Weekly excess mortality by NUTS2-region and age group
The table contains the calendar weeks with excess mortality figures as a frequency and percentage. Excess mortality is detected in a week if the number of reported deaths exceeds the upper limit of the statistical expectation for that week. The extent of excess mortality is then determined by the difference between the number of expected deaths and the number of reported deaths. The excess mortality percentage is the ratio of excess mortality to the expected number of deaths. The extent of the excess mortality percentage is indicated by the colour intensity in the legend.

The number of deaths published for the last five weeks are estimates. They are calculated based on the currently registered deaths and the reporting delays of the individual cantons observed in the past. The annual calculation of the extrapolation weights for the last five weeks of the weekly reporting takes place at the beginning of each year. By taking the reporting delays into account, a realistic forecast of the most recent weekly deaths is achieved. Over time, however, the figures approach the actual numbers of deaths, as the extrapolations made in the preceding weeks are gradually replaced by the actual registered deaths.
