, 1. The data below shows hypothetical mortality rates in city A due to lung cancer in non-Hispanic
whites stratified by age:
Age Number of Total Population Mortality Rates Expected
Deaths in non- of non-Hispanic (per 100,000 Number of
Hispanic Whites Whites persons) in Deaths in Non-
Asians Hispanic Whites
0-10 42 85,000 30
11-20 74 125,000 20
21-30 65 122,000 25
31-40 75 150,000 40
41-50 300 160,000 70
51-60 500 140,000 135
61-70 900 165,000 300
71+ 2,000 90,000 1,700
A. Based on the above information, use the appropriate measure of standardization to adjust
for age (HINT – You will need to fill in the last column of the above table). Show all
calculations. (10 points)
Expected Deaths in Non-Hispanic Whites = (Population Size of non-Hispanic whites / 100,000) *
Mortality Rate in Asians
Expected Deaths in Non-Hispanic Whites of Age 0-10 = (85,000/100,000)*30 = 25.5
Expected Deaths in Non-Hispanic Whites of Age 11-20 = (125,000/100,000)*20 = 25
Expected Deaths in Non-Hispanic Whites of Age 21-30 = (122,000/100,000)*25 = 30.5
Expected Deaths in Non-Hispanic Whites of Age 31-40 = (150,000/100,000)*40 = 60
Expected Deaths in Non-Hispanic Whites of Age 41-50 = (160,000/100,000)*70 = 112
Expected Deaths in Non-Hispanic Whites of Age 51-60 = (140,000/100,000)*135 = 189
Expected Deaths in Non-Hispanic Whites of Age 61-70 = (165,000/100,000)*300 = 222.75
Expected Deaths in Non-Hispanic Whites of Age 71+ = (90,000/100,000)*1700 = 1530
Age Number of Total Population Mortality Rates Expected
Deaths in non- of non-Hispanic (per 100,000 Number of
Hispanic Whites Whites persons) in Deaths in Non-
Asians Hispanic Whites
