had dropped to the extent of more than 16,500, the sum of the 

 decreases in the previously named age-groups. 



Assuming that the birth-rate for the six years was substan- 

 tially uniform (the birth rate in the Census year 1900 was 27.2 

 per 1,000 of mean population in the United States), the natural 

 growth of the population in the Registration Area between 1900

and 1905 (amounting to nearly 3,000,000) would indicate an 

 increase of about 81,000 in the probable number of births in 

 1905 as compared with 1900, and at the ratio of deaths under 

 age 1 to living births in the Registration Area in the Census 

 year 1900 (149.4 per 1,000) this increase in births would have 

 involved an increase of more than 12,000 in the number of 

 infant deaths in 1905 as contrasted with the number in 1900.
