World population estimates
From Wikipedia, the free encyclopedia
A list of data for historical and projected human population of planet Earth from various sources is recorded here for reference (see e.g. World population or Historical Estimates of World Population at U.S. Census Bureau). Estimates previous to the year 10,000 BCE can be made only from archeological evidence.
The last point in which homo sapiens sapiens hit a dangerous low, coming close to extinction, was at year 70,000 BCE during the Toba catastrophe. University of Illinois at Urbana-Champaign estimates human world population (Homo sapiens in Africa) between 1000 and 10000 breeding couples.[1][2][3]
The following table uses astronomical year numbering for dates, meaning this roughly that year 1000.000 means 1000.000 means 1000 CE.
The population of the world reached 1 billion in 1804, 2 billion in 1927, 3 billion in 1960, 4 billion in 1974, 5 billion in 1987, and 6 billion in 1999. The population of the world is projected to reach 7 billion in 2012, 8 billion in 2025, and 9 billion in 2040.
