CDC reports death data on three sections of the website:
U.S. Cases & Deaths,
COVID Data Tracker, and
NCHS Provisional Death Counts. U.S. Cases and COVID Data Tracker get their information from the same source (total case counts);
however, NCHS Death Counts are based on death certificates that use information reported by physicians, medical examiners, or coroners in the cause-of-death section of each certificate. Data from each of these pages are considered provisional (not complete and pending verification) and are therefore subject to change. Counts from previous weeks are continually revised as more records are received and processed. Because not all jurisdictions report counts daily, counts may increase at different intervals.
