The data is based upon weekly deaths data from eurostat spanning from 2010 to 2023. For some countries (such as Germany) data is unavailable; and for others it is only available from 2015 onwards.
Countries: AT, BE, BG, CZ, DK, DE, EL (Greece), ES, FR, IT, HU, NL, PL, PT, RO, FI, SE, NO.
Source for Weekly Deaths (Eurostat): Eurostat table: Deaths by week, sex and 5-year age group.
Source for Vaccination data: European Centre for Disease Prevention and Control.
Source for Population Estimates (Eurostat and UN): Eurostat table: Population on 1st January by age, sex and type of projection.
In order to estimate weekly excess mortality we perform a 2-step approach to estimate the baseline deaths. The first step is by estimating the trend in death rates using annual data as described in our methodology papers, while using method 2C.
The second step is to estimate weekly excess deaths by comparing deaths or death rates in a given week with the average death rate, which is computed using the average weekly frequency of deaths over a period of N-years (typically 5 to 10 years depending on the data availability). By using both methods in conjunction we obtain a trend adjusted and week of year adjusted estimate for excess mortality.
Our analysis computes both excess death rates and excess deaths, which are obtained by multiplying the excess death rates with population estimates for the given year.
Weekly data provides a granularity that allows us to investigate the impact of immediate vaccination deaths, lockdowns, or other effects, on excess mortality.
The following chart shows the analysis of excess mortality for 2020, 2021, 2022 and 2023, for different age groups. The Covid-19 vaccinations data (right hand scale) refers to the total accumulated doses for 2021 and 2022, as a percentage of the respective age group population.
The user can specify the European country and the method for estimating excess mortality. It should be noted that some countries do not provide either the Covid-19 vaccination data or weekly deaths data to Eurostat, such as for example Germany.
The following chart allows the user to compare the trends in excess mortality during 2020,2021, 2022 and 2023, for the different age groups.
This chart is particularly interesting to investigate excess mortality for older versus younger individuals as the pandemic evolved. In most developed countries, Covid-19 vaccination started to be rolled out in early 2021 and accelerated in March 2021. Vaccine penetration rates achieved high penetration in the population in most of these countries.
