Charity mission.jpg

“Evidence Action scales proven, rigorously evaluated development solutions to benefit millions of people around the world.”

Where they work

Kenya, Liberia, Uganda, Malawi, India, Pakistan, Nigeria

Theory of change

“We bridge the gap between rigorous research and pilot interventions on one hand, and institutionalized programs on the other. By focusing on promising approaches backed by rigorous evidence, we support programs that are measurably effective; by seeking to solve the challenge of scale, we provide cost-effective impact for many.”

What they do
  • Deworm the World: combats worm infections by working with governments to deliver mass school-based deworming programs.

  • Dispenser for Safe Water: a network of low-cost chlorine dispensers that improves local water quality.

  • Evidence Action Accelerator: new program development.

Deworm the World

A 2021, 20-year study determined that children who received two to three additional years of deworming increased their income by 13% and consumption by 14% two decades after treatment.

  • A 2016 NBER meta-analysis found that deworming programs lead to an average weight gain of 0.3kg in children, equivalent to moving a three-year-old from the 25th to the 50th percentile of WHO child growth standards.

  • A 2015 study concluded that children who were less than one year old when their siblings received deworming treatment showed significant cognitive gains comparable to between 0.5 and 0.8 years of schooling.

  • A 2004 RCT found that children who received deworming had a 25% reduction in school absenteeism, when compared to those who did not.

  • Previously a GiveWell recommended charity from 2013-2022; GiveWell concluded that “We believe that there is strong evidence that administration of deworming drugs reduces worm loads but weaker evidence on the causal relationship between reducing worm loads and improved life outcomes.”

  • Currently a “Best Charity” for The Life You Can Save, which notes that “Deworm the World’s work has helped contribute to significant declines in worm prevalence in Kenya, and emerging evidence from India indicates that success in reducing prevalence is being achieved there as well.”


Dispensers for Clean Water

  • A 2019 study tested point-of-collection chlorine dispensers against a variety of other water treatment interventions and found that dispensers had much higher usage rates and usage stayed high over time.

  • A working paper from the University of Chicago shows that water treatment reduces all-cause under-five mortality by around 25%. They also analyzed cost data from Dispensers for Safe Water and estimate that the number of DALYs averted per dollar is more than 45 times greater than the WHO’s threshold for “highly cost-effective” interventions. “This puts water treatment in a similar company to micronutrient interventions, insecticide-treated malaria bed-nets, and routine childhood vaccinations in terms of their impact on child health.”

  • The Life You Can Save notes that “Dispensers for Safe Water’s focus on behavioral change yields chlorine adoption rates that are five times higher than other water treatment solutions, and are sustained over time.”

  • Deworm the World: over 1.3 billion treatments delivered since 2014 for less than US0.50 per treatment

    • 275 million annual treatments delivered

    • Access to safe water for less than $1.50 per person
