Chart created by Our World In Data in 2024. The UN Population Division has calculated the future population of the world's countries, based on current demographic trends.

It is also a natural biological phenomenon: The world’s population has tripled in the last 70 years—and will settle into a new dynamic equilibrium as limitations are reached, with an expected ...
The report — released on World Population Day — says the global population is then expected to decline to around 10.2 billion by the end of the century. John Wilmoth, head of the U.N ...
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 ...
Graph of world population over the past 12,000 years . As a general rule, the confidence of estimates on historical world population decreases for the more distant past. Robust population data exist only for the last two or three centuries. Until the late 18th century, few governments had ever performed an accurate census.
