Standardisation (cont.)
Now we can find the total number of deaths that would have been expected if Sweden had had the same age structure as the standard population.
If we divide this by the total number of person-years in the standard population, we get an age-adjusted (or age-standardised) mortality rate for Sweden.
| Age (years) | Mortality Rate for Sweden (per 1000 pyrs) |
Standard Population | Expected No. of deaths |
|---|---|---|---|
| 0-29 | 0.45 | 56,000 | 25.2 |
| 30-59 | 2.4 | 33,000 | 79.2 |
| 60+ | 42.4 | 11,000 | 466.4 |
| Total | 100,000 | 570.8 |
| Age adjusted mortality rate: | = 570.8 / 100,000 | = 5.7 per 1000 pyrs |
