UN estimates (as of 2017) for world population by continent in 2000 and in 2050 (pie chart size to scale) Asia Africa Europe Central/South America North America Oceania. Population estimates for world regions based on Maddison (2007), [30] in millions. The row showing total world population includes the average growth rate per year over the ...
The current world population growth is approximately 1.09%. [7] People under 15 years of age made up over a quarter of the world population (25.18%), and people age 65 and over made up nearly ten percent (9.69%) in 2021. [7] The world population more than tripled during the 20th century from about 1.65 billion in 1900 to 5.97 billion in 1999.
Estimates of world population by their nature are an aspect of modernity, possible only since the Age of Discovery.Early estimates for the population of the world [10] date to the 17th century: William Petty, in 1682, estimated the world population at 320 million (current estimates ranging close to twice this number); by the late 18th century, estimates ranged close to one billion (consistent ...
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 ...
The 2022 projections from the United Nations Population Division (chart #1) show that annual world population growth peaked at 2.3% per year in 1963, has since dropped to 0.9% in 2023, equivalent to about 74 million people each year, and could drop even further to minus 0.1% or rise to between 1 to 2.5% or higher by 2100.

March 27, 2023 at 11:33 PM. The global population could peak to an all-time high just below nine billion people in 2050 and then start falling, a new analysis suggests. Researchers from the ...
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 table below shows annual population growth rate history and projections for various areas, countries, regions and sub-regions from various sources for various time periods. The right-most column shows a projection for the time period shown using the medium fertility variant. Preceding columns show actual history.
