U.S. Provisional Death Counts for Influenza, Pneumonia, and COVID-19 by Week and State

Weekly provisional death counts for influenza, pneumonia, and COVID-19 reported to the National Center for Health Statistics (NCHS). The data is aggregated by week ending date, jurisdiction, and age group, and was last updated on April 21, 2025. It originates from the data.cdc.gov portal via the Socrata platform.

Use Cases

• Analyze temporal trends in COVID-19 Deaths, Influenza Deaths, and Pneumonia Deaths using MMWRweek and MMWRyear.
• Compare mortality burden across Jurisdiction and HHS Region for the combined Pneumonia, Influenza, or COVID-19 Deaths indicator.
• Assess age-specific mortality patterns by cross-tabulating Age Group with cause-specific death columns.
• Calculate provisional mortality rates using Total Deaths as a denominator for specific weeks identified by Start Week and End Week.

Strengths

• Includes multiple cause-of-death indicators (COVID-19, Influenza, Pneumonia) for comparative analysis.
• Provides temporal granularity with weekly data (MMWRweek, Week Ending Date) and geographic granularity by state and HHS region.
• Contains demographic breakdowns via the Age Group column.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Data is provisional and subject to revision, as indicated by the Data As Of and Footnote columns.
