Deworming and tropical disease prevention in these developing countries might not be the obvious choice for where to expend your spare holiday cash.

But it might be where your dollar will do the most good.

That’s according to a list of the nine “Top Charities for Dedicating Season” liberated Monday by GiveWell, a nonprofit organization that applies a data-centered approach to ascertaining which aid organizations do the most good for the most people. The outcome is a surprising list of charities with a range of causes that might be unfamiliar to many who want to give, but whose impact is often more immediate.

“We want people to be able to leverage all the time we’ve spend groups together this list so they can make a donation with confidence, ” explains Catherine Hollander, a research analyst with GiveWell.

For the annual map, the group evaluates charities in four categories: 1) transparency, 2) cost-effectiveness, 3) need, and 4) overall effectiveness, before awarding or denying it a spot. To measure cost-effectiveness the group calculates impact on a scale of “lives saved or improved per dollar spent.”

Some of the causes is a possibility overshadow( at the least, in the developed countries ), but they’re wonderful options for those on a tight holiday budget looking to help the most people possible .

This year’s top choices are:

1. Against Malaria Foundation

An organization that purchases and distributes mosquito cyberspaces to families in malaria-afflicted countries.

2. Schistosomiasis Control Initiative

A U.K.-based charity that furnishes Ministries of Health in East, Central, and West Africa with medicines to treat parasitic infections.

3. Malaria Consortium’s seasonal malaria chemoprevention program

A nonprofit that specializes in the prevention and control of malaria, distributing life-saving medications to young children affected by the disease in Africa and Asia.

4. Evidence Action’s Deworm the World Initiative

An organization that supports school-based deworming programs in Africa and South Asia.

5. Helen Keller International’s vitamin A supplementation program

An initiative that monies and provides training to government-run supplement drives in sub-Saharan Africa with the goal of reducing malnutrition and averting blindness and poor eyesight.

6. Sightsavers’ deworming program

An anti-blindness and disability rights organization that operates a deworming initiative in Africa.

7. END Fund’s deworming program

An anti-neglected tropical disease nonprofit that operates a deworming initiative with a special emphasis on Africa.

8. Evidence Action’s No Lean Season program

A program that furnishes no-interest loans to Bangladeshi farmers during annual periods when income is high.

9. GiveDirectly

A nonprofit that allows donors to send fund immediately to those living in extreme poverty via a mobile app.

A key component of the list is attaining sure the programs GiveWell recommends is most effective than merely sending cash to people in need( or as effective, as is the case with GiveDirectly ).

That entails not only building sure they’re cost-effective, but ensuring the intended beneficiaries of the food, medication, fund, and preventative netting actually receive and use them. For the deworming charities, that involves, “going doorway to door and interviewing children to see if they received de-worming therapy, ” explains Isabel Arjmand, likewise an analyst with the organization. Occasionally, GiveWell representatives conduct the on-the-ground examines themselves. Other periods, researchers with the organization analyze data provided by the charities, which is reviewed for reliability.

The list isn’t fully developed, as GiveWell focuses on programs where the data on impact is plentiful and readily available. Initiatives where results are harder to quantify — those that promote women’s rights, LGBTQ equality, racial justice, etc. — aren’t an area of focus. Nor are induces like cancer prevention that disproportionately affects people in the developed countries, where the cost-per-life-improved ratio is far higher. But for anyone who wants to ensure their dollars go to help the world’s neediest people quickly and efficiently, the list is an invaluable tool.

“One thing that for me personally truly connects when I think about giving to causes that I haven’t myself experienced is … ‘What am I actually trying to accomplish, ‘” Hollander says. “For me, it might be to alleviate suffering in general. And then I’m really excited to give to the place that allows me to do that to the fullest extent that I can with my donation.”

Contributions can also be made directly to GiveWell, which distributes the funds among the recommended organizations according to need .
