A Study on Proportional Mortality Indicator of Community
Author information

1966 Volume 32 Issue 4 Pages 115-121


In order to examine the usefulness of proportional mortality indicator for evaluating health level of a community, the indicator of each health center controlled community of the Iwate Prefecture were investigated using vital statistics of the Prefecture in 1960, and the associations between proportional mortality indicator and other mortality or demographic indicator were studied. Proportional mortality indicator proved to be closely related to the agedness of population both in male (r= +0.4658) and in female (r=+0.7374). The demographic structure of the population of a community is rather a result of internal migration, especially urban-rural migration, than a result of experiences of mortality and natality . Taking these facts into consideration, it has been concluded, according to the author's opinion, that proportional mortality indicator, though being a useful comprehensive health indicator to evaluate health level of a country, is not so useful to evaluate health level of a community.
