In world demographics, the world population is the total number of humans currently alive
It took around 300,000 years of human prehistory and history for the human population to reach a billion and only 218 more years to reach 8 billion.
World population milestones went unnoticed until the 20th century, since there was no reliable data on global population dynamics [2] the population of the world reached [3][4] 1 billion in 1804 2 billion in 1928 3 billion in 1961 4 billion in 1975 5 billion in 1988 6 billion in 1999 7 billion in 2011 8 billion in 2022 old estimates put the global population at 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. The percentage shares of china, india and rest of south asia of the world population have remained at similar levels for the last few thousand years of recorded history
[1][2] the world's population is predominantly urban and suburban, [3] and there has been significant migration toward cities and urban centers.
Chart created by our world in data in 2024 This article contains a list of countries by past and projected future population. These sources like youtube are extremely unreliable sources Whoever made those youtube videos most likely has the un/uscb sources.] this is a list of population milestones by country (and year first reached)
Only existing countries are included, not former countries.
