The principal objects of this study are to provide a relatively simple method which will be useful in observing the health status in rather smaller areas where ever lacked universally comparable health indices through the whole parts of the country and to further encourage the preparation and publication of such statistical material extensively. This experimental study covering a period of three years of 1975,has the areal coverage of seven administrative areas. They are located in the southern part of Izu Peninsula in Shizuoka Prefecture. Following indications are the major findings which have been found by this analytical study. 1. The population structure obervation indicates that Higashi-Izu Town has the almost similar proportion of the aged population to that of the nation's average. However, it can be said that the remaining six areas observed have larger rates in the proportion of the aged population than the nation's average. 2. It can be concluded that only one area, Higashi-Izu Town, maintains a relatively better maternal and child health status, such as infant mortality rate, perinatal mortality rate, etc, comparing to the national level. Besides, the remaining six areas show the comparatively lower than the national average. 3. The crude death rate reveals that all of the observed areas indicate comparatively higher rates rather than the nation's average. While, the standardized mortality ratio (SMR) has been found that three areas, namely, Kawazu Town, Nishi-Izu Town and Shimoda City, are showing relatively lower rates, i.e., 93 for Kawazu Town, 94 for Nishi-Izu Town and 101 for Shimoda City, and the remaining three areas show relatively higher rates than the naitonal average which is assumed as a standard of 100 in this paper. 4. Outcomes from the comparative analysis with the SMR for major causes of death. Cerebrovascular diseases : Among the seven areas selected, two towns, have the slightly higher SMR-Rs of 127 and 118 respectively. In accordance with the vital statistics data, these two areas have lower SMR-Rs from heart diseases. Heart diseases : The SMR-Rs from heart diseases are showing that in particular the two areas, namely, Kamo Village and Minami-Izu Town, indicate the relatively higher mortality with the SMR-Rs of 135 and 129 respectively. And it is interesting to note that these two areas have on the contrary relatively low SMR-Rs from cerebrovascular diseases. All forms of cancer : It has been revealed that the computed SMR-Rs for this cause of death represent only one area, Kamo Village, is giving the figure of 120 and on the other hand the remaining six areas show almost similar mortality from this disease or in few cases lower than the nation's average. Concludingly, it can be mentioned that this sort of recomputation and comparative analysis works will ideally be made by the vital statistics authority who keeps the enough source data. The work should be extended to all of the areas and districts, namely, 858 health center districts and 3369 local administrative areas. Additionally, this recalculation work may cover the period of at least three or five years around the population census year. It would be further desirable to have an assembled printed material containing the above vital statistics indices for all divided areas in Japan.
