<P> The "Day of Seven Billion" was targeted by the United States Census Bureau to be in March 2012, while the Population Division of the United Nations suggested 31 October 2011, and the latter date was officially designated by the United Nations Population Fund (UNFPA) as the approximate day on which the world's population reached seven billion people . United Nations Secretary General Ban Ki - moon spoke at the United Nations building in New York City on this milestone in the size of world population, and promoted the website 7 Billion Actions . Ban Ki - moon did not choose a symbolic seven billionth baby, but several groups proposed candidates: Nargis Kumar of Uttar Pradesh, India, Danica May Camacho of Manila, Philippines and Wattalage Muthumai of Colombo, Sri Lanka . </P> <P> National or subnational governments have sometimes made similar designations based on the date estimated by a demographic agency . Some national milestones relate to citizens rather than residents . Commentators in countries with high immigration have pointed out that a population milestone may be reached by an immigrant rather than natural increase . </P> <Table> <Tr> <Th> Country / nationality </Th> <Th> Population </Th> <Th> Born (date) </Th> <Th> Name and surname </Th> <Th> Notes </Th> <Th> Foot - notes </Th> </Tr> <Tr> <Td> Munich </Td> <Td> 1m </Td> <Td> 15 December 1957 </Td> <Td> Thomas Seehaus </Td> <Td> Awarded by Mayor Thomas Wimmer with a 1,000 mark savings account . </Td> <Td> </Td> </Tr> <Tr> <Td> United States </Td> <Td> 200m </Td> <Td> 20 November 1967 </Td> <Td> Robert Ken Woo Jr </Td> <Td> Named by Life magazine, not the government .
