The year 2020 will be a seminal one for Japan, with the country's capital home to the 31st Summer Olympiad and adult diapers set to outsell their baby counterparts.
The world is getting older, developed countries especially. Even in emerging markets like Brazil, the total fertility rate has dropped from 6.2 live births per women to 1.8, below the so-called "replacement rate."
Deutsche Bank global strategist Sanjeev Sanyal recently forecasted that world population will peak around the year 2055 at 8.7 billion before declining to eight billion by 2100.
Now, thanks to coder Martin De Wulf and U.N. data, we can really visualize these startling changes. De Wulf arranged population figures to make a set of familiar aging visualizations called population pyramids.
We chose 15 countries and show you the transition from 2000 to 2100 in 10-year intervals.
