Globally, about 25 percent of the population is under 15 years of age and 10 percent is over 65 years of age. Africa has the youngest population worldwide. On the continent, 40 percent of the population are below 15 years, and less than three percent are above 65, indicating the low life expectancy in several of the countries. In Europe, on the other hand, a higher share of the population is above 65 years than the population under 15 years.
Fertility rates
The high share of children and youth in Africa is underlined by the high fertility rates on the continent. For instance, South Sudan and Burundi have some of the highest population growth rates globally, reaching around five percent and 3.7 percent, respectively. However, about 50 percent of the world’s population live in countries with low fertility, where women have less than 2.1 children. Some countries in Europe, like Latvia and Lithuania have experienced a population decline of one percent, and in the Cook Islands, it is even above two percent. In Europe, the majority of the population was previously working-aged adults with few dependents, but this trend is expected to reverse soon and it is predicted that by 2050, the older population will outnumber the young in many developed countries.
Growing global population
As of 2023, there are 8.1 billion people living on the planet, and this is expected to reach more than eight billions before 2040. Moreover, the global population is expected to reach 10 billions around 2060, before slowing and then even falling slightly by 2100. As the population growth rates indicate, a significant share of the population increase will happen in Africa.
