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.
The world population increased from 1 billion in 1800 to around 8 billion today.
The world population growth rate declined from around 2% per year 50 years ago to under 1.0% per year.
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.
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. The cartogram shows where in the world the global population was at home in 2018.
The cartogram is made up of squares, each of which represents half a million people of a country’s population. 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.
As 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. 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).
Which countries are most densely populated?
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.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.
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.
The developing countries are most affected areas by incessant growth in population.
These countries are going to suffer more due to over population as it causes economic and food problem. Over population is a major cause of food shortage and malnutrition because more people need more food.
Due to over population, water resources are under great stress because more people consume more water.
The effect of depletion of fossil energy is that the fuel prices are rising everywhere. Moreover, energy production is reduced.
We can ensure food and resources for future generation by doing things like we should manage and protect nature resources and control population growth and strict measures on usage of natural resources.
