The U.S. provides more assistance than any other country. As the worlds wealthiest nation, thats appropriate. There is a broad international commitment that wealthy countries should provide annually 0.7 percent of GNP to assist poor countries. Five countries (Norway, Sweden, Luxembourg, Denmark, and the U.K.) exceed that benchmark. The average for all wealthy nations is around 0.4 percent. The U.S. ranks near the bottom at below 0.2 percent.
The U.S. government requires regular monitoring and reporting on how and whether assistance programs are working, and periodic evaluations of results. There is hard evidence that development and humanitarian programs produce considerable results, less so for programs driven for foreign policy and security purposes. While U.S. assistance is by no means the sole driver, the record of global development results is impressive. These results include:
Extreme poverty has fallen dramatically over the past 30 yearsfrom 1.9 billion people (36 percent of the worlds population) in 1990 to 736 million (10 percent) in 2015
Maternal, infant, and child mortality rates have been cut in half
Life expectancy globally rose from 65 years in 1990 to 72 in 2017
Smallpox has been defeated; polio eliminated in all but two countries; deaths from malaria cut in half from 2000 to 2017
The U.S. PEPFAR program has saved 17 million lives from HIV/AIDS and enabled 2.4 million babies to be born HIV-free.
