And these two tables should be taken with an extra-large dose of salt, as Timescape (1983) is getting rather old. I include them so you can do rough (say factor of 2) calculation.

Population: Summary Timetable [Timescale, p269]
population growing: c. 9500 yr. From ?8 million to peak, [...]|
level or falling populations: c. 2000 yr. In the Old World, associated with the increase in disease, and poorly defined crashes, esp. after 1838 yr (AD 162, Eurasian epidemics); populations were still rising in the Americas.
population surge: c. 1000 yr (AD 1000). In China and Europe.
population crash: c. 790 yr (AD 1290). Dated by Chinese census, probably typical of Eurasia.
population recovery: c. 650 yr (AD 1450). Dated for the estimate for China, again perhaps typical of Eurasia.
Amerindian epidemics (population crash): 479 yr (AD 1521). A direct consequence of the breakout of the European navigators and their diseases. [...?]
population boom: c. 300 yr (AD 1700). First in China (interrupted 1850, resumed 1950); in Europe from c. AD 1800.
global population boom: c. AD 1930
population inflection: c. AD 1970. The rate of growth abating in the world as a whole (c. 1900 in Europe).
