About the event

During 2020 and 2021, when the observed effects of the COVID-19 pandemic were most severe, there was a substantial increase in all-cause Dutch mortality rates. In this workshop, we explore the results of our research into excess mortality for specific causes during those years. Our model takes socio-economic characteristics and the vaccination status of individuals into account. In addition, we will present results on vaccination uptake in different socio-economic groups.  


In the first part of this workshop, we will discuss how we define and estimate excess mortality during the years 2020 and 2021. This part is based on an extensive study of pre-pandemic mortality from specific causes. The estimated model for pre-pandemic mortality allows us to construct expected mortality rates for specific causes of death based on an individual's characteristics. To further improve our definition of expected mortality we also include a person’s medical expenses from previous years in our model. Based on those expected rates we obtain estimates of excess mortality by cause of death. We will then present results on how the obtained excess mortality rates vary by individuals' characteristics. Part of this analysis will be a comparison between the years 2020 (no vaccination available) and 2021.   


The second part of the workshop will focus on vaccination uptake in different socio-economic groups. We will discuss results on how vaccination uptake varies across ages, income groups and other socio-economic factors. 


The presented results are the outcome of the RCLR research project “The effect of socio-economic characteristics, vaccination information and geographical location on excess mortality from specific causes during the COVID-19 pandemic in the Netherlands”. This project was funded by ZonMw as part of “Lijn 3” of their wider investigation into mortality during the Covid pandemic.

Our research is based on CBS microdata, which contains individual records for people living in the Netherlands. All data were provided by the Centraal Bureau voor de Statistiek (CBS). For more details about microdata see https://www.cbs.nl/en-gb/our-services/customised-services-microdata/microdata-conducting-your-own-research. 

We expect accreditation for 2 Permanent Education Points of the Dutch Actuarial Society (AG).
