Own work, data from 3rd table in World Population - Population Figures as presented together with data from US Census Historical EstimatesĬlick on a date/time to view the file as it appeared at that time. Therefore, effort has been put into creating historical trends of various. Population grew at a faster rate from about 1700AD onwards, which coincided with the start of the Industrial Revolution There was then a sharp increase from the beginning of the 20th century followed by a very dramatic acceleration in population growth from the middle of the 20th century (around 1950) onwards.Īt over 6.7 billion (see US Census data) the World Population is approximately 3 times higher in 2009 than it was at approximately 2.3 billion or less (historic census) in 1939, despite the appalling loss of life in World War II (an upper estimate of which is some 72 million). Incredibly, each new billion people has come faster than the previousit was roughly only a decade ago that we crossed the 7 billion threshold. By the end of 2022 or within the first months of 2023, that number is expected to officially cross the 8 billion mark. Please see notes regarding the source data and method used for plotting the resulting population dips caused by both the Black Death and later plagues LinkedIn Today, the global population is estimated to sit at 7.91 billion people. Calculating the number of people who have ever lived is part science and part art. We first made this estimate in 1995 and have updated it periodically since then.

It can clearly be seen that the total world population was steadily rising during the period 1000AD to around 1700AD, though with major disruption from outbreaks of plague (most notably the Black Death from 1350 AD - 1400 AD).
