Question: According to a census data (1970), 4,648,377 persons lived in a rural town in West Malaysia. During the same year, census data showed that 3,409,169 persons were residing in Washington State, U.S.A., a predominantly industrialized society. Mortality data indicated the age-specific death rates for Malays in West Malaysia exceeded those for residents of Washington State for every age group by substantial margin. Yet the overall crude death rate for Washingtonians exceeded that for Malays (8.8 per 1,000 vs. 7.6 per 1,000).

From the data in the table above, perform calculations and answer the following questions:

   (a) Calculate the age-adjusted death rate for Malays, using the population of Washington State as the standard population. (8 points)

     (b) In contrast to the crude death rate for Malays, how does the adjusted Malay rate compare with the crude rate for Washington State? (8 points)

Answer 1

1. To calculate age adjusted death rate first we have to calculate age specific mortality rate .

Age specific mortality rate = number of deaths due to any disease /total population at that point of time × 100000 and then total sum of them

Mortality rate of each specific age group is given hence add them = 130 .1 ~ 130 is the age adjusted death rate for Malays by using the population of Washington state .
