A persistent cluster of claims links Bill Gates to depopulation or eugenics agendas, most commonly by citing his 2010 TED talk in which he discussed the relationship between healthcare, reproductive services, carbon emissions, and global population growth. In its most common form, the claim misrepresents Gates's actual argument: that improving healthcare and education in developing countries historically correlates with declining birth rates (demographic transition theory). The Bill & Melinda Gates Foundation's published focus areas — vaccines, maternal health, agricultural productivity — are oriented toward reducing child mortality and improving living conditions, not population reduction. More extreme variants allege Gates Foundation vaccines are covertly designed as depopulation tools; this framing carries antisemitic-adjacent structural patterns that the ADL has documented. All variants have been repeatedly fact-checked as false or unsupported by Reuters, AP, and Politifact.
