QUESTIONS:

1) Use the data on all-cause mortality and unintentional injury deaths in Table 1. For each of the following questions write out the full formula you are using, then perform the necessary calculations to get an answer. Show your work in order to get full credit or to get partial credit in the case of an incorrect answer.

a) (4 points) What is the sex ratio of males per 1,000 females (use the total population counts)?

b) (4 points) What was the sex specific mortality rate (per 100k) for females in 2002?

( HAPP 420 )

( 1 )

c) (4 points) What was the age-specific mortality rate (per 100k) for all causes for females in the age group 0-4 in 2002?

d) (4 points) What was the unintentional-injury-specific mortality rate (per 100k) for females in 2002?

e) (4 points) What was the proportional mortality rate for unintentional injury (in %) for females in 2002?

f) (8 points) What is the age-specific mortality rate for unintentional injury (per 100k) for females in 2002 for the ages 15-24 and also for ages 65+?

g) (4 points) In the group portion of this lab, you should have calculated the sex-specific mortality rate for males to be 846.6 per 100,000 males. Compare this answer to 1b) above. Which is higher? Why might these two numbers be misleading in the same way that crude mortality rates are?
