what is the total population of the world since creation
World population estimates Estimates of the "total number of people who have ever lived" is 107.6 billion as of 2011.[11] The answer naturally depends on the definition of "people", i.e. is only Homo sapiens to be counted, or all of genus Homo, but due to the small population sizes in the Lower Paleolithic, the order of magnitude of the estimate is not affected by the choice of cut-off date substantially more than by the uncertainty of estimates throughout the Neolithic to Iron Age.[12] The estimate is more crucially affected by the estimate of infant mortalitys vs. stillborn infants, due to the very high infant mortality throughout the pre-modern period. An estimate on the "total number of people who have ever lived" as of 1995 was calculated by Haub (1995) at "about 105 billion births since the dawn of the human race" with a cut-off date at 50,000 BC (beginning of the Upper Paleolithic), and an inclusion of a high infant mortality rate throughout pre-modern history.[13]
World population According to current projections, the global population will reach eight billion by 2024, and will likely reach around nine billion by 2042. Alternative scenarios for 2050 range from a low of 7.4 billion to a high of more than 10.6 billion.[76] Projected figures vary depending on underlying statistical assumptions and the variables used in projection calculations, especially the fertility variable. Long-range predictions to 2150 range from a population decline to 3.2 billion in the "low scenario", to "high scenarios" of 24.8 billion.[76] One extreme scenario predicted a massive increase to 256 billion by 2150, assuming the global fertility rate remained at its 1995 level of 3.04 children per woman; however, by 2010 the global fertility rate had declined to 2.52.[13][77]
