Every single year, the world’s population is increasing by a staggering sum of 83 million people. Currently, there are about 7.6 billion people in the world. It is expected that by 2050, there will be just short of 10 billion.
Population growth trends are unevenly distributed across the world. While some countries are rapidly expanding, others are shrinking drastically.
For each development whether growth or decrease comes with its own challenge for governments. Countries whose populations are on the decline have to think about how to support older people when there are fewer young workers to generate and pay into government funds.
Countries with a booming young population have to deal with how to feed, cater for them and provide education and healthcare.
Fertility, followed by mortality and then migration are the three major things that affect Wolrd’s population.
Here are some key facts about the world’s population, taken from the latest UN World Population Prospects.
