World population estimates

Estimates of world population for various points in history have been a subject of study for many years. Many authoritative sources exist for historical population estimates (e.g. U.S. Census estimates of historical world population). This article lists many of these estimates. Estimates previous to the year 10,000 BCE can be made only from archaeological evidence.

The last human point Homo sapiens hit a dangerous low, coming close to extinction, was at approximately 70,000 people during the Toba catastrophe. The University of Illinois at Urbana-Champaign estimates human world population in between 1,000 and 10,000 couples.[1][2][3]

Later bottlenecks have appeared, with important local effects, but not global to the whole world population. For example, during the Last glacial period, population across Europe decreased and people had to gather in refugia. Nevertheless, population outside Europe was mostly unaffected.[4]

Table

The following table uses astronomical year numbering for dates, negative numbers corresponding roughly to the corresponding year BCE (i.e. -10000 = 10,001 BCE, etc.). The table starts counting around the Late Glacial Maximum period, in which ice retreated and humans started to spread into the northern hemisphere.
