The planet could be much more crowded by the end of the century than previously thought, according to a new report by University of Washington researchers.
That contradicts a general consensus that world population growth is likely to stabilize before long. The population has been expected to rise from the current seven billion or so to about nine billion, before leveling off and possibly declining.
But new projections, based on new statistical models, suggest the numbers will not tail off after all. Instead, statistician and sociologist Adrian Raftery said we could hit 11 billion and counting by century’s end.
