As with any type of projection, there is a degree of uncertainty surrounding these latest population projections. These figures are based on the medium projection variant, which assumes a decline of fertility for countries where large families are still prevalent, as well as a slight increase of fertility in several countries with fewer than two children per woman on average.
Survival prospects are also projected to improve in all countries. More than half of global population growth between now and is expected to occur in Africa. Africa has the highest rate of population growth among major areas. The population of sub-Saharan Africa is projected to double by A rapid population increase in Africa is anticipated even if there is a substantial reduction of fertility levels in the near future.
In sharp contrast, the populations of 55 countries or areas in the world are expected to decrease by , of which 26 may see a reduction of at least ten per cent.
Several countries are expected to see their populations decline by more than 15 per cent by , including Bosnia and Herzegovina, Bulgaria, Croatia, Hungary, Japan, Latvia, Lithuania, Republic of Moldova, Romania, Serbia, and Ukraine.
Fertility in all European countries is now below the level required for full replacement of the population in the long run around 2. Future population growth is highly dependent on the path that future fertility will take. According to the World Population Prospects Revision , global fertility is projected to fall from 2. Overall, significant gains in life expectancy have been achieved in recent years. Globally, life expectancy at birth is expected to rise from Please contact us to get started with full access to dossiers, forecasts, studies and international data.

The global population Today, the global population amounts to around 7 billion people, i. More than half of the global population is living in Asia, while one quarter of the global population resides in Africa. High fertility rates in Africa and Asia, a decline in the mortality rates and an increase in the median age of the world population all contribute to the global population growth.
Statistics show that the global population is subject to increase by almost 4 billion people by The global population growth is a direct result of people living longer because of better living conditions and a healthier nutrition.
Three out of five of the most populous countries in the world are located in Asia. Ultimately the highest population growth rate is also found there, the country with the highest population growth rate is Lebanon. This could be due to a low infant mortality rate in Lebanon or the ever -expanding tourism sector.
More importantly, Lebanon is also the country with the highest net migration rate in the world. Loading statistic Show source.

Supplementary notes. Life expectancy — Improving health leads to falling mortality and is therefore the factor that increases the size of the population. Life expectancy, which measures the age of death, has doubled in every region in the world as we show here.
Fertility rates — Rapid population growth has been a temporary phenomenon in many countries. It comes to an end when the average number of births per woman — the fertility rate — declines.
In the article we show the data and explain why fertility rates declined. Age Structure — What is the age profile of populations around the world? How did it change and what will the age structure of populations look like in the future? One way to understand the distribution of people across the world is to reform the world map, not based on area but according to population.
This is shown here in a population cartogram : a geographical presentation of the world where the size of the countries are not drawn according to the distribution of land, but according to the distribution of people. The cartogram shows where in the world the global population was at home in The Small countries with a high population density increase in size in this cartogram relative to the world maps we are used to — look at Bangladesh, Taiwan, or the Netherlands.
Large countries with a small population shrink in size look for Canada, Mongolia, Australia, or Russia. Our understanding of the world is often shaped by geographical maps. But this tells us nothing about where in the world people live. To understand this, we need to look at population density.
Globally the average population density is 25 people per km 2 , but there are very large differences across countries. If we want to understand how people are distributed across the world, another useful tool is the population cartogram : a geographical presentation of the world where the size of the countries are not drawn according to the distribution of land, but according to the distribution of people. Here we show how the world looks in this way.
When we see a standard map we tend to focus on the largest countries by area. But these are not always where the greatest number of people live. The chart shows the increasing number of people living on our planet over the last 12, years. A mind-boggling change: The world population today that is 1,times the size of what it was 12 millennia ago when the world population was around 4 million — half of the current population of London.
What is striking about this chart is of course that almost all of this growth happened just very recently. Historical demographers estimate that around the year the world population was only around 1 billion people.
This implies that on average the population grew very slowly over this long time from 10, BCE to by 0. After this changed fundamentally: The world population was around 1 billion in the year and increased 7-fold since then. Around billion people have ever lived on our planet. For the long period from the appearance of modern Homo sapiens up to the starting point of this chart in 10, BCE it is estimated that the total world population was often well under one million.
In this period our species was often seriously threatened by extinction. The interactive visualization is here. And you can also download the annual world population data produced by Our World in Data. A number of researchers have published estimates for the total world population over the long run, we have brought these estimates together and you can explore these various sources here.
In terms of recent developments, the data from the UN Population Division provides consistent and comparable estimates and projections within and across countries and time, over the last century. This data starts from estimates for , and is updated periodically to reflect changes in fertility, mortality and international migration. In the section above we looked at the absolute change in the global population over time.
But what about the rate of population growth? The global population growth rate peaked long ago. The chart shows that global population growth reached a peak in and with an annual growth rate of 2.
For the last half-century we have lived in a world in which the population growth rate has been declining. The UN projects that this decline will continue in the coming decades. The answer is no. For population growth to be exponential, the growth rate would have be the same over time e.
In absolute terms, this would result in an exponential increase in the number of people. But, as we see in this chart, since the s the growth rate has been falling. This means the world population is not growing exponentially — for decades now, growth has been more similar to a linear trend. The previous section looked at the growth rate. This visualization here shows the annual global population increase from to today and the projection until the end of this century.
The absolute increase of the population per year has peaked in the late s at over 90 million additional people each year. But it stayed high until recently. From now on the UN expects the annual increase to decline by around 1 million every year. There are other ways of visually representing the change in rate of world population growth. Two examples of this are shown in the charts below. The visualization shows how strongly the growth rate of the world population changed over time. In the past the population grew slowly: it took nearly seven centuries for the population to double from 0.
As the growth rate slowly climbed, the population doubling time fell but remained in the order of centuries into the first half of the 20th century.
Things sped up considerably in the middle of the 20th century. The fastest doubling of the world population happened between and a doubling from 2. This period was marked by a peak population growth of 2. Since then, population growth has been slowing, and along with it the doubling time. In this visualisation we have used the UN projections to show how the doubling time is projected to change until the end of this century.
By , it will once again have taken approximately years for the population to double to a predicted This visualization provides an additional perspective on population growth: the number of years it took to add one billion to the global population. This visualisation shows again how the population growth rate has changed dramatically through time.
By the third billion, this period had reduced to 33 years, reduced further to 15 years to reach four. The period of fastest growth occurred through to , taking only 12 years to increase by one billion for the 5th, 6th and 7th. The world has now surpassed this peak rate of growth, and the period between each billion is expected to continue to rise.
Two hundred years ago the world population was just over one billion. Since then the number of people on the planet grew more than 7-fold to 7. How is the world population distributed across regions and how did it change over this period of rapid global growth?
In this visualization we see historical population estimates by region from through to today. If you want to see the relative distribution across the world regions in more detail you can switch to the relative view. The world region that saw the fastest population growth over last two centuries was North America. The population grew fold. Latin America saw the second largest increase fold. Over the same period the population Europe of increased 3-fold, in Africa fold, and in Asia 6-fold.
The distribution of the world population is expected to change significantly over the 21st century. We discuss projections of population by region here. Over the last century, the world has seen rapid population growth. But how are populations distributed across the world? Which countries have the most people?
In the map, we see the estimated population of each country today. By clicking on any country, you can also see how its population has evolved over this period. You can learn more about future population growth by country here.
This series of maps shows the distribution of the world population over time. The first map — in the top-left corner — shows the world population in BC. Global population growth peaked in the early s. But how has population growth varied across the world? Migration flows are not counted. Both of these measures of population growth across the world are shown in the two charts.
You can use the slider underneath each map to look at this change since Clicking on any country will show a line chart of its change over time, with UN projections through to We see that there are some countries today where the natural population growth not including migration is slightly negative: the number of deaths exceed the number of births. When we move the time slider underneath the map to past years, we see that this is a new phenomenon.
Up until the s, there were no countries with a negative natural population growth. Worldwide, population growth is slowing—you can press the play arrow at the bottom of the chart to see the change over time. Overall, growth rates in most countries have been going down since the s. Yet substantial differences exist across countries and regions. Moreover, in many cases there has been divergence in growth rates. One of the big lessons from the demographic history of countries is that population explosions are temporary.
For many countries the demographic transition has already ended, and as the global fertility rate has now halved we know that the world as a whole is approaching the end of rapid population growth. This visualization presents this big overview of the global demographic transition — with the very latest data from the UN Population Division.
As we explore at the beginning of the entry on population growth , the global population grew only very slowly up to — only 0. In the many millennia up to that point in history very high mortality of children counteracted high fertility. The world was in the first stage of the demographic transition.
Once health improved and mortality declined things changed quickly. Particularly over the course of the 20th century: Over the last years global population more than quadrupled. As we see in the chart, the rise of the global population got steeper and steeper and you have just lived through the steepest increase of that curve. This also means that your existence is a tiny part of the reason why that curve is so steep.
To provide space, food, and resources for a large world population in a way that is sustainable into the distant future is without question one of the large, serious challenges for our generation. We should not make the mistake of underestimating the task ahead of us. Yes, I expect new generations to contribute , but for now it is upon us to provide for them. Population growth is still fast: Every year million are born and 58 million die — the difference is the number of people that we add to the world population in a year: 82 million.
In red you see the annual population growth rate that is, the percentage change in population per year of the global population. It peaked around half a century ago.
Peak population growth was reached in with an annual growth of 2. This slowdown of population growth was not only predictable, but predicted.
