In a post
published in this blog in December 2015, Julio A. Gonzalo and I analyzed
the data on the world population provided in 2012 by the UN, along with their future
forecasts until the year 2100. A few months ago, the UN has updated those data
and forecasts with the figures
available in 2019. As seven years have elapsed, it is possible to compare the
forecasts made in 2012 with the real situation just now.
