Outline of Final Research Achievements |
What were the characteristics of Japans oldest-old population during the Edo Period (1603-1867)? Compared to todays, was it larger, smaller, or similar in size and ratio? To approach this issue, I carefully examined historical records of the research fields for 1720 to 1872 and determined the number of those with extremely long longevity. Next, I calculated the ratio of oldest-old people to the base population, the result of which was compared to the figures from national population census conducted in 1888 or after. As a result, I concluded that in the early modern period, only a few Japanese people enjoyed extremely long longevity, with those over the age of 80 being below 11 in every 1,000 people (5‰ to 11‰ of the base population), and those over the age of 90, 0.5 person (0.3‰ to 0.5‰ of the base population). In other words, the super aging of population in the Japanese society today is a revolutionary event which has been observed over the last three decades (from the 1980s).
