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 7.9 billion in 2020. [3] The UN projected population to keep growing, and estimates have put ...
Methodology. 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 highest global population growth rates, with increases of over 1.8% per year, occurred between 1955 and 1975, peaking at 2.1% between 1965 and 1970. The growth rate declined to 1.1% between 2015 and 2020 and is projected to decline further in the 21st century.
Although the rate of growth decreases, population continues to rise. In 2050 still growing by over 45 million per year Map of countries and territories by fertility rate as of 2020 Sustainable population. Many studies have tried to estimate the world's sustainable population for humans, that is, the maximum population the world can host.
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%.
The COVID-19 pandemic has accelerated this trend, resulting in a historically slow population increase in 2021. The growth rate is 0.1% as estimated for 2021. The birth rate is 11.0 births/1,000 population, as of 2020. This was the lowest birth rate since records began.
Historically, human population control has been implemented with the goal of limiting the rate of population growth. In the period from the 1950s to the 1980s, concerns about global population growth and its effects on poverty, environmental degradation, and political stability led to efforts to reduce population growth rates. While population ...
China is the second most populous country in Asia as well as the second most populous country in the world, with a population of approximately 1.4 billion. China has an enormous population with a relatively small youth component, partially a result of China's one-child policy that was implemented from 1979 until 2015.
