How are the numbers calculated?

Statistics Netherlands (CBS) weekly publishes the total number of deaths and compares this number with the expected number of deaths. Excess mortality occurs when more people die than expected. So expected mortality is the mortality you would expect if there had been no corona epidemic. This takes into account factors as aging and migration and compares it with the seasonal pattern from the years before. The predicted number of deaths per week have been taken from the mortality projections made once every year by Statistics Netherlands.

The expected number of deaths has a bandwidth with an upper and lower limit (interval). Statistics Netherlands only speaks of excess mortality if the number of deaths is above the interval. Within the interval, it may be an ordinary fluctuation.
