For the purpose of investigating the factors relating to the recent average life span (e₀) in Japan, relationships were studied between e₀ and medical and health indices (27 itmes), food and others (21 items) about 10 and 5 years before the e₀, from point of annual changes and geographical distributions of items. Coefficients of serial correlation and geographical correlation were positive and significant for men between e₀ and number of pharmacists and quantity of milk purchase about 10 and 5 years before the e₀, watersupply extension rate 5 years before the e₀, so were geographical correlation coefficients between changes in e₀ by year and in above 2 items. For women above correlations were positive and significant in coefficients between e₀ and number of clinics 10 years before the e₀. On the other hand those correlations were negative and significant in coefficients for men between e₀ and livelihood protection rate 5 years before the e₀. These results suggest that number of pharmacists, watersupply extension rate and quantity of milk purchase relate positively to the recent average life span for men and livelihood protection rate does negatively, and number of clinics relate positively for women in Japan.
