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.
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.

European population reached a peak growth rate of 10 per thousand per year in the second half of the 19th century. During the 20th century, the growth rate among the European populations fell and was overtaken by a rapid acceleration in the growth rate in other continents, which reached 21 per thousand per year in the last 50 years of the ...
Projections of population growth. 1. World population growth 1700–2100, 2022 projection. Projections of population growth are attempts to show how the human population statistics might change in the future. [1] These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. [2]
Population growth is the increase in the number of people in a population or dispersed group. Actual global human population growth amounts to around 83 million annually, or 1.1% per year. [2] The global population has grown from 1 billion in 1800 to 8.1 billion in 2024. [3] The UN projected population to keep growing, and estimates have put ...
Historical demography. Historical demography is the quantitative study of human population in the past. It is concerned with population size, with the three basic components of population change (fertility, mortality, and migration), and with population characteristics related to those components, such as marriage, socioeconomic status, and the ...
While in 10,000 BC, the world population stood at 2 million, it rose to 45 million by 3000 BC. By the Iron Age in 1000 BC, the population had risen to 72 million. By the end of the ancient period in AD 500, the world population is thought to have stood at 209 million. In 10,500 years, the world population increased by 100 times. [2]
