Over the last decades there has been a marked increase in the number of global health improvement initiatives sponsored by individuals, governmental agencies, and nongovernmental organizations hailing from many countries in the developed world. This parallels a surge in the resources available to fund these efforts. The World Bank, which allocated $2 million to global health efforts in 1970, had increased its spending to $855 million by 1990. Other data provided by the World Bank show that funding for global health projects continued to expand during the first decade of the 21st century, with the estimated $7 billion spent by all sectors in 2000 almost doubling to more than $13 billion in 2005.
