In world demographics, the world population is the total number of humans currently alive. It was estimated by the United Nations to have exceeded eight billion in mid-November 2022. It took around 300,000 years of human prehistory and history for the human population to reach a billion and only 218 years more to reach 8 billion.
In 1800, the population of Nigeria was 12.1 million, and 2.9% of that rounds to 349,081. ^ Today, the Ankole population is estimated to make up 9.8% of the Ugandan population. In 1800, the population of Uganda was 2.1 million, and 9.8% of that is 205,800. ^ Hawaii adopted the British Red Ensign as an independent nation from 1793 to 1800.

The right-most column shows a projection for the time period shown using the medium fertility variant. Preceding columns show actual history.
1790. When the United States declared independence in 1776, Philadelphia was its most populous city. By the time the first U.S. census count was completed in 1790, New York City had already grown to be 14% more populous than Philadelphia (though Philadelphia still had the larger metropolitan population in 1790).
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.
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 ...
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 .
