Generation life table can be constructed by following a cohort of, say, 100, 000 persons from the moment of birth through successive calendar years, recording, in each year of life, the actual number of survivors, until all have been accounted for by death . In order to construct the generation life tables, it is necessary to make use of the data of death rates for the period of more than 100 years. But in the pre-census years, the death reports were incomplete and the populations were domicile, and not census enumeration. Hence these early life tables by the Bureau of Statistics before the census are quite unreliable. Therefore Matsuura and Mizushima attempted to reform these pre-census life tables. We used the estimated values of q0-q100 on the basis of these reformed life tables and many reliable life tables, so that we constructed the generation life tables of persons born in 1895. The tables shown here seem more reasonable and appropriate than those which have been known until the present day.
