New Provisional Mortality Data Now Available Weekly in CDC Wonder

As of September 1st, the National Vital Statistics System (NVSS), part of CDC’s National Center for Health Statistics (NCHS), has changed the frequency of provisional mortality data updates in CDC WONDER from a monthly to a weekly schedule.

This change is part of an ongoing effort to improve the dissemination of vital statistics and allow for more timely insights into death and mortality in the United States. NCHS will continue releasing provisional mortality data in reports and via online dashboards. A schedule of upcoming data releases is available on the NCHS website.

NCHS’ mortality data are the most complete and accurate because they are collected from vital registration systems from across the United States and in U.S. territories.
