Question

Calculate and Interpret Adjusted/Standardized and Unadjusted Mortality Rates

Using these data, calculate and record your answers in the blanks below. This exercise is meant to illustrate the effect of age composition on Crude Death Rates (CDR).

	FAMILY LAND Suburban Population			SUN CITY Retirement Community
	Mid year population	Death Rate (per person)		Mid Year Population	Death Rate (per person)
0-14	1125	0.025		1132	0.025
15-29	2342	0.013		875	0.013
30-49	1508	0.026		1736	0.026
50+	503	0.110		3458	0.110

Answer 1

The answers to questions are got as follows:

Question	FAMILY LAND	SUN CITY
Total Population Size	5478	7201
Number of deaths to persons 0-14	1125 X 0.025 =28.125	1132 X 0.025 = 28.3
Number of deaths to persons 15-29	2342 X 0.013 = 30.446	875 X0.013 = 11.375
Number of deaths to persons 30-49	1508 X 0.026 = 39.208	1736 X 0.026 = 45.136
Number of deaths to persons 50+	503 X 0.110 = 55.33	3458 X 0.110 = 380.38
Total Number of Deaths	153.109	465.191
Crude Death Rate (CDR), per 1000	(153.109/5478) X 1000 = 27.9498	(465.191/7201) X 1000 = 64.6089
Percentage of total population age 50+	(503/5478) X 100 = 9.1822 %	(3458/7201)X 100 = 48.0211
