World Population Conspiracy hypothesis
From Kook Science
The World Population Conspiracy hypothesis is an observational theory that the total human population of the planet Earth is substantially less than has been proposed by various authorities and that evidence to the contrary is manufactured by a conspiracy involving such authorities. The corrected figures for the human population range widely, including low figures in the area of 500 million humans, as compared to the 7.78+ billion that is generally asserted by the United Nations and other international bodies. Such corrected figures are based on varying methodologies, including the intuitive sense that there just aren't that many people in the world really.
