Question

1. Tables 4.1 and 4.2 summarize the population size and number of deaths in Alaska and Florida in 2003. Use these tables to answer the questions that follow.

Table 4.1: Population and number of deaths by age in 2003 for Alaska

Age in Years	No. of deaths	Population	% of population	Death rate per 100,000
< 5	89	48,680	7.5
5-19	99	163,629	25.22
20-44	385	233,205	35.94
45-64	885	162,706	25.08
65+	1,722	40,598	6.26
Total	3,180	648,818	100.0

Table 4.2: Population and number of deaths by age in 2003 for Florida

Age in years	No. of Deaths	Population	% of population	Death Rate per 100,000
<5	1,891	1,054,865	6.2
5-19	1,330	3,301,582	19.40
20-44	9,506	5,690,076	33.43
45-64	28,455	4,075,162	23.94
65+	127,475	2,897,383	17.02
Total	168,657	17,019,068	100

Round all final answers to 2 decimal places. For questions A-D, show work in the space & write the answer in table.

Hint for question 4 A-D: These should NOT be age-adjusted—so no multiplying by the % in the population.

1. Calculate the age-specific death rates per 100,000 for Alaska.
   • <5:
   • 5-19
   • 20-44:
   • 45-64
   • 65+:

2. Calculate the total crude death rate per 100,000 for Alaska.

• Total:

3. Calculate the age-specific death rates per 100,000 for Florida.

• < 5:
• 5 - 19
• 20-44:
• 45-64
• 65+:

4. Calculate the total crude death rate per 100,000 for Florida.

• Total

5. How do the crude death rates (total death rate) for Alaska and Florida compare?

6. Are the age-specific death rates similar for Alaska and Florida? Justify your answer.

7. Is the age distribution similar for the two populations? Justify your answer.

8. What likely accounts for the very different crude rates in Alaska and Florida? Hint: It is NOT that one total population size is much larger than the other. When rates are expressed per some base of 10 (in this example per 100,000), it simply means out of 100,000 people. So, all rates in this example are out of 100,000 people (regardless of the underlying total population).   

1. Now, assume that the death rates in Tables 4.1 and 4.2 were used to calculate an age-adjusted rate using the US population as the standard. The age-adjusted death rate for Alaska 737.45 deaths per 100,000, and for Florida it was 789.61 per 100,000.
   1. How do these age-adjusted rates compare to each other?

2. How do the age-adjusted rates compare to the total crude rates that were calculated for Alaska and Florida?

3. What do these results indicate about the influence of age?
