Introduction
A life table considers a hypothetical cohort and assumes that it is subject to the age-specific mortality rates realized by an actual population for a particular period. For example, a life table for 2005 assumes a hypothetical cohort subject, throughout its lifetime, to the age-specific mortality rates realized by the actual population for 2005.
We hereby present the Complete Life Tables for Japan 2005. In Japan, the Ministry of Health, Labour and Welfare have prepared two series of life tables ―― the Complete and the Abridged Life Tables. The former have been constructed every five years based on the Annual Vital Statistics and the Population Census. The latter have been on the Provisional Annual Vital Statistics and the Population Estimates. The Complete Life Tables for Japan were first prepared for the period 1891-98 and the life tables presented here are the 20th ones.
After the end of World War II, the improvements in Japanese life expectancies were remarkable in ten years. Since 1955, life expectancy has not increased as much as before, but it has been steadily improved and reached 78.56 years for males and 85.52 years for females in 2005.
The trends in life expectancy since the 1st life tables are shown below.
