The table starts counting approximately 10,000 years before present, or around 8,000 BC, during the middle Greenlandian, about 1,700 years after the end of the Younger Dryas and 1,800 years before the 8.2-kiloyear event. From the beginning of the early modern period until the 20th century, world population has been characterized by a rapid growth.
Demographic history is the reconstructed record of human population in the past. Given the lack of population records prior to the 1950s, there are many gaps in our record of demographic history. Historical demographers must make do with estimates, models and extrapolations. For the demographic methodology, see historical demography.
Huff et al. (2010) rejected all models with an ancient effective population size larger than 26,000. [9] For ca. 130,000 years ago, Sjödin et al. (2012) estimate an effective population size of the order of 10,000 to 30,000 individuals, and infer an actual "census population" of early Homo sapiens of roughly 100,000 to 300,000 individuals.

Map of the world in 323 BC Map of the Eastern Hemisphere in 100 BC. Classical demography refers to the study of human demography in the Classical period.It often focuses on the absolute number of people who were alive in civilizations around the Mediterranean Sea between the Bronze Age and the fall of the Western Roman Empire, but in recent decades historians have been more interested in ...
Life expectancy at birth in the Roman Empire is estimated at about 22–33 years. [9] [notes 1] For the two-thirds to three-quarters of the population surviving the first year of life, [10] life expectancy at age 1 is estimated at around 34–41 remaining years (i.e. expected to live to age 35–42), while for the 55–65% surviving to age 5, life expectancy was around 40–45. [11]
Teotihuacan was a large pre-historic city that underwent massive population growth and sustained it over most of the city's occupancy. In 100 CE, the population could be estimated at around 60,000-80,000, after 200 years of the city's occupancy, within 20 km 2 of the city. The population, eventually, stabilized around 100,000 people around 300 ...
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 1 721 425.5 – 2 086 667.5 [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]
World population growth relaxed after the burst that came about from the Neolithic Revolution. World population was largely stable in this time at roughly 50 million, growing at an average of 0.027% per year.
