Thus, the figures after the 1960 column show the percentage annual growth for the 1955-60 period; the figures after the 1980 column calculate the same value for 1975–80; and so on. The formulas used for the annual growth rates are the standard ones, used both by the United Nations Statistics Division and by National Census Offices worldwide.
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.
The population of the More Developed regions is slated to remain mostly unchanged, at 1.2-1.3 billion for the remainder of the 21st century. All population growth comes from the Less Developed regions. [6] [7] The table below breaks out the UN's future population growth predictions by region [6] [7]

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.
Population growth is the increase in the number of people in a population or dispersed group. The global population has grown from 1 billion in 1800 to 8.2 billion in 2025. [ 3 ] Actual global human population growth amounts to around 70 million annually, or 0.85% per year.
Column four is from the UN Population Division [3] and shows a projection for the average natural increase rate for the time period shown using the medium fertility variant. Blank cells in column four indicate lack of data. Note: Rates below are per 1000 population. Location links are Demographics of LOCATION links.
