Published estimates for the 1st century ("AD 1") suggest uncertainty of the order of 50% (estimates range between 150 and 330 million). Some estimates extend their timeline into deep prehistory, to " 10,000 BC", i.e., the early Holocene , when world population estimates range roughly between 1 and 10 million (with an uncertainty of up to an ...

1000 million Mark Notgeld banknote (1923) of Frankfurt am Main. According to the Oxford English Dictionary, the word billion was formed in the 16th century (from million and the prefix bi-, "two"), meaning the second power of a million (1,000,000 2 = 10 12). This long scale definition was similarly applied to trillion, quadrillion and so on ...

Java, an island in Indonesia, had about 5 million inhabitants in 1815; it had a population of over 139 million in 2020. [54] In just one hundred years, the population of Brazil decupled (x10), from about 17 million in 1900, or about 1% of the world population in that year, to about 176 million in 2000, or almost 3% of the global population in ...
[1] [2] Since the customary, traditional (non-technical) decimal format of large numbers can be lengthy, other systems have been devised that allows for shorter representation. For example, a billion is represented as 13 characters (1,000,000,000) in traditional decimal format, but is only 3 characters (10 9) when expressed in exponential format.
The Day of Five Billion, 11 July 1987, was designated by the United Nations Population Fund as the approximate day on which the world population reached five billion. Matej Gašpar from Zagreb , Croatia (then SR Croatia , SFR Yugoslavia ), was chosen as the symbolic 5-billionth person alive on Earth .
1.3 billion Eukaryotic life dies out on Earth due to carbon dioxide starvation. Only prokaryotes remain. [81] 1.5 billion Callisto is captured into the mean-motion resonance of the other Galilean moons of Jupiter, completing the 1:2:4:8 chain. (Currently only Io, Europa and Ganymede participate in the 1:2:4 resonance.) [91] 1.5–1.6 billion
