It’s finally happened. After years, if not decades, of warnings about Japan’s aging population and its low birth rate, the day is here. Japan’s official census shows that the country’s population has shrunk.And not by an inconsiderable amount either: The 2010 census showed a population of 128,057,352, but the 2015 figure, released Friday, shows just 127,110,000.Japan’s population had shrunk by almost 1 million people in five years.While data on birth and death rates has long given clear evidence that Japan’s population was on the decline, this is the first time since records began that the census has confirmed the nation’s population has actually dropped (the blip between 1940 and 1950 in the chart is largely due to the fact that many Japanese soldiers were stationed abroad and Okinawa island, then controlled by the United States, was not included in the census).
