As of 2022, an estimated total of almost 110 billion humans have died, or roughly 94% of all humans to have ever lived. [9] A substudy of gerontology known as biogerontology seeks to eliminate death by natural aging in humans, often through the application of natural processes found in certain organisms. [10]

Nuclear war is an often-predicted cause of the extinction of humankind. [1]Human extinction or omnicide is the hypothetical end of the human species, either by population decline due to extraneous natural causes, such as an asteroid impact or large-scale volcanism, or via anthropogenic destruction (self-extinction), for example by sub-replacement fertility.
An unnatural cause of death results from an external cause, typically including homicides, suicides, accidents, medical errors, alcohol intoxications and drug overdoses. [6] [7] Jurisdictions differ in how they categorize and report unnatural deaths, including level of detail and whether they are considered a single category with subcategories, or separate top-level categories.
In 2018 researchers suggested an alternative model in which "the disease was spread from human fleas and body lice to other people". The second model claims to better fit the trends of the plague's death toll, as the rat-flea-human hypothesis would have produced a delayed but very high spike in deaths, contradicting historical death data.

One of his main findings was that democracies have much less democide than authoritarian regimes. [2] Rummel argued that there is a relation between political power and democide.
