2022 Deaths – Unknown Causes – Female – 75-79 | Massachusetts, United States

2022 vs New Normal™ for elderly women aged 75-79 in Massachusetts

1. 839 of 3,672 total deaths were from Unknown Causes
2. 22.85% of all deaths were from Unknown Causes
3. This is down 2% compared to Old Normal rates.
4. 851 of 4,106 total deaths would have been expected under Old Normal conditions.
5. 12 fewer than expected deaths from Unknown Causes in 2022.
6. 434 fewer than expected All Cause deaths in 2022.
7. 103 excess deaths from Unknown Causes (2015-2022)
8. 2,946 fewer than expected All Cause deaths over the first 8 years of Massachusetts’s New Normal™.

1. To show this year’s deaths from Unknown 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 75-79 were there?” and
• “How many of them died from Unknown Causes?”

The following 2 charts provide this information:

From the charts, we can see that in 2022, 839 of 130,597 elderly women aged 75-79 living in Massachusetts died from Unknown Causes.

839 ÷ 130,597 = 0.00642 (2022 CDR)

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

The table shows there were a total of 9,801 deaths from Unknown Causes among 1,503,628 elderly women aged 75-79 living in Massachusetts in the 15 years immediately prior to the New Normal™.

9,801 ÷ 1,503,628 = 0.00652 (Old Normal CDR)

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

2022 pop X Old Normal CDR = expected deaths

130,597 X 0.00652 = 851 expected deaths

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

839 – 851 = -12

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

839 ÷ 851 = 0.9841

This reveals 12 lives saved and is 98.41% of what we expected (a decrease of 2%) in deaths from Unknown Causes among elderly women aged 75-79 living in Massachusetts 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):

5,033 ÷ 754,413 = 0.00667 (5-yr CDR)

130,597(2022 pop) X 0.00667 = 871 expected deaths

The difference between actual and expected deaths:

839 – 871 = -32 or 32 lives saved

Divide actual deaths by expected deaths:

839 ÷ 871 = 0.9615 or a decrease of 4%

for deaths from Unknown Causes among elderly women aged 75-79 living in Massachusetts 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

885,010 X 0.00652 = 5,769 expected deaths

The difference between actual and expected deaths:

5872 – 5,769 = 103 or 103 lives lost

Dividing the actual deaths by the expected deaths:

5,872 ÷ 5,769 = 1.0163 or an increase of 2%

in deaths from Unknown Causes among elderly women aged 75-79 living in Massachusetts in the New Normal™, as compared to the Old Normal.
