Forecasts by the United Nations on 17 June project that the world’s population of 7.7 billion today will rise by 26% to 9.7 billion by 2050 and by a further 12% to 10.9 billion by 2100.
India will become the world’s most populous country by 2030, increasing to 1.6 billion in 2050, with China rising then falling back to the current level of 1.4 billion.
Nigeria is on course to take third place in 2050, having jumped from 95 million in 1990 to 201 million in 2019 and reaching 401 million in 2050.
Indeed, Sub-Saharan Africa will account for more than half of global population growth up to 2050, doubling over the next 30 years to 2.1 billion. With a current birth rate of 7 children per family, Niger’s population could even triple.
In contrast, 27 countries have had declining populations since 2010 and 55 countries are predicted to experience declines up to 2050. Some of the biggest reductions have been in East Europe.
Syria, Bangladesh and Venezuela have lost the highest numbers due to emigration, with the United States and Germany seeing the greatest immigration.
Average life expectancy is expected to continue increasing. In 1990 it was 64.2 years. For 2019 it has increased to 72.6 years. By 2050, it is expected to reach 77.1 years.
I’m hoping for more years, too. Along with quality and sustainability.
