One-fifth of Japan's population is now aged 70 yrs or above
Over one-fifth of Japan's population is now aged 70 years or above and they account for 20.7% of the country's population, new government data has revealed. The elderly people (those aged 65 or above) make up 28.1% of the population. The rise in Japan's ageing society has been attributed to low birthrates, which have led to a shrinking population.
