PRB’s population projections in the 2015 Data Sheet show world population reaching 9.8 billion by 2050, up from an estimated 7.3 billion now, though the projections mask wide variations among countries, notably:
National populations are projected to more than double in 40 countries, the vast majority of which are in Africa. Niger’s population is projected to more than triple.
Thirty-four countries are projected to have smaller populations in 2050 than they do today. The biggest absolute decline would be in Japan, shrinking by 30 million people, while the biggest percentage decline would be Latvia, falling by 30 percent.
