The definition of foreign aid is pretty broad. The largest portion of the money goes to health: a third of the U.S. foreign aid budget in 2014, or more than $5.3 billion. The next two biggest portions go toward economic development and humanitarian assistance. Small sums of aid support democratic elections in other countries. A tiny portion goes to protect forests in countries where logging is destroying natural habitats. Some aid funds programs that train local law enforcement to combat drug trafficking. (But no foreign aid goes directly toward another country’s military.)

The vast majority of spending on health goes to HIV/AIDS projects. In 2014, the U.S. spent $3.1 billion on HIV/AIDS — about a fifth of the foreign aid budget. The next two big health categories were “Maternal and Child Health,” at about $530 million, and malaria, at about $470 million. Of all the global health expenditures, a category labeled “Pandemic Influenza and Other Emerging Threats” receives the least funding, about $66 million in 2014. Funding for the U.S. Ebola response counts as emergency assistance and is not included in the budget.

The U.S. spent $2.7 billion — about a sixth of foreign aid money — on economic development in 2014. Economic development mostly includes infrastructure projects, like building roads, expanding electricity and improving phone and Internet access.

Another sixth goes to humanitarian assistance. The majority is earmarked for “Protection, Assistance, and Solutions” — a vague title that refers to caring for refugees who’ve fled from conflicts. The money feeds and houses the refugees and sometimes covers shelter and migration costs. A tiny amount from this category goes toward disaster readiness.

There’s more to foreign aid than the foreign aid budget. First, there’s money for Overseas Contingency Operations, or, more simply, finishing up projects that the U.S. already started. For example, in 2013, the U.S. spent $2.1 billion on foreign aid in Afghanistan, even though only $700 million was allocated in the federal budget. Then there’s emergency assistance, like the aforementioned Ebola. Finally, the private sector often chips in to help build infrastructure, and its contributions are separate from foreign aid. For example, USAID partnered with Coca-Cola to build juicing facilities in Haiti so that locals could turn their mangoes into a marketable product.
