DEATH RATES IN A GROUP OF INSURED PERSONS. COMPARISON OF DEATH RATES FOR PRINCIPAL CAUSES, SEPTEMBER AND OCTOBER, The accompanying table is taken from the Statistical Bulletin of the Metropolitan Life Insurance Co. for November, 1922, and presents the mortality experience of the company for September and October, 1922, and for October and year, 1921. The rates are based on a strength of approximately 14,000,000 insured persons. The mortality record for this group continues to show a favorable health situation, the rate for October, 7.86 per 1,000, being only slightly higher than that for September, 7.44. This rise in mortality is to be expected, in view of the seasonal increase in the number of deaths from respiratory diseases and diphtheria.

The following figures show the decline in the death rate from typhoid fever among the industrial policyholders of the company in American and Canadian cities during the 12-year period 1911-1922, and evidence the fact that modern sanitary science is conquering typhoid. The death rate from this disease in this group of persons shows practically an uninterrupted decline from 22.8 per 100,000 in 1911 to 6.7 in 1920 and 1921, and to 5.9 (estimated) in 1922. DECLINE IN MALARIA DEATH RATE.
