Another way of looking at the data is to consider the specific increase in the number of influenzaand pneumonia-related deaths in one age group between 1917 and 1918. You can calculate this by dividing the number of deaths in 1918 by the number of deaths in 1917. For instance, if you look at the age group , 1 year, divide the number of deaths in 1918 (4,540.9) by the number of deaths in 1917 (2,944.5). The increase in deaths during 1918 is approximately 1.5 times the 1917 deaths. How many times greater is the 1918 death total than the 1917 death total for 5- to 14-year-olds?
