[ 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 .
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.
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.
Emigration to the New England colonies after 1640 and the start of the English Civil War decreased to less than 1% (about equal to the death rate) in nearly all years before 1845. The rapid growth of the New England colonies (total population ≈700,000 by 1790) was almost entirely due to the high birth rate (>3%) and low death rate (<1%) per year.
For 1790 through 1990, tables are taken from the U.S Census Bureau's "Population of the 100 Largest Cities and Other Urban Places in the United States: 1790 to 1990." [1] For year 2000 rankings, data from the Census Bureau's tally of "Cities with 100,000 or More Population Ranked by Selected Subject" is used. [2]
