- Our volunteers examine and manually update our numbers once a day, annotating any changes in data sources or anomalies in the numbers states report as they go. Most other trackers rely on automated tools to collect data from public health authorities, so their counts tend to be updated more frequently than ours.
- States count deaths in inconsistent ways, and the various trackers deal with those inconsistent counts differently.
- After the CDC released a testing data tracker, we did a deep analysis of the differences between what the CDC published and what states publish."
