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.
Published estimates for the 1st century (" AD 1 ") suggest uncertainty of the order of 50% (estimates range between 150 and 330 million). Some estimates extend their timeline into deep prehistory, to " 10,000 BC", i.e., the early Holocene, when world population estimates range roughly between 1 and 10 million (with an uncertainty of up to an ...
Estimate numbers are from the beginning of the year and exact population figures are for countries that held a census on various dates in the 1700s. The bulk of these numbers are sourced from Alexander V. Avakov's Two Thousand Years of Economic Statistics, Volume 1 , pages 18 to 20, which cover population figures from the year 1700 divided into ...

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]
