For the first time since 1979, according to this article in the Japan Times, Tokyo is home to 10% of Japan’s total population. The primary reason: employment opportunities.
But that’s not the only thing that the census discovered. Nine other prefectures saw a shift in population towards the urban centers, while all across Japan, the population of people aged 65 and older increased:
Tokyo was the only prefecture that saw an increase in people aged 14 or younger, while all 47 prefectures posted rises in the population aged 65 or older.
In six prefectures, people aged 75 or older outnumbered those aged 14 or younger.
The national population was estimated at 127.77 million, almost unchanged from a year ago. But the population data marked for the first time a natural decrease since they began to be compiled in 1950. Deaths outstripped births by 2,000.
