Estimated mortality

In general, some time elapses between the actual date of death and the moment when this data reaches CBS. Death certificates are collected weekly on Thursdays. Usually, mortality data collected on Thursday include slightly over 80 percent of all deaths over the previous week. This information provides an indication of the number of deaths that can be expected for that week.
Based on the data obtained over weeks 12 through 32, death certificates are currently being received sooner than usual (as the number of certificates that was received after one week turned out to cover 85 percent of all deaths) with the exception of weeks with public holidays. The estimate for week 33 is based on the assumption that for this week as well, 85 percent has been received. As the percentage is uncertain, the actual number of deaths in week 33 may be higher or lower as a result.
