The map shows the number of people per square kilometer (km 2) across the world. It is calculated by dividing the total population of an area by its total land area. Population density is a measure of how densely populated an area is.

To understand this, we need to look at population density. But this tells us nothing about where in the world people live. Geographical maps often shape our understanding of the world. You can find more details on this cartogram in our explainer: ‘ The map we need if we want to think about how global living conditions are changing‘. Large countries with a small population shrink in size (look for Canada, Mongolia, Australia, or Russia). 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. The 11.5 million Belgians are represented by 23 squares the 49.5 million Colombians are represented by 99 squares the 1.415 billion people in China are represented by 2830 squares, and the entire world population of 7.633 billion people in 2018 is represented by the total sum of 15,266 squares.Īs the size of the population rather than the size of the territory is shown in this map you can see some big differences when you compare it to the standard geographical map we’re most familiar with. The cartogram is made up of squares, each of which represents half a million people of a country’s population. The cartogram shows where in the world the global population was at home in 2018. This is shown here in a population cartogram: a geographical presentation of the world where the size of the countries is not drawn according to the distribution of land, but according to the distribution of people. One way to understand the distribution of people across the world is to reform the world map, not based on the area but according to population.

In the article we show the data and explain why fertility rates declined.Īge 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? It comes to an end when the average number of births per woman – the fertility rate – declines. Life expectancy, which measures the age of death, has doubled in every region in the world as we show here.Ĭhild & infant mortality – Mortality at a young age has a particularly big impact on demographic change.įertility rates – Rapid population growth has been a temporary phenomenon in many countries. Life expectancy – Improving health leads to falling mortality and is, therefore, the factor that increases the size of the population.

We explain how we know that population growth is coming to an end, and present projections of the drivers of population growth. The world population growth rate declined from around 2% per year 50 years ago to under 1.0% per year.įuture population growth – This article focuses on the future of population growth. The world population increased from 1 billion in 1800 to around 8 billion today. When and why did the world population grow? And how does rapid population growth come to an end? These are the big questions that are central to this research article.
