Schematic Representation of the Calculation of Age Adjusted Excess Death. Populations and total amounts of death on a single year are computed as sum of weekly data and used to obtain the mortality values for the reference years (2017–2019) for each of the age strata. The average of this value is taken as the reference mortality for that strata. Expected deaths for a non COVID scenario for 2020 and 2021 are obtained from the population and reference mortality data for each strata. Excess deaths are calculated as the difference between the actual deaths and the expected deaths. Expected and excess deaths for the non-age adjusted case are also reported for comparison. The table reports the real values for Germany as an example. This table is provided as Excel in the Supplement so that method can be easily used on other data.
