The recent history of sterilization programs, both voluntary and involuntary, has seen certain countries, demographics, and skin colors specifically targeted for depopulation. Sometimes the process is slow, through drugs, vaccines, famine, and low fertility. Other times the process is accelerated through wars, economic collapse, and sterilization programs.
The United States embarked on an official policy of depopulation through sterilization after the submission of the National Security Study Memorandum 200 (aka The Kissinger Report) in late 1974. With $140M in funding the following year to implement the program across 13 countries that had been slated for destruction under the Malthusian leadership of Heinz Kissinger, NGOs such as the World Health Organization and UNICEF went to work thinning the herd in Africa, the Middle East, and South Asia.
