when will the world population hit 8 billion?
2024
according to current projections, the global population will reach eight billion by 2024, and is likely to 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. 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. 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.
world population
according to papers published by the united states census bureau, the world population hit 6.5 billion on 24 february 2006. the united nations population fund designated 12 october 1999 as the approximate day on which world population reached 6 billion. this was about 12 years after world population reached 5 billion in 1987, and six years after world population reached 5.5 billion in 1993. the population of countries such as nigeria is not even known to the nearest million, so there is a considerable margin of error in such estimates.
