Population Growth
Population growth is one of the most important topics we cover at Our World in Data. For most of human history, the global population was a tiny fraction of what it is today. Over the last few centuries, the human population has gone through an extraordinary change. In 1800, there were one billion people. Today there are more than 8 billion of us.
How has world population growth changed over time?
The global population growth rate peaked long ago. The chart shows that global population growth reached a peak in 1962 and 1963 with an annual growth rate of 2.2%; but since then, world population growth has halved.4. For the last half-century we have lived in a world in which the population growth rate has been declining.
An Introduction to Population Growth
One of the most challenging applications of population growth research is to predict human population growth. The human population surpassed six billion people in 1999, and is expected reach nine ...
Major Trends in Population Growth Around the World
The world's population continues to grow, reaching 7.8 billion by mid-2020, rising from 7 billion in 2010, 6 billion in 1998, and 5 billion in 1986. The average annual growth rate was around 1.1% in 2015-2020, which steadily decreased after it peaked at 2.3% in the late 1960s.
Population growth
Population growth is the increase in the number of humans on Earth. For most of human history our population size was relatively stable. But with innovation and industrialization, energy, food, water, and medical care became more available and reliable. Consequently, global human population rapidly increased, and continues to do so, with dramatic impacts on global climate and ecosystems.
World population growth over millennia: Ancient and present phases with
Our research employs the method of temporal extrapolation to extend the study of world population growth to an unprecedentedly long period—from 1,000,000 BCE until 2100 CE—expanding the timeline far beyond the previous studies (e.g. Cohen, 1995b; Livi-Bacci, 2017; Pearson, 2015; for methastudies see Cohen, 1995a, and Van Den Bergh and ...
World population hits eight billion
According to the models of the United Nations, the world's population will reach 8 billion today — a mere 12 years since it passed 7 billion, and less than a century after the planet supported ...
Population growth
population growth, in population ecology, a change in the number of members of a certain plant or animal species in a particular location during a particular time period. Factors affecting population growth include fertility, mortality, and, in animals, migration—i.e., immigration to or emigration from a particular location. The average change in a population over time is referred to as the ...
The Outlook for Population Growth
The growth rate of the global population increased slowly from 1700 to 1950, then accelerated rapidly until the mid-1960s, peaking at just over 2% per year before descending to 1.1% per year in 2010. Between 1800 and 2011, population size increased sevenfold, coinciding with an economic expansion.
The 8 billion milestone: Risk perceptions of global population growth
In November 2022, the global human population reached 8 billion and is projected to reach 10 billion by 2060. Theories, models, and evidence indicate that global population growth (GPG) increases the likelihood of many adverse outcomes, such as biodiversity loss, climate change, mass migrations, wars, and resource shortages.
A Scientist's Warning to humanity on human population growth
Population growth generates three possible negative forces that collectively increase exponentially and eventually stop growth. These are increasing mortality rates, decreasing birth rates, and increasing rates of emigration relative to immigration. ... An example of a positive recent research finding is that restoring large grazers to depleted ...
World population growth is expected to nearly stop by 2100
For the first time in modern history, the world's population is expected to virtually stop growing by the end of this century, due in large part to falling global fertility rates, according to a Pew Research Center analysis of new data from the United Nations.. By 2100, the world's population is projected to reach approximately 10.9 billion, with annual growth of less than 0.1% - a steep ...
The Role of Population in Economic Growth
The relationship between population growth and growth of economic output has been studied extensively (Heady & Hodge, 2009).Many analysts believe that economic growth in high-income countries is likely to be relatively slow in coming years in part because population growth in these countries is predicted to slow considerably (Baker, Delong, & Krugman, 2005).

Harvard's population research center
As a Harvard University cross-school, interfaculty initiative, the Harvard Center for Population and Development Studies brings together scientists from all corners of the Harvard campus—and beyond—to make exciting advances in population research. With 8 billion people living on the planet and a projected 9.8 billion by 2050, our focus is on examining the most nuanced trends and important ...

Fig. 1. Historical growth of the world population since year 0. This will certainly not stop at the current 7 billion. According to the most recent projections by the United Nations, the number of 8 billion will probably be exceeded by 2025, and around 2045 there will be more than 9 billion people 1.
U.S. population growth has nearly flatlined, new census data shows
America's population size is standing still, according to new data from the U.S. Census Bureau. Population growth over the 12-month period from July 1, 2020 through July 1, 2021 stood at ...
World Population Problems
To appreciate the pace of population growth we should recall that world population doubled in about 1,700 years from the time of Christ until the middle of the 17th century; it doubled again in about 200 years, doubled again in less than 100, and, if the current rate of population increase were to remain constant, would double every 35 years ...
Research Guides: Human Geography: Population studies
There is long-standing debate on how population growth affects national economies. A new report from Population Matters examines the history of this debate and synthesizes current research on the topic. The authors, led by Harvard economist David Bloom, conclude that population age structure, more than size or growth per se, affects economic ...
Demographic Projections
Demographic Projections. One aspect of Pew Research Center's work is population projections, which represent our best assessment about the growth and composition of the future population, either in the U.S. or elsewhere. We've looked at how the racial and ethnic makeup of the U.S population could change over the next several decades, at ...
The Connections Between Population and Climate Change
Even in scenarios of low population growth, however, carbon-intensive economic growth and technological choices can result in high emissions [9]. Nevertheless, a growing body of research indicates that slowing global population growth through rights-based measures, such as by increasing access to voluntary family planning services, can play a ...
Main Factors Driving Population Growth
Chapter 1: Main Factors Driving Population Growth. When demographers attempt to forecast changes in the size of a population, they typically focus on four main factors: fertility rates, mortality rates (life expectancy), the initial age profile of the population (whether it is relatively old or relatively young to begin with) and migration.
Rural Resurgence: Recent Population Growth in Rural N.c
From 2010 to 2020, rural America experienced a slight population decline, contrary to decades of growth. This decline, attributed to reduced natural change and negative net migration, posed economic challenges. However, recent data indicates a shift, with rural areas experiencing growth again, largely due to increased net migration.
Human population growth and the demographic transition
Population growth is again near zero after the completion of the transition as birth and death rates both reach low levels in the most developed societies. During the intervening transition period, rapid demographic change occurs, characterized by two distinct phases. ... National Research Council 2000 Beyond six billion: forecasting the world ...

Estimating the incidence of Venezuelan migration and other
This study investigates the intricate relationship between Venezuelan migration and urban growth in Colombia from 2018 to 2021. The study employs remote sensing data and social network metrics to uncover migration patterns and their impact on urban expansion. The methodology consists of three stages. Firstly, nighttime satellite imagery is used to analyze year-over-year urban growth in Colombia.
