World Population Shifts, 1950 to 2050

The World Bank Dataviz blog (through the Economist) has produced yet another prediction graphic that has immediately become one of my favorites-

At the top is a percentage change forecast of population from present day up until 2050 by world region. Africa’s population change is spiking with its high fertility rates and decreasing child mortality rates, surpassing Asia with the population giants of India and China in rate of change. Europe, by this time, is expected to see negative population growth, as some northern European nations are already experiencing.

“The world in 1950 looked very different from how it does now. Europe was home to 22% of the world’s 2.5 billion people. Germany, Britain, Italy and France all counted among the 12 most populous countries. But strong economic growth in Asia coupled with high fertility rates in Africa have contributed to a big regional shift in the global population.”

Below the rate of change graph is a remarkable chart of the most populous nation within the 50 year intervals, color-coded by region. As would be assumed with the knowledge of the above graph, the blue of European nations quickly disappears as it is replaced by the yellow of Asia in the current year. Then the yellow is subsequently replaced by more of the red of Africa by 2050.

The world is changing. Rapidly. And it is important for people to understand where the trends of population are heading, for these trends predict where substantial development and social change is to take place. It would be best for the world to be a step ahead with these developments, as opposed to needing to shamefully catch up.
