What has been the impact of COVID-19 on mortality in the Netherlands? Using the methods described here, I estimated excess mortality in the country during 2020. The results are not pretty: around 15,000 additional deaths, 10% increase over the expected mortality for the year, 25% of the excess not captured by records of official COVID-19-related deaths. The analysis features comparisons of excess mortality over the past 10 years, as well as an exploration of 2020 excess mortality across age and gender. Read it here. You can also check the data and code (in R).
