World population

In demographics, the world population is the total number of humans currently living, and was estimated to have reached 7.7 billion people as of April 2019. It took over 200.000 years of human history for the worlds population to reach 1 billion, and only 200 years more to reach 7 billion. The world population has experienced continuous growth following the Great Famine of 1315–1317 and the end of the Black Death in 1350, when it was near 370 million. The highest global population growth rates, with increases of over 1.8% per year, occurred between 1955 and 1975 - peaking to 2.1% between 1 ...

World population estimates

This article lists current estimates of world population, as well as projections of population growth. In summary, estimates for the progression of world population since the late medieval period are in the following ranges: Estimates for pre-modern times are necessarily fraught with great uncertainties, and few of the published estimates have confidence intervals; in the absence of a straightforward means to assess the error of such estimates, a rough idea of expert consensus can be gained by comparing the values given in independent publications. Population estimates cannot be considered ...

                                               

Human overpopulation

Human overpopulation is when there are too many people for the environment to sustain. In more scientific terms, there is overshoot when the ecological footprint of a human population in a geographical area exceeds that places carrying capacity, damaging the environment faster than it can be repaired by nature, potentially leading to an ecological and societal collapse. Overpopulation could apply to the population of a specific region, or to world population as a whole. Overpopulation can result from an increase in births, a decline in mortality rates, an increase in immigration, or an uns ...

                                               

World population milestones

World population milestones were unnoticed until the 20th century, since there were no reliable data on global population dynamics. It is estimated that the population of the world reached one billion for the first time in 1804. It would be another 123 years before it reached two billion in 1927, but it took only 33 years to rise by another billion people, reaching three billion in 1960. Thereafter, the global population reached four billion in 1974, five billion in 1987, six billion in 1999 and, by some estimates, seven billion in October 2011 with other estimates being in March 2012. It ...
