AGE-INCIDENCE OF CAUSES OF INFANT MORTALITY 



Let us now see if the particulars of mortality will give us 

 any approximate measurements in this obscure area. 



The Census Mortality Report for 1908 contains, on page 19, 

 a table giving average and median ages at death according to 

 causes and classes of causes; an interesting and valuable table, 

 which one wishes might be regularly published. Eighteen times 

 in the course of this table we find median ages under one year, 

 21 times at less than two years, and 26 times at less than three 

 years. 



In Table No. 7 of the same volume the age distribution is 

 given for deaths falling under 145 of the titles comprised in the 

 International Classification (or tabular list) of Causes of Death 

 for Statistical purposes. There are entries of mortality in the 

 first year of life under 130 of these titles. I have selected those 

 titles whose median ages are less than one year, 15 in number, 

 and these, with the nine additional titles most intimately related 

 to infancy, are shown in Table I.
