The tabulation and analysis of the data based upon the death certificates aid in measuring the effects of health services and in establishing the need for health programs. As data of the present studies the following items on every death were transcribed from the death certificates : place, date and cause of death, age, sex and the occupation of the head of a household. This series of reports is the result of investigation of the four districts, Eigenji-cho, Kutsuki-mura, Shigaraki-cho and Yogo-mura. The deaths treated here are those who died during 3050 years up to 1965 and total 23, 246. In this report, various statistics of mortality are analyzed, and the following results are obtained : 1) The hygienic effects of social improvement suffered little change during 19151940. While, a marked increase in the average duration of life has occurred since 1949, showing the advances in medical knowledge and hygienic living conditions. 2) It has been made sure that the short life of the people during 19151949 was mainly due to the high death rate of the age-group 04 years. Moreover, it has been found that the relative improvement in mortality has been made not only by the infant and old ages but also by the adult age since 1955. 3) The comparison of various indices: average age of death, proportional mortality indicator, average length of life and rate of survivors at a certain age to the total population etc., provides the ranking of relative longevity among the four districts. 4) Yogo-mura is the most longevous village both in males and females over the whole period.
