David Spiegelhalter is starting a column in The Guardian about COVID-19, the first installment being about excess death statistics. Arguing rightly that it is “fairer to look at what has happened to the total number of deaths”, since this is an objective quantity (in countries with trustworthy death statistics). The discussion on how many of the excess deaths can be attributed to the pandemic is somewhat confusing, though, as little can be said with enough confidence, between the positive impact (flu deaths have plummeted, 30% less traffic deaths in France, &tc.) and the negative impact (stress, harsher economic or social conditions, &tc.) A worthy warning: the deficit in “other” deaths during the second wave is partly due to the extra deaths during the first wave, esp. for fragile and elderly persons.

![INSEE [the French version of the Census Bureau] has started posting weekly mortality rates and comparing them with past years rates. While there is a huge variability at the department level, these rates do not depend on testing or reporting and hence appear as a sounder indicator of the impact of the epidemics, if delayed by a few weeks of infection plus severe deterioration](https://i0.wp.com/xianblog.fr/wp-content/uploads/2020/04/screenshot_2020-04-05-nombre-de-dc3a9cc3a8s-quotidiens-par-dc3a9partement-insee.png?resize=450%2C450&ssl=1)
