The world population has grown very rapidly because of the increasing numbers of people surviving to reproductive age. It is accompanied by major changes in fertility rates, increasing urbanization and accelerating migration. According to a report of the United Nation, in the next 30 years, the world’s population is expected to increase by 2 billion persons and it could peak at nearly 11 billion around 2100.

Factors influencing the World’s Population Growth

China and India are the most populous countries in the world. Africa is the fastest growing continent and is expected to have more than half of global population growth between now and 2050. The population is shrinking in Europe. The factors that influence the world’s population growth are:

  • Fertility rates: Population growth is dependent on fertility. Global fertility is estimated to fall from 2.5 children per woman in 2019 to 2.2 in 2050.
  • Increasing longevity: It refers to life expectancy. It is expected to rise from 72.6 years in 2019 to 77.1 years in 2050.
  • International migration: Some countries send or receive large numbers of economic migrants. More than one million migrants inflowed in fourteen countries between 2010 and 2020.
