World population more than doubled over the course of the millennium, from about an estimated 50–100 million to an estimated 170–300 million.Close to 90% of world population at the end of the first millennium BC lived in the Iron Age civilizations of the Old World (Roman Empire,Parthian Empire,Graeco-Indo-Scythian andHindu kingdoms,Han China). The population of the Americas was below 20 million, concentrated inMesoamerica (Epi-Olmec culture);that ofSub-Saharan Africa was likely below 10 million. The population of Oceania was likely less than one million people.[2]

(2011) estimate 188 million as of AD 1, citing a literature range of 170 million (low) to 300 million (high).Out of the estimated 188M, 116M are estimated for Asia (East, South/Southeast and Central Asia, excluding Western Asia),44M for Europe and the Near East, 15M for Africa (including Egypt and Roman North Africa), 12M for Mesoamerica and South America. North America and Oceania were at or below one million.Jean-Noël Biraben, "Essai sur l'évolution du nombre des hommes",Population 34-1 (1979), 13–25 (p. 22) estimates c. 100 million at 1200 BC and c. 250 million at AD 1.[1]
