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 national 1 July, mid-year population estimates (usually based on past national censuses) supplied in these tables are given in thousands. The retrospective figures use the present-day names and world political division: for example, the table gives data for each of the 15 republics of the former Soviet Union, as if they had already been independent in 1950.
The UN Population Division report of 2022 projects world population to continue growing after 2050, although at a steadily decreasing rate, to peak at 10.4 billion in 2086, and then to start a slow decline to about 10.3 billion in 2100 with a growth rate at that time of -0.1%.
Globally, the rate of population growth has declined from a peak of 2.2% per year in 1963. [9] Population growth alongside increased consumption is a driver of environmental concerns, such as biodiversity loss and climate change, [10] [11] due to overexploitation of natural resources for human development.

The table starts counting approximately 10,000 years before present, or around 8,000 BC, during the middle Greenlandian, about 1,700 years after the end of the Younger Dryas and 1,800 years before the 8.2-kiloyear event. From the beginning of the early modern period until the 20th century, world population has been characterized by a rapid growth.
Growth rate of world population (1950–2010) The sharp decline in world population growth in the early 1960s caused primarily by the Great Chinese Famine. Globally, the growth rate of the human population has been declining since peaking in 1962 and 1963 at 2.20% per annum. In 2009, the estimated annual growth rate was 1.1%. [82]
A chart of changes in world population growth rate from 1950–2010 (red) and predicted changes in world population growth rate from 2010–2050 (blue). The original was created 6 Dec 2003 by Securiger from data provided by the U.S. Census Bureau. Converted to SVG by Conscious.
World population pyramid from 1950 to projected in 2100 (UN, World Population Prospects 2017) A population pyramid (age structure diagram) or "age-sex pyramid" is a graphical illustration of the distribution of a population (typically that of a country or region of the world) by age groups and sex; it typically takes the shape of a pyramid when the population is growing.
