For the two populations below, calculate and compare the crude death rates. Then age-adjust population B using population A as the standard. Compare the death rates again. Indicate which comparison is more meaningful. Use a rate base of 1,000.
Population A
Age (years) Population Number of deaths
15-29 1,000 34
30-49 4,000 26
50+ 6,000 121
Population B
Age (years) Population Number of deaths
15-29 5,000 120
30-49 2,000 10
50+ 1,000 10
What is the standardized morbidity ratio (SMR) for Population B using Population A as the standard?
