Data describing the growth of the world population in the past 12,000 yearsare analysed. It is shown that, if unchecked, population does not increaseexponentially but hyperbolically. This analysis reveals threeapproximately-determined episodes of hyperbolic growth: 10,000-500 BC, AD500-1200 and AD 1400-1950, representing a total of about 89% of the past 12,000years. It also reveals three demographic transitions: 500 BC-AD 500, AD1200-1400 and AD 1950-present, representing the remaining 11% of the past12,000 years. The first two transitions were between sustained hyperbolictrajectories. The current transition is to an unknown trajectory. There wasnever any form of dramatic transition from stagnation to growth, describedoften as a takeoff, because there was no stagnation in the growth of the worldpopulation. Correct understanding of the historical growth of human populationis essential in the correct interpretation of the historical growth of incomeper capita.
