell Blog.

We see an early indication that GiveWell continued its trajectory of robust donor growth last year. The total value of donations processed by GiveWell increased 30% in 2019.[1]

We're sharing this data now because we believe it is an informative early update about our growth last year. However, GiveWell-processed donations don't tell the full story of our impact. Many donors who rely on our research give via our partner organizations or directly to our top charities. Their gifts account for the majority of donations due to our work and are not processed by GiveWell. Information about these gifts is time-consuming to gather and has usually led us to release our metrics data many months after the end of the year. We plan to release a complete 2019 metrics report and assessment of our impact, including donations not processed by GiveWell, later this year.

Here's what we know so far, based on the nearly complete information we have about donations we processed:

• We processed $54.1 million in donations in 2019. Sixty-five percent of this amount was restricted to our recommended charities and 35% was unrestricted, which we may use to support GiveWell's operations.
• Support from donors giving $10,000 to $100,000 comprised the largest proportion of our growth (35%).[2]
• Returning donors who gave more than last year made up 75% of our growth in funds donated (excluding anonymous donations).[3]
• We believe that the majority of our growth was organic and would have occurred without any outreach and marketing efforts from GiveWell, although we can attribute some to specific outreach and marketing initiatives.[4]

We're encouraged by this growth and excited to write about it. We also discuss below some ways that GiveWell-processed donations could be a misleading indicator of our overall impact.

The post How did we do in 2019? A preliminary look at our growth. appeared first on The GiveWell Blog.

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 2018 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 2018 data cover February 1, 2018 through January 31, 2019.
• In an effort to present a more comprehensive measure of our influence on charitable giving, this year's metrics report includes GiveWell Incubation Grants in our headline "money moved" figure. In previous reports we have excluded Incubation Grants from this figure.

Summary of influence: In 2018, GiveWell influenced charitable giving in several ways. The following table summarizes our understanding of this influence.

Headline money moved: In 2018, we tracked $141 million in money moved to our recommended charities and via our Incubation Grants program. Our money moved only includes donations that we are confident were influenced by our recommendations.

2018 was a successful year for GiveWell. We achieved most of our goals and our money moved (donations made to our recommended charities due our research) increased significantly.

Each year, we look back at the goals we set the previous year and reflect on how our progress compared to our expectations.

This post will briefly discuss our key achievements and failures in 2018. We describe in detail our progress on the goals we outlined in 2018 here.

In 2018, we:

• Directed an estimated $65 million in donations to our top charities, not including the contributions of Good Ventures, a large foundation with which we work closely.
• Added senior hires in operations and outreach: a Director of Operations (Whitney Shinkle) and Head of Growth (Ben Bateman). We expect Whitney and Ben to make major contributions to our work in these domains.
• Continued to improve and expand our core research product, completing new intervention reports, deepening our analysis for several key inputs into our cost-effectiveness model, and providing more transparent explanations for how we decided to allocate funds between top charities.

The post Review of GiveWell’s work in 2018 appeared first on The GiveWell Blog.

To date, most of GiveWell's research capacity has focused on finding the most impactful programs among those whose results can be rigorously measured. This work has led us to recommend, and direct several hundred million dollars to, charities improving health, saving lives, and increasing income in low-income countries.

One of the most important reasons we have focused on programs where robust measurement is possible is because this approach largely does not rely on subject-matter expertise. When Holden and I started GiveWell, neither of us had any experience in philanthropy, so we looked for charities that we could evaluate through data and evidence that we could analyze, to make recommendations that we could fully explain. This led us to focus on organizations that had impacts that were relatively easy to measure.

The output of this process is reflected in our current top charities and the programs they run, which are analyzed in our intervention reports.

GiveWell has now been doing research to find the best giving opportunities in global health and development for 11 years, and we plan to increase the scope of giving opportunities we consider. We plan to expand our research team and scope in order to determine whether there are giving opportunities in global health and development that are more cost-effective than those we have identified to date.

We expect this expansion of our work to take us in a number of new directions, some of which we have begun to explore over the past few years. We have considered, in a few cases, the impact our top and standout charities have through providing technical assistance (for example, Deworm the World and Project Healthy Children), supported work to change government policies through our Incubation Grants program (for example, grants to the Centre for Pesticide Suicide Prevention and Innovation in Government Initiative), and begun to explore areas like tobacco policy and lead paint elimination.

Over the next several years, we plan to consider everything that we believe could be among the most cost-effective (broadly defined) giving opportunities in global health and development. This includes more comprehensively reviewing direct interventions in sectors where impacts are more difficult to measure, investigating opportunities to influence government policy, as well as other areas.

Making progress in areas where it is harder to determine causality will be challenging. In my opinion, we are excellent evaluators of empirical research, but we have yet to demonstrate the ability to make good judgments about giving opportunities when less empirical information is available. Our values, intellectual framework, culture, and the quality of our staff make me optimistic about our chances, but all of us at GiveWell recognize the difficulty of the project we are embarking on.

Our staff does not currently have the capacity or the capabilities to make enough progress in this direction, so we are planning to significantly increase the size of our staff. We have a research team of ten people, and we are planning to more than double in size over the next three years. We are planning to add some junior staff but are primarily aiming to hire people with relevant experience who can contribute as researchers and/or managers on our team.

GiveWell's top charities list is not going to change dramatically in the near future, and it may always include the charities we recommend today. Our top charities achieve outstanding, cost-effective results, and we believe they are some of the best giving opportunities in global health and development. We expect to conclude that many of the opportunities we consider in areas that are new for us are less cost-effective than those we currently recommend, but we also think it is possible that we will identify some opportunities that are much more cost-effective. We believe it is worth a major effort to find out.

The post How GiveWell’s research is evolving appeared first on The GiveWell Blog.

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 2017 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 2017 data cover February 1, 2017 through January 31, 2018.
• We differentiate between our traditional charity recommendations and the work of the Open Philanthropy Project, which became a separate organization in 2017 and whose work we exclude from this report.
• More context on the relationships between GiveWell, Good Ventures, and the Open Philanthropy Project can be found here.

Summary of influence: In 2017, GiveWell influenced charitable giving in several ways. The following table summarizes our understanding of this influence.

Headline money moved: In 2017, we tracked $117.5 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 nine top charities received the majority of our money moved. Our seven standout charities received a total of $1.8 million.

Money moved by size of donor: In 2017, 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 2017, 90% of our money moved (excluding Good Ventures) came from 20% 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 29% year-over-year to 23,049 in 2017. This included 14,653 donors who gave for the first time. Among all donors who gave in the previous year, about 42% gave again in 2017, up from about 35% who gave again in 2016.

Our retention was stronger among donors who gave larger amounts or who first gave to our recommendations prior to 2015. Of larger donors (those who gave $10,000 or more in either of the last two years), about 73% who gave in 2016 gave again in 2017.

GiveWell’s expenses: GiveWell’s total operating expenses in 2017 were $4.6 million. Our expenses decreased from about $5.5 million in 2016 due to the Open Philanthropy Project becoming a separate organization in June 2017. We estimate that 67% of our total expenses ($3.1 million) supported our traditional top charity work and about 33% supported the Open Philanthropy Project. In 2016, we estimated that expenses for our traditional top charity work were about $2.0 million.

Donations supporting GiveWell’s operations: GiveWell raised $5.7 million in unrestricted funding (which we use to support our operations) in 2017, compared to $5.6 million in 2016. Our major institutional supporters and the six largest individual donors contributed about 49% of GiveWell’s operational funding in 2017.

Web traffic: The number of unique visitors to our website remained flat in 2017 compared to 2016 (when excluding visitors driven by AdWords, Google’s online advertising product).
