The first millennium of the anno Domini or Common Era was a millennium spanning the years 1 to 1000 (1st to 10th centuries; in astronomy: JD 1721425.5 – 2086667.5[1]). The world population rose more slowly than during the preceding millennium, from about 200 million in the year 1 to about 300 million in the year 1000.[2]
In Mesoamerica, the first millennium was a period of enormous growth known as the Classic Era (200–900). Teotihuacan grew into a metropolis and its empire dominated Mesoamerica. In South America, pre-Incan, coastalcultures flourished, producing impressive metalwork and some of the finest pottery seen in the ancient world.
In North America, the Mississippian culture rose at the end of the millennium in the Mississippi and Ohio river valleys. Numerous cities were built; Cahokia, the largest, was based in present-day Illinois. The construction of Monks Mound at Cahokia was begun in 900–950.

Goldewijk et al. (2011) estimate 188 million as of the year 1, citing a literature range of 170 million (low) to 300 million (high).
Out of the estimated 188 million, 116 million are estimated for Asia (East Asia, South Asia, Southeast Asia, and Central Asia, excluding Western Asia),
44 million for Europe and the Near East, 15 million for Africa (including Roman Egypt and Roman North Africa), 12 million for Mesoamerica and South America. North America and Oceania were at or below one million.
For 1000, they estimate the world population at 295 million.
