20s

The 20s decade ran from January 1, AD 20, to December 31, AD 29.

In Europe, the 20s saw revolts by the

Daeso

.

In science, the 20s saw the manufacture of

Jewish sect in Jerusalem. Geographica, an encyclopedia of geographical knowledge created by Strabo

, was finished no later than AD 23.

Manning (2008) tentatively estimates the world population in AD 20 as 246 million.

Demographics

Due to lack of reliable demographic data, estimates of the world population in the 1st century vary wildly, with estimates for AD 1 varying from 150^[1] to 300^[2] million. Demographers typically do not attempt to estimate most specific years in antiquity, instead giving approximate numbers for round years such as AD 1 or AD 200. However, attempts at reconstructing the world population in more specific years have been made, with Manning (2008) tentatively estimating the world population in AD 20 as 246 million.^[3]
