23 Jun 2017 --- The current world population of 7.6 billion is expected to reach 9.8 billion in 2050 and the number of persons aged 60 or above is expected to more than double during the same period, according to a new UN report launched this week. With roughly 83 million people being added to the world’s population every year, the upward trend in population size is expected to continue, even assuming that fertility levels will continue to decline.
