The graph is not "drawn out" but the points are given with one axis as (mortality per 100 in Old group, and the other axis as Mortality per 100 in Young group. 

Practice Death Rate Calculations

The graph shows some imaginary mortality statistics for several countries. For the sake of simplicity, the

age-dependence of mortality is reduced to just two groups:

· young people age 40 and below

· older people age 41 and above.

Mortality (per 100) in Old Group

Mortality (per 100) in Young Group

A(Old=5, Y=4)

B(Old=7, Y=9)

C(Old=2, Y=8)

D(Old=9, Y=3)

1. Calculate the overall mortality rate (per 1000) in each country. Assume that the populations

are as follows:

Country Old Young

A 200 800

B 100 900

C 600 400

D 400 100

2. Calculate an age-adjusted mortality rate for each country. Take this as the standard population

Country Old Young

Standard Pop. 400 600
