The current world population of 7. The report, World Population Prospects: the Revision, notes that the population of developed regions will remain largely unchanged at around 1.
In contrast, the 49 least developed countries are projected to double in size from around million people in to 1. Compared to previous assessments of world population trends, the new projected total population is higher, mainly due to new information obtained on fertility levels of certain countries. For example, in 15 high-fertility countries of sub-Saharan Africa, the estimated average number of children per woman has been adjusted upwards by more than 5 per cent.
Wilmoth added that changes in fertility rates over the next few decades could have major consequence for population size, structure and distribution in the long run. Wilmoth warned that the continent is already facing challenges in providing care and support for a rapidly aging population.
Overall, life expectancy is projected to increase in developed and developing countries in future years. At the global level, it is projected to reach 76 years in the period and 82 years in By the end of the century, people in developed countries could live on average around 89 years, compared to about 81 years in developing regions.
