2022 Deaths – All Causes – Female – Ages 85-89 | Alberta, Canada

2022 vs New Normal™ for elderly women aged 85-89 in Alberta

1. 2,273 of 2,273 total deaths were from All Causes
2. 100.00% of all deaths were from All Causes
3. This is down 2% compared to Old Normal rates.
4. 2,323 of 2,323 total deaths would have been expected under Old Normal conditions.
5. 50 fewer than expected deaths from All Causes in 2022.
6. 1,892 fewer than expected deaths from All Causes (2015-2022)

1. To show this year’s deaths from All Causes are down 2% compared to Old Normal rates, we need to calculate the rates for both 2022 and for the Old Normal.

Remember, death rates are calculated to answer these questions:

• “How many elderly women aged 85-89 were there?” and
• “How many of them died from All Causes?”

The following 2 charts provide this information:

From the charts, we can see that in 2022, 2,273 of 26,636 elderly women aged 85-89 living in Alberta died from All Causes.

2,273 ÷ 26,636 = 0.08534 (2022 CDR)

We’ll use the table below to calculate our Old Normal rate for deaths from All Causes

The table shows there were a total of 23,315 deaths from All Causes among 267,381 elderly women aged 85-89 living in Alberta in the 14 years immediately prior to the New Normal™.

23,315 ÷ 267,381 = 0.08720 (Old Normal CDR)

We can use the Old Normal rate to predict this year’s deaths:

2022 pop X Old Normal CDR = expected deaths

26,636 X 0.08720 = 2,323 expected deaths

The difference between actual and expected deaths shows lives saved or lost:

2,273 – 2,323 = -50

Dividing the actual deaths by the expected deaths gives us the comparative rates:

2,273 ÷ 2,323 = 0.9785

This reveals 50 lives saved and is 97.85% of what we expected (a decrease of 2%) in deaths from All Causes among elderly women aged 85-89 living in Alberta in 2022, as compared to the Old Normal.

This is the same method used by Public Health to calculate the 5-yr CDR (Cumulative Death Rate):

13,408 ÷ 174,893 = 0.07666 (5-yr CDR)

26,636(2022 pop) X 0.07666 = 2,042 expected deaths

The difference between actual and expected deaths:

2,273 – 2,042 = 231 or 231 lives lost

Divide actual deaths by expected deaths:

2,273 ÷ 2,042 = 1.1130 or an increase of 11%

for deaths from All Causes among elderly women aged 85-89 living in Alberta in 2022, as compared to the previous 5 years.

Compare our Old Normal to the 5yr CDR. Does it tell the same story your TV does?

Finally, the same method can also be used to compare our Old Normal rate to the New Normal™ rate:

New Normal™ population X Old Normal rate = expected deaths

201,529 X 0.08720 = 17,573 expected deaths

The difference between actual and expected deaths:

15681 – 17,573 = -1,892 or 1,892 lives saved

Dividing the actual deaths by the expected deaths:

15,681 ÷ 17,573 = 0.8922 or a decrease of 11%

in deaths from All Causes among elderly women aged 85-89 living in Alberta in the New Normal™, as compared to the Old Normal.
