Population of the world from 10,000 BC to 2000 AD (logarithmic scale) Estimating the ancestral population of anatomically modern humans, Colin McEvedy and Richard Jones chose bounds based on gorilla and chimpanzee population densities of 1/km 2 and 3-4/km 2, [1] respectively, then assumed that as Homo erectus moved up the food chain, they lost an order of magnitude in density.
For 1790 through 1990, tables are taken from the U.S Census Bureau's "Population of the 100 Largest Cities and Other Urban Places in the United States: 1790 to 1990."
