The "Weekend" effect
We've known for a long time that there seems to be fewer deaths from Covid over the weekend, and we also know that this isn't because diseases takes a holiday.
But now we have clear data about the cause of the weekend effect. Two thirds of US states, don't make a report over the weekend.
This shows us how important it is to delve into the sources of statistics, and to understand how they are generated. So Florida, a heavy contributor to USA deaths, seems to only report deaths on a Friday. California, on the other hand, reports daily, including Saturday and Sunday.
