QuestionUse Figure 7D. 2 and these facts to answer the following question. The death rate in 1917 (the year before the influenza pandemic) was 2300 deaths per 100,000 . The death rate in 1918 (the year of the influenza pandemic) was 2550 deaths per 100,000 . The U.S. population in 1917-1918 was approximately 105 million.
What was the percentage increase in the death rate over the previous year in 1918 and in 2020 ? By this measure, which pandemic was worse?

Studdy Solution
STEP 1
1. The death rate in 1917 was 2300 deaths per 100,000.
2. The death rate in 1918 was 2550 deaths per 100,000.
3. We are calculating the percentage increase from 1917 to 1918.
4. The U.S. population is not directly needed for the percentage calculation.
5. We are not provided with data for 2020, so we will focus on 1918.
STEP 2
1. Calculate the difference in death rates between 1918 and 1917.
2. Calculate the percentage increase in the death rate from 1917 to 1918.
3. Compare the percentage increase to determine which pandemic was worse (if data for 2020 were available).
STEP 3
Calculate the difference in death rates:
STEP 4
Calculate the percentage increase:
STEP 5
Round the percentage increase to the nearest whole number:
The percentage increase in the death rate over the previous year in 1918 was:
