The mystery of Japan's missing centenarians explained


This report elucidates the issue of Japan’s missing centenarians, which was uncovered in 2010. We provide the latest figures from verification efforts, discuss sources of centenarian information in Japan, examine possible causes, and evaluate the effect of the missing centenarians on official statistics. In Japan 234,354 people registered before 1910 remained on the family registers in 2010, without being crossed out. They would have been 100 years old at least and represent 0.5% of the births recorded between 1872 and 1910. The impact of this group on life expectancy statistics, however, is effectively nil.
