Florida changed its COVID-19 data, creating an ‘artificial decline’ in recent deaths
As cases ballooned in August, however, the Florida Department of Health changed the way it reported death data to the CDC, giving the appearance of a pandemic in decline, an analysis of Florida data by the Miami Herald and el Nuevo Herald found.
On Monday, Florida death data would have shown an average of 262 daily deaths reported to the CDC over the previous week had the health department used its former reporting system, the Herald analysis showed. Instead, the Monday update from Florida showed just 46 “new deaths” per day over the previous seven days.
The dramatic difference is due to a small change in the fine print. Until three weeks ago, data collected by DOH and published on the CDC website counted deaths by the date they were recorded — a common method for producing daily stats used by most states. On Aug. 10, Florida switched its methodology and, along with just a handful of other states, began to tally new deaths by the date the person died.
If you chart deaths by Florida’s new method, based on date of death, it will generally appear — even during a spike like the present — that deaths are on a recent downslope. That’s because it takes time for deaths to be evaluated and death certificates processed. When those deaths finally are tallied, they are assigned to the actual data of death — creating a spike where there once existed a downslope and moving the downslope forward in time.
