The pyramid ceases to be: in 2100 there will be 11.2 billion people in the world and there will be more elderly than ever
A study of the demography of the world population between 1950 and 2100 published by 'Our World In Data' demonstrates the radical change that our planet will experience in just 150 years.
The world population had followed a pyramid model until not long ago, but the evolution of the population is causing that model to soon cease to be valid: life expectancy is growing so much that in the coming decades the average age will exceed 41 years of age, and there will also be a record in the proportion of the elderly.
Much more older people than ever
Today, these data affirm, we are 7,700 million people on this planet. The United Nations predicts that by 2100 there will be 11.2 billion people, an increase not due to more children being born, but because people will live longer.
How much? We have been seeing the impact since the 1950s in which the study began. That year is not that far away, but then infant mortality was remarkable and amounted to 1 in 5 children. Today that mortality is from 1 to 20.
There has been a growth in the birth rate: 97 million children were born in 1950 compared to 143 million today, but it is that, as can be seen in the graph, the base of the pyramid no longer resembles what it was in 1950, and for The 2100 pyramid will actually have little of a pyramid and will be more like a box.
This new model makes clear the demographics of the world population for the beginning of the next century. the base does not widen, but it is the upper part that will be filled with all those people who live more and more and who make the proportion of people of 40, 50, 60, 70, 80 or 90 years be every growing.
That is already happening today on a global scale. For every child under 15 there were 1.8 people of working age (15 to 64 years) in 1950. Today there are 2.5 people of working age for every child under 15, and by the end of the century there will be 3, 4 people of working age. In 2100 the average age will be 41.6 years, compared to the current 30 and 23.6 years of 1950.
That population growth and especially the age of the population has really worrying consequences, not only in the area of resource production to support those 11.2 billion people, but because there will be many more retired older people who will not contribute to the market. labor.
In poor countries, this evolution could be beneficial in the productive sphere, as it has already done in current developed countries, which will be those that will have the greatest conflicts in this sphere.
